Chess notation
I have a couple of questions about Chess notation on Wikipedia. See Chess notation and Algebraic notation (chess). A good example of current usage on Wikipedia is at Deep Blue versus Garry Kasparov. The official rules are at http://www.fide.com/component/handbook/?view=article&id=125 (FIDE Chess Handbook, E.I.01B (Appendices), Appendix C (Algebraic notation). I believe the United States Chess Federation prefers the FIDE notation but allows descriptive as well.

My questions are:

Hyphen, en dash or em dash? Move 8 of Deep Blue versus Garry Kasparov, 1996, Game 1 (Which I will call DBvK for short) shows a 0-0 (Castle) with an ASCII 2D (hyphen).

Space after period; required, allowed, or forbidden? DBvK has no spaces.

Leading zeros; required, allowed, or forbidden? DBvK has no leading zeros, nor has any chess book I have ever seen. Some chess-playing programs use leading zeros, but that went out of style with MS-DOS.

Capture; small letter x or multiplication sign? Or some other character?

May I assume that Wikipedia's standard is the algebraic notation required by the FIDE with English piece names? Or are figurine piece names also allowed? --Guy Macon (talk) 00:23, 22 May 2012 (UTC)

 * Hyphen or dash - most rulebooks don't say, but Schiller Official Rules of Chess says dash. But I haven't seen an em-dash used for decades.  But Schiller also says to use zeros for castling whereas most of the rulebooks use a letter O.
 * Space after period - as far as I can tell, anything goes.
 * Leading zeros - certainly not required and they are rarely seen.
 * Algebraic notation is the world-wide standard. The USCF allows games to be recorded in descriptive notation, but nothing has been published in that for about 25 years.  I don't think this has been discussed, but the English piece names are used instead of figurines.  Bubba73 You talkin' to me? 01:50, 22 May 2012 (UTC)


 * I think this arises from threads on my talk page and that of Ihardlythinkso, where I've listed some sources:
 * Pitman (in Modern Chess Openings): proper symbol (×) and en dash
 * Bell: proper symbol (but uses a kind of em dash, it seems: certainly not a hyphen)
 * Penguin: proper symbol and en dash
 * Chess Digest: proper symbol and en dash
 * Batsford: proper symbol (but uses hyphen, not en dash)
 * Arco: proper symbol and en dash
 * Imprint Capablanca (heavy-duty chess publishers): proper symbol and en dash
 * Digest: proper symbol and en dash

 * I looked at two more books, Kasparov on Kasparov, Everyman Chess and The Mammoth Book of Chess. In both of them, I could see no difference between the symbol they use for capture and the letter x.  As far as hyphen or dash in castling, definitely not m-dash, but I can't tell the difference between a hyphen and an n-dash in print.  Bubba73 You talkin' to me? 04:06, 22 May 2012 (UTC)
 * Well, they are pretty short so they look like hyphens to me. Bubba73 You talkin' to me? 04:09, 22 May 2012 (UTC)


 * If you want to use the same characters as used in the sources, I would argue that the characters used in the official FIDE laws of chess or USCF rules of chess trump some random chess book. FIDE (ref above) uses these characters:
 * # Octothorpe (ASCII 23)


 * + Plus Sign (ASCII 2B)


 * - Hyphen (ASCII 2D)


 * 0 Zero (ASCII 30)


 * = Equal Sign (ASCII 3D)


 * x Lower Case X (ASCII 78)


 * USCF (example http://main.uschess.org/content/view/11741/141/ ) uses the same characters except for one:
 * O Upper case O (ASCII 4F)


 * One notable primary source looks like this:
 * http://en.wikipedia.org/wiki/File:Fischer_Score_Card.jpg
 * Good luck with that one.
 * While they don't specifically mention chess, If you look at MOS:HYPHEN, MOS:DASH, MOS:EMDASH, and MOS:ENDASH, I think it could be argued that the correct character to use here is the hyphen. Hyphens indicate conjunction, and the use in chess notation (particularly long algebraic) is a lot more like a conjunction than it is like anything in the dash descriptions. --Guy Macon (talk) 08:09, 22 May 2012 (UTC)
 * I agree and think we should follow the FIDE algebraic notation, which USCF says they use too. Btw, here is another link for USCF Other symbols: Castling- 0-0 ; Queenside castling- 0-0-0 ; Capture- x (i.e. BxNf6 means bishop captures knight on f6) ; Check- + ; Checkmate- ++ OR # ; White wins- 1-0 ; Black wins- 0-1 ; d pawn promotes to a queen- d8=Q ; Good move- ! ; Bad move- ? ;  Brilliant, soul searing move- !!  ; Blunder- ?? ; Interesting move !? ; Dubious move ?! . I have checked their official rule book (preview in amazon) and it is the same there, except the use of the letter O in castling. Voorlandt (talk) 09:13, 22 May 2012 (UTC)
 * That looks like the best solution. I think we can ignore the USCF O and use 0 - every other country except the US uses FIDE rules, including New Zealand, Australia, Canada and the UK. One other detail; FIDE uses capital letters for pieces (B for Bishop) and lower case letters for squares (square b4). --Guy Macon (talk) 09:51, 22 May 2012 (UTC)

The FIDE source is a web page, and web pages tend to stick to ASCII. That doesn't mean that a print source would stick to ASCII. Also, for castling they use a spaced hyphen, which is a conventional ASCII substitution for an en dash. Given all the print sources which use ⟨×⟩ and ⟨–⟩, that's probably what we should do here. — kwami (talk) 10:42, 22 May 2012 (UTC)
 * It is a good point that web pages tend to stick to ASCII, so here are links to the print versions of the rules of both FIDE Appendix C and USCF: USCF, page 214-..; regards, Voorlandt (talk) 10:49, 22 May 2012 (UTC)
 * Any Wikipedia copyeditor familiar with WP:ENDASH would expect 1–0 (White wins), along with 0–1 and ½–½, using a dash because they resemble a sports score. Art LaPella (talk) 14:26, 22 May 2012 (UTC)
 * I agree, but reporting the result of a game or tournament is not actually part of chess notation, which serves to document the moves made in the game. FIDE-standard algebraic notation only uses a hyphen for castling (0-0 and 0-0-0), but long algebraic notation uses a hyphen for most moves (Nb1-c3) as does reversible algebraic notation.
 * Alas, baseball doesn't seem to use "1-2, 2-3" to indicate two runners on 1st and 2nd base advancing to 2nd and 3rd base, but if it did, I suspect that it would use a hyphen. The closest analogy on Wikipedia I could find was at Odds, where I find "a more common use is "odds against", of the form 6 to 1, 6-1, 6:1, or 6/1 (all read as 'six-to-one')" . --Guy Macon (talk) 17:28, 22 May 2012 (UTC)


 * As far as hyphen versus dash (either one) and the "x" used in capture, I suggest that the ones that are available on a standard keyboard be used, i.e. a hyphen and a lower-case letter x. Bubba73 You talkin' to me? 22:53, 22 May 2012 (UTC)


 * I would also note that while the FIDE Laws of Chess(Appendix C, pages 18-20) appears to specify 0 - 0 - 0, the sample game at the top of page 20 makes it clear that 0-0-0 is to be used. --Guy Macon (talk) 02:17, 23 May 2012 (UTC)
 * To me, specifying 0 - 0 - 0 and then using 0-0-0 in the sample, makes it clear that whoever wrote that doesn't consider spacing to be an important difference, and it seems unlikely he cares about hyphens vs. dashes either. Art LaPella (talk) 02:42, 23 May 2012 (UTC)
 * Wholly agree w/ Art. There are so many absent notation standards needing attention, why waste this good opportunity seeing "ghosts" in minutae (Tony1's "scrutinizing sources" for diffs between "×" vs "x", castling hyphens vs endashes)? Are we gonna blow this opportunity now that the topic of notation convention finally has attention? Or set some standards for uniformity, of which there are precious few? Ihardlythinkso (talk) 03:32, 23 May 2012 (UTC)

Take-aways
OMG! The discussion is seeming to center on what s/b uniform notation conventions, across all articles. (I hadn't presumed that from Tony; it wasn't clear to me he wasn't meaning article-specific styling to mirror what's in respective sources.) But the topic of an agreed consistent notation for WP chess articles is a great topic IMO (since I for one think uniformity across articles is a good thing for readability).

How about some "take-aways" from this discussion!? Updating either MOS for chess, or ProjChess conventions!? (There is a ProjChess convention "White/Black" refer to players; "white/black" refer to pieces, but little other strong conventions, beyond the obvious, like B = bishop, etc. And I'd assumed "x" for captures, and hyphens for castles, were in the obvious camp, until now, since they've never been questioned until now. I assume they won't change.) Ihardlythinkso (talk) 23:43, 22 May 2012 (UTC)

Will we have any "take-aways" on any of these (consensus for ProjChess conventions, or MOS guides), or do we just let all this get archived and forgotten about? Tony1 made changes to Morphy versus the Duke of Brunswick and Count Isouard regarding item 'n' (changing captures, e.g. "dxe5" to "d×e5") and 'm' (changing castles, e.g. "0-0-0" to "0–0–0"), I questioned him on it at his User Talk, he was insistent, even though his notation styling is inconsistent w/ 99.99% chess articles. I opened the issue on the article Talk, but someone opened a thread here, and Tony1 asked if discussion could be moved from article Talk to here (although I don't see any participation by Tony1 here). That is why there is this discussion here (it wasn't my idea to open a thread at MOS, only at article Talk). So, what happens back at Morphy versus the Duke of Brunswick and Count Isouard as a result of this thread, which replaced the discussion at article Talk? Will we determine consensus on at least items 'n' and 'm' below so Morphy versus the Duke of Brunswick and Count Isouard can be resolved? Or will it be allowed, through lack of whatever, that yet another notation styling—am pretty sure not seen before in any WP chess article—to add to the convention inconsistencies WP already has, documented below? Ihardlythinkso (talk) 12:34, 28 May 2012 (UTC)

Without conclusion(s) drawn regarding consensus on the item(s), other than on some which seem to be governed already by MOS (like "1–0" versus "1-0"), there'll be no ProjChess convention or MOS guide to prefer any of the options listed over other option(s). In that case, one would like to think precedence should be honored (e.g., "exd5" occurring in 99.99% articles, not "e×d5"), rather than the chaos (inconsistencies) whereby any editor reverts any other based on personal preference (for whatever reason). But in some cases there isn't a clear precedent (e.g., there are plenty of "O-O-O"s in articles as well as "0-0-0"s), so there's nothing to stop the chaos (inconsistencies) brought on by repeated reversions. (Which *does* happen. Ditto for "1... e5" versus "1. ... e5", etc.). This MOS thread was supposedly opened to resolve one or more of these differences of preference. Has it? Will there be any take-away result(s) (consensus)? (If not, is there a WP Guide giving preference to existing precedent in articles, when there clearly is one? Or is it assumed editors should respect any overwhelming precedent already in-place?) Ihardlythinkso (talk) 11:27, 1 June 2012 (UTC)

a. 0-0-0 vs. O-O-O
(It'd be nice to get some policy on it, so editors stop reverting one another based on personal taste! My own "kinky" preference is that 0-0-0 is always used, but O-O-O for pre-1900 games, to make them look "antiquish". But I realize that sounds silly, and my own preference isn't important anyway. Ihardlythinkso (talk) 23:43, 22 May 2012 (UTC))


 * Portable Game Notation uses letter O, in contrast to most publications. Personally, I just write circles, but I prefer letter O to zero.  Bubba73 You talkin' to me? 03:23, 23 May 2012 (UTC)


 * The Laws of Chess and their Interpretation by Golombek uses O. Bubba73 You talkin' to me? 03:39, 23 May 2012 (UTC)


 * I personally draw Os when recording a game, but when playing over games (reading), I prefer to see 0s. (It looks more "modern". Plus WP's own reference for this, article Algebraic notation, uses 0s not Os – see section Castling. Ihardlythinkso (talk) 13:19, 28 May 2012 (UTC)) But if the WP future is figurine notation and PGN (as [here]), then are we best off positioning for that now, with "O–O–O"?! Ihardlythinkso (talk) 04:13, 23 May 2012 (UTC)


 * 0-0-0 per FIDE Laws of Chess Appendix C. (OTOH, note that USCF rules and Portable Game Notation use O-O-O) --Guy Macon (talk) 05:28, 23 May 2012 (UTC)
 * The appendix is ambiguous. They imply <0–0–0>. — kwami (talk) 18:07, 23 May 2012 (UTC)
 * That's not true. Look at the top of page 20. The PDF uses the binary code for ASCII 0, not ASCII O, and ASCII -, not Unicode –. --Guy Macon (talk) 20:11, 23 May 2012 (UTC)

Is it fair to say there is no CONSENSUS, therefore editors should feel free in WP chess articles to continue reverting one another till the cows come home based on personal taste? Ihardlythinkso (talk) 20:11, 28 May 2012 (UTC)


 * The above conversation is funny. Any chess organisation gives notation rules for players to follow. Plays 'write moves down on paper as the moves are played. They are written, with a real pen/pencil etc, no one care if the players castle is written with a zero or a letter 'O' because as written on a piece of paper it does not matter. So don't read to much into it, that is why FIDE say use 0-0-0 but give example with O-O-O interchangably. Regards, SunCreator (talk) 22:55, 10 June 2012 (UTC)
 * We could write out our article by hand and scan them up. We have higher and different standards here. Tony   (talk)  23:13, 10 June 2012 (UTC)
 * @Ihardlythinkso: “there is no CONSENSUS” wouldn't mean “editors should feel free in WP chess articles to continue reverting one another till the cows come home based on personal taste”, it would mean “leave stuff the hell alone”. ― A. di M.​  08:43, 11 June 2012 (UTC)
 * A. di M., please clarify. I was describing what actually happens (reverts, according to taste). What are you describing? Your link goes only to MOS in general. Have no idea what your idea is. Ihardlythinkso (talk) 11:00, 12 June 2012 (UTC)

b. (1.e4) vs. (1. e4) vs. (1 e4)
(It'd be nice to get some policy on it, because as can be seen here, some editors have personal taste that is different: Semi-Slav Defense. Ihardlythinkso (talk) 23:43, 22 May 2012 (UTC))

(I really think this difference [1.e4 vs. 1. e4] s/ *not* be standardized, I think that's going too far. [I've changed my view of this, at first I thought a standard would be good. But I now think that's too inflexible. Sometimes w/o space works best, sometimes with, for different situations. There are many situations, making a hard rule too blunt: horizontal gamescores, vertical gamescores, horizontal gamescores sliced w/ commentary, ditto vertical, use in section titles, infoboxes, etc. All of them have different effects, making the issue too complex for one-size-fits-all. {The original idea to have *both* for diff situations was not mine, but another editor in discussion on notation styles at ProjChess. The idea seemed odd to me when I read it, but after more editing experience I see he was right!}] But I do think that in horizontal gamescores where moves are all in bold, "1. e4" s/b preferred, to give all that crowded blackness some breathing room, for easier-on-the-eyes reading. But an influential member at ProjChess disagrees with that. Anyway! I say not to touch this, the downside being, there may be back-and-forth reverts between users on personal preferences – in fact the reason I opened a discussion on ProjChess was due to a back-and-forth reversion! I think this issue is really complex, and is really confusing therefore. Ihardlythinkso (talk) 23:43, 22 May 2012 (UTC))
 * I don't like the period to be omitted, and I think it is rare. I prefer a space after the period.  Bubba73 You talkin' to me? 03:26, 23 May 2012 (UTC)
 * I think I agree. (Especially for bold.) Chess Life uses the space consistently. But User:MrsHudson prefers without the space (Wikipedia talk:WikiProject Chess/FAQ/Format.) I wonder how dropping the space came about, and why. I can see advantage in big blocks of horizontal gamescore for compactness/space savings, and you can get "more in" a given line in an Infobox, circumventing spillover to a new line. But in columnar presentations (e.g. intro moves in most openings articles), the space is always used. But in TOCs, the space in section titles makes things look more confusing ("2.1 1. e4" vs. "2.1 1.e4"). So I think blanket application is probably a mistake; too many situations. (Not sure what's best!) Ihardlythinkso (talk) 04:35, 23 May 2012 (UTC) p.s. I agree "1 e4" is bad of course. (But at least a couple ProjChess members, including User:Quale, thought it looks best: Wikipedia talk:WikiProject Chess/FAQ/Format.)


 * I agree that the space does make a TOC entry confusing, so don't use a space in a section title. Bubba73 You talkin' to me? 04:45, 23 May 2012 (UTC)


 * The FIDE Laws of Chess Appendix C. (top of page 20) specifies 1. e4 (FIDE website mostly conforms to this, but occasionally does not) --Guy Macon (talk) 05:28, 23 May 2012 (UTC)


 * I'd use 1. e4, with a non-breaking space. Maybe a thin space would look better (1. e4), but the KISS principle applies. ― A. di M.​   13:41, 23 May 2012 (UTC)
 * di M., is the "thin space" supposed to be less wide than a non-breaking space? (Because on my computer, it is creating *more* separation than the non-breaking space, not less.) Ihardlythinkso (talk) 21:26, 23 May 2012 (UTC)

Re "1 e4": Is it fair to say there is CONSENSUS to never use that notation style (without dot) in WP chess articles? Re "1.e4" vs "1. e4": (I'm staying out of this topic, as noted above.) Ihardlythinkso (talk) 21:04, 28 May 2012 (UTC)


 * c. (1...Nf6 or 1 ...Nf6) vs. (1. ...Nf6 or 1. ... Nf6)

c. (1...Nf6 or 1... Nf6) vs. (1. ...Nf6 or 1. ... Nf6)
(There's plenty of discord regarding which s/b used, and I've seen reversions back-and-forth based on personal preference also. I'm sure the first will be chosen, but would be nice to have some policy on it, to resolve the matter. [Chess Life uses the latter, a decision I don't understand, but hey!] Ihardlythinkso (talk) 23:43, 22 May 2012 (UTC))


 * Also 1... Nf6 is used (like the second one, but the space is after the three periods). I've flip-flopped on this, but for the last couple of years I've preferred 1... Nf6.  Bubba73 You talkin' to me? 03:28, 23 May 2012 (UTC)
 * That's my fault (I meant 1... Nf6 but incorrectly typed 1 ...Nf6 in the subsection title). Sorry for confusion. Ihardlythinkso (talk) 04:10, 23 May 2012 (UTC)


 * 1...Nf6 when a number is specified, ...Nf6 if no number per FIDE usage --Guy Macon (talk) 05:28, 23 May 2012 (UTC)

Is it fair to say there is CONSENSUS to always use 1...Nf6 or 1... Nf6 for notating Black moves in WP chess articles, and not 1. ...Nf6 or 1. ... Nf6?

d. (1–0, 0–1, ½–½) vs. (1-0, 0-1, ½-½)
(Again I assume the first will be chosen; I agree w/ Art. But it would be nice to have a standard in policy, so there's no question. Ihardlythinkso (talk) 23:43, 22 May 2012 (UTC))
 * I prefer the one that we have on a standard keyboard. But I do strongly prefer ½-½ to 0.5-0.5, or he scored 6½ points over 6.5 points.  Bubba73 You talkin' to me? 03:30, 23 May 2012 (UTC)


 * I prefer fractions too, but just discovered this: "The use of the few Unicode symbols available for fractions (such as ½) is discouraged entirely, for accessibility reasons among others." (Manual of Style/Dates and numbers. Have I misinterpreted it!?) Ihardlythinkso (talk) 07:39, 29 May 2012 (UTC)


 * Excellent find! Now we have a third answer. Manual of Style/Dates and numbers does not say we should use
 * &#189; ( Unicode VULGAR FRACTION ONE HALF [ UTF-8 Hex C2 BD = &amp;frac12; = &amp;#189; ] )
 * or
 * 1/2 ( ASCII 1, /, 2 ).
 * It says we should use
 * $1/2$ ( WikiMarkup $1/2$ ),
 * which gives us
 * 1&#8260;2 ( Superscript ASCII 1, Unicode FRACTION SLASH [ UTF-8 Hex E2 81 84 = &amp;frasl; = &amp;#8260; ] ), Subscript ASCII 2 ).
 * --Guy Macon (talk) 12:53, 29 May 2012 (UTC)


 * Not a part of chess notation, so MOS rules for reporting scores of sporting events apply. FIDE use is inconsistent, sometimes 1-0, 0-1 and 1/2-1/2, sometimes 1-0, 0-1, ½-½. --Guy Macon (talk) 05:28, 23 May 2012 (UTC)

Is it fair to say there is CONSENSUS to use endashes (as according to MOS) when reporting these scores in WP chess articles, and not hyphens?


 * What part of MOS? --Guy Macon (talk) 12:53, 29 May 2012 (UTC)


 * MOS:ENDASH. "2. In compounds when the connection might otherwise be expressed with to, versus, and, or between. Here the relationship is thought of as parallel, symmetric, equal, oppositional, or at least involving separate or independent elements. The components may be nouns, adjectives, verbs, or any other independent part of speech."
 * In the list of examples given, this one: "a 51–30 win; a six–two majority decision" Ihardlythinkso (talk) 18:43, 29 May 2012 (UTC)

e. (+5 −1 =3) vs. (+5−1=3) vs. (+5 =3 −1) vs. (+5=3−1)
(For match and tournament scores. Again I assume the first will be chosen. That's why I've spent time on several articles on major players [ Fischer, Alekhine, Karpov, Kasparov, Lasker, Steinitz, etc.] making them uniformly +W −L =D, following the lead of some of the more consistent major articles. But it was a lot of work! [And not complete for those articles.] And there are different ways to report scores in RSs [e.g. The Oxford Companion uses +W=D−L]. Of course I personally prefer the former [wins & losses are more "dramatic" and s/b listed first IMO], but again my preference is not important; consistency is the desirable goal, and a policy now could help that end. Ihardlythinkso (talk) 23:43, 22 May 2012 (UTC))


 * I brought this up at the Chess project talk page. Some non-chessplayers don't understand what the = means. I prefer something like (W5,L1,D3) - much clearer.  Bubba73 You talkin' to me? 03:32, 23 May 2012 (UTC)


 * Not a part of chess notation. Is there something in MOS that specifies win/draw/loss for sporting events? FIDE uses +W=D-l. All variations seem confusing to newcomers. --Guy Macon (talk) 05:28, 23 May 2012 (UTC)


 * Probably should hold of on "spending time on several articles making them uniform" until a consensus is reached as to what we should standardize on. --Guy Macon (talk) 15:20, 23 May 2012 (UTC)
 * I've understood my time might so be wasted, but my expectation that an agreed-upon standard will be reached is that this will occur sometime in the year 2025 (or like the song, "in the year 2525, if Man is still alive"). Ihardlythinkso (talk) 21:25, 28 May 2012 (UTC)

f. (+/−, −/+, −+, +−) vs. (+/-, -/+, +-, -+) vs. (+/–, –/+, +–, –+)
(I assume the first will be chosen [the arithmetic minus sign]. But there is no policy now for evaluation expessions, as well as for Black [−/+ vs. -/+]. Ihardlythinkso (talk) 23:43, 22 May 2012 (UTC))
 * I prefer the one that a standard keyboard has. Bubba73 You talkin' to me? 03:33, 23 May 2012 (UTC)


 * The problem with sticking to ASCII is that it looks amateurish. You can always write it in ASCII, of course, and s.o. will clean up after you. Also, when we mean 'minus', we already have the standard of writing it as minus rather than as a hyphen. — kwami (talk) 04:26, 23 May 2012 (UTC)
 * Really? I think ASCII looks modern - as if a computer was used instead of 19th-century printing technology.  Bubba73 You talkin' to me? 05:01, 23 May 2012 (UTC)
 * Well, I think Unicode looks even more modern –as if modern fonts were used instead of 20th-century character encodings. ;-) (And the hyphen looks mismatched to me.) ― A. di M.​  13:45, 23 May 2012 (UTC)
 * The minus is at the same level as, and the same length as, the horiztal bar in "+", so to me minus looks hands-down "cleaner" (neater, more organized). (WP provides the special char clickable, of course, below the edit summary box.) Ihardlythinkso (talk) 04:44, 23 May 2012 (UTC)


 * This is widely used in engineering and statistics. Is there already a MOS entry for it? --Guy Macon (talk) 05:28, 23 May 2012 (UTC)


 * Previous discussions: Manual of Style and WikiProject Chess.


 * Text readers will say the correct words if the real minus sign is used instead of the hyphen. Everything in the manual of style points to using the correct symbol, not a shortcut. Binksternet (talk) 16:08, 23 May 2012 (UTC)


 * As far as I am concerned, what Binksternet wrote above settles the issue. We do not make decisions that make things harder on the visually impaired because we like the way they look. Not only is designing for screen readers the right thing to do, we are required by the Americans with Disabilities Act to make reasonable accommodations for users with screen readers. --Guy Macon (talk) 16:30, 23 May 2012 (UTC)


 * Article Punctuation (chess) gives =/∞, +/=, +/−, and +−. I guess in this "take-away" I'm asking if we can make that policy, so when hyphens are found in articles they can be replaced (with minuses). In this ProjChess discussion, User:ZeroOne points out &#177; and &#8723; are available, but no equivalents with "=" (except that User:Casaschi explains how to make them, giving an example/link). In the same discussion, Quale preferred English prose over evaluation symbols in WP articles, reserving symbol use for chess. Ihardlythinkso (talk) 22:29, 23 May 2012 (UTC)
 * Good find! I strongly agree with you about standardizing. For example, we can standardize on hyphens. We can standardize on en dashes.

 * I checked some British case law (here). Trawling through the text, I saw that the preferred abbreviation was "v" - no period, no "s". Of course, that might just be what this particlar judge prefers. Martinvl (talk) 13:37, 23 May 2012 (UTC)

h. d8Q vs. d8=Q vs. d8(Q) vs. d8/Q
(For WP, do we prefer one of these? If not, we'll get all of them! Ihardlythinkso (talk) 23:43, 22 May 2012 (UTC))


 * The first one is mainly used only where you are trying to save paper (Informat is an example), so I think it is the least preferred on WP. Then =Q is my first choice and (Q) is my second choice.  (Note that you can't put an = in a caption unless you enclose it in two sets of braces.)  Bubba73 You talkin' to me? 03:42, 23 May 2012 (UTC)


 * I guess I'd agree, that d8=Q is best (with other conventions already assumed standard, like inclusion of "+" for check, and "x" for captures). (And I just noticed that Chess Life also uses "=Q".) Ihardlythinkso (talk) 04:47, 23 May 2012 (UTC)


 * d8Q per FIDE Laws of Chess Appendix C. --Guy Macon (talk) 05:28, 23 May 2012 (UTC)


 * OK. Bubba73 You talkin' to me? 23:33, 23 May 2012 (UTC)


 * But we aren't obligated to follow suit w/ the FIDE handbook. For example Chess Life uses d8=Q, and I think that convention would be less confusing for new readers than d8Q. Ihardlythinkso (talk) 13:25, 28 May 2012 (UTC)
 * Here's another argument to consider: Minimal algegraic notation (MAN) uses ed5 or ed instead of exd5, and Qh7 instead of Qh7+. MAN also uses d8Q. Wouldn't it be advisable and/or consistent then, to continue the pattern of differentiation from MAN in WP chess articles, by using d8=Q (or d8(Q) or d8/Q) instead of d8Q? Ihardlythinkso (talk) 20:50, 28 May 2012 (UTC)


 * d8Q is, to me, just ugly. It appears more common to omit the sign when using figurine notation, e.g. The Mammoth Book of Chess uses d8♕. d8/Q is old and isn't used much. d8=Q is the clearest and probably the most used. d8(Q) is OK, but I find the one with the equals sign clearer.

Out of curiosity I checked Chess Life, and they use: gxh6 e.p. (italicized!). (Feb 2012 Chess Life, p. 49.) WHICH WOULD REALLY MAKE SENSE for WP too, since term en passant is always italic.

(It's never been explicitly stated before, but in WP articles, I've assumed longhand algebraic is never implied by these kinds of expressions, rather, endash means "from square x to square y". [If it were really longhand algebraic, then I assume ...e7-e5 would be correct [not ...e7–e5]. But I've never seen a case in any article, where the meaning needed or intended to be longhand.

 * Bubba, you can write it however you like. The MOS is for the style we expect for an FA.

 * The Mammoth Book of Chess (App. B) says, "In long algebraic notation ... a dash [is] placed between the departure and arrival squares". — kwami (talk) 18:20, 23 May 2012 (UTC)
 * But I don't think the sample descriptions intend to be actual longform notation. Rather, they are just a shorthand in lieu of more lengthy English text descriptions. (This type of technique is used in lotsa openings articles, lots! For example, here it's used four times in the first couple paragraphs: Sicilian Defence, Dragon Variation.) I don't think WP needs to have even one occurrence of actual longform notation – just like there's never a need for occurence of another notation system, like descriptive, in any article. (Except of course in context where such system is described/explained.) I think MOS applies when using the shorthand, as it does in "the a1–h8 diagonal", "[ECO] C55–C56", "page 38–39", etc. (The reason am making the distinction at all, is that it's not certain to me that longform algegraic shouldn't use hyphen!) Ihardlythinkso (talk) 20:07, 23 May 2012 (UTC)


 * Right - there is a difference between a sequence of moves like this and the long form notation. Bubba73 You talkin' to me? 23:36, 23 May 2012 (UTC)


 * Not really on the topic of MOS Chess Notation, but is it even legal under either USCF or FIDE rules to record your game in long algebraic or reversible algebraic?

Is it fair to say there is CONSENSUS that when these type descriptions are used in chess articles, and according to existing MOS, dashes are to be used, not hyphens? Ihardlythinkso (talk) 20:21, 28 May 2012 (UTC)

k. + vs. ++
(I don't think I've actually seen ++ for "double-check" in any article, so this is really picky, but for completeness while we're on the topic, how about making + standard when there's a double-check, instead of ++? ["++" is probaby just very old-fasioned. Let's help it die!] Ihardlythinkso (talk) 23:43, 22 May 2012 (UTC))


 * To me, ++ means checkmate, so double check would be confusing at best. Art LaPella (talk) 00:49, 23 May 2012 (UTC)
 * I agree. But see Double check. (It might cause reverts, w/o a policy.) Ok, Ihardlythinkso (talk) 01:25, 23 May 2012 (UTC)


 * I think ++ is used for double check in some other articles. I use # for checkmate, and I normally don't indicate double check, so I prefer just a single + for double check. Bubba73 You talkin' to me? 03:48, 23 May 2012 (UTC)


 * I use "X" for checkmate ( ala ECO oops! – I don't remember where I picked up use of "X"; ECO uses "#"), but for WP, "#". I agree, ignore notating double-check. Ihardlythinkso (talk) 04:51, 23 May 2012 (UTC)


 * There is no "+ vs. ++". "+" means check and "++" (or "#") means checkmate per FIDE Laws of Chess Appendix C --Guy Macon (talk) 05:28, 23 May 2012 (UTC)


 * I'd be unambiguous and use # for checkmate, and just + for double check (except in unusual circumstances such as the double check article itself). ― A. di M.​  13:47, 23 May 2012 (UTC)


 * I agree with that - generally don't indicate double check, except where it specifically needs to be noted, as in the double check article and conceivably a few others. Bubba73 You talkin' to me? 23:39, 23 May 2012 (UTC)

Is it fair to say there is CONSENSUS that only + be used for double-check in chess articles, save one (the Double check article)? Ihardlythinkso (talk) 20:16, 28 May 2012 (UTC)


 * Although I like the ++ (it's very intuitive), when a game has a double check, the double check is usually notable enough to mention in the annotation, and the double check article will probably be linked, so I don't mind standardising on the single +. The potential confusion between the two uses of ++ (double check and checkmate) is something I would prefer to avoid. Double sharp (talk) 15:15, 13 June 2012 (UTC)

l. (28. Qxh7# 1–0) vs. (28. Qxh7#)
(Really picky again, but it crops up on occasion. Is "# 1–0" redundant? Or should an endashed result follow *all* completed gamescores? Ihardlythinkso (talk) 00:24, 23 May 2012 (UTC))


 * It is redundant, but I don't mind it being there. Bubba73 You talkin' to me? 03:50, 23 May 2012 (UTC)


 * I think looks more professional & "complete" having 1–0 there. (For sure gamescores are consistent too, whether mate or not.) I just noticed Chess Life uses "[move], Black resigned.", "[move], White resigned.", "[move] mate.", "[move], Draw.", and "[move], Draw agreed." (But hey!) Ihardlythinkso (talk) 04:54, 23 May 2012 (UTC)


 * This needs more discussion. The two have different meanings. # means checkmate, wheras 1-0 means a win, which could be through resignation, a 1-point bye, time loss, etc. In theory, # 0-1 is possible (White checkmates and loses). This could happen if an abitrator observes White's flag falling, followed by White checkmating Black before the arbitrator could announce the time loss for White. It could also happen if cheating was discovered. The FIDE rules do not specify how to record an accepted draw, but 1/2-1/2 or ½-½ is usually used. --Guy Macon (talk) 05:28, 23 May 2012 (UTC)


 * The two options listed are meant to be mutually exclusive (picking one or the other, when "#" occurs in a WP gamescore). Since "#" is in both, resignation, 1-point bye, and time loss, don't apply. Regarding White checkmating and losing, assuming that's really a gamescore possibility, it would be so rare, that without clarifying text, "28. Qxh7# 0–1" would be interpreted by the reader, or an editor, as a typo. (So, there'd always *have* to be clarifying text. So again, that add'l text wouldn't relate to which of the two above choices should be selected.) Ditto "cheating" (assuming that is a possibility in a gamescore, too, another rarified event demanding accompanying explanatory text). How to express draws is a valid item, but would be its own different item, not this one. So I don't see anything needing discussion here, regarding the orig two choices listed in this item.

 * What do you mean "FIDE doesn't distinguish <×> from "? In every FIDE document that I have checked, FIDE only uses x (lower case letter x). --Guy Macon (talk) 20:02, 23 May 2012 (UTC)
 * They have, which means they aren't distinguishing <×> from . Their use of  is therefore not evidence that it should be  rather than <×> (which maybe it should be). — kwami (talk) 22:48, 23 May 2012 (UTC)


 * In the MENSA Guide, they do have the multiplication symbol in <8×8>, but still use the letter ex for capture. Though they don't bother much with typography, so that isn't as convincing as it might be. — kwami (talk) 18:12, 23 May 2012 (UTC)
 * The Mammoth Book of Chess says, "A capture is indicated by a multiplication sign (or simply a letter x) before the arrival square." (App. B, p 553) — kwami (talk) 18:20, 23 May 2012 (UTC)


 * Totally agree with A. di M. Plus, if the eight books listed by Tony1 were intended to be basis indicating what's used by chess sources generally, um, the number of chess publs past & present make a sampling of eight stack up to less than 0.01 of one percent. (I'm sure I could list five times that number of books as counterexamples given a half-hour, just out of my own personal library.) Ihardlythinkso (talk) 21:49, 23 May 2012 (UTC)
 * WP's own reference for this, article Algebraic notation, doesn't even mention the multiplication symbol – see section Notation for captures. Ihardlythinkso (talk) 13:03, 28 May 2012 (UTC)
 * If 99.99% of WP chess articles use dxe5 (is anyone finding a single article using d×e5 beyond the article Tony1 changed?), then doesn't the burden to change notation in articles (from x to ×) fall on the proposer(s) for the change? Tony1 presumably attempted to meet the burden by listing eight chess books as sources, and User:Kwami has pointed out The Mammouth Book of Chess says × or x are acceptable. Do these arguments sufficiently meet the buden to warrant introduction of a new notation for captures (×) inconsistent with all existing WP chess articles? Ihardlythinkso (talk) 19:57, 28 May 2012 (UTC)
 * Actually, we are allowed to make decisions at MOS that require changing large numbers of articles, and we are not bound by what has been done before - although those are certainly considerations. I agree with your conclusion, but not with your reasons. We should standardize on the lower-case X instead of the multiplication sign because FIDE does. --Guy Macon (talk) 20:25, 28 May 2012 (UTC)
 * Not that we are *bound* by what is in 99.99% chess articles already – just that the burden of demonstrating that massive precedent should be changed, should fall on the proposers of the change. (Rather than reverse logic, of placing a burden on others to defend why a massive precedent already in place, should be kept.) Ihardlythinkso (talk) 19:02, 29 May 2012 (UTC)
 * Even though The Mammoth Book of Chess says both are acceptable, it uses the lower-case X throughout. I find "x" the best, not just because most sources use it, but also because it just seems more logical to the beginner. If the beginner sees "Bxg7", it would be clearer that it's a capture because the "x" implies that something was "xed" on g7 – i.e. a capture took place there. "B×g7" would be more confusing, since the times sign has a completely different connotation. Double sharp (talk) 15:10, 13 June 2012 (UTC)

n. (12. 0-0-0) vs. (12. 0–0–0)
(For completeness, what Tony brought up originally. I think most have already weighed in; I assume we won't be changing the standard "0-0-0" [hyphens] currently in use in articles. Ihardlythinkso (talk) 08:33, 24 May 2012 (UTC))


 * I'd prefer dashes with Os (O–O–O), but I'd be OK with hyphens and zeros (0-0-0), whereas 0–0–0 and O-O-O would look mismatched to me. ― A. di M.​  13:38, 23 May 2012 (UTC)


 * 0-0-0 per FIDE Laws of Chess Appendix C. --Guy Macon (talk) 16:34, 23 May 2012 (UTC)

 * Look at the top of page 20 and tell me what you see. Also, the characters you keep using to enclose examples is driving the Wikipedia editing screen nuts. I have to keep replacing them with just to reply to you. --Guy Macon (talk) 22:00, 23 May 2012 (UTC)
 * They have <0-0-0> in the example, but <0 - 0 - 0> at the bottom of p19 where they define the symbols. — kwami (talk) 22:46, 23 May 2012 (UTC)


 * I don't know what would be mismatched about dashes and zeros: that's how a score would read. — kwami (talk) 17:58, 23 May 2012 (UTC)


 * Barnes has  etc. for descriptive, and <0–0–0> for castling. — kwami (talk) 18:28, 23 May 2012 (UTC)


 * WP's own reference for this, article Algebraic notation, uses hyphens not dashes – see section Castling. No WP chess articles I'm aware of, save Morphy versus the Duke modified by Tony1, uses dashes. (That kind of consistency has got to mean something, and count for something! If 99.99% of WP chess articles use 0-0-0 [does anyone find a single article using 0–0–0 beyond the article Tony1 changed?], then doesn't the burden to change notation in articles from hyphens to dashes fall on the proposer for the change? Has the burden been met, warranting introduction of a new notation for castles inconsistent with all existing WP chess articles?) I think dashes look odd and are a distraction when playing over gamescores, waste horizontal space for no reason, and are inconsistent with 99.99 percent current chess articles. Ihardlythinkso (talk) 13:13, 28 May 2012 (UTC)


 * Wouldn't 0–0 (kingside castle with zeroes and an en dash) collide with what happens with a double forfeit (neither player comes to the board, and the game is lost by both)? Whatever is adopted, I'd prefer that the kingside and queenside castles (and the Pam–Krabbé joke vertical castling 0-0-0-0) be consistent. Double sharp (talk) 15:10, 13 June 2012 (UTC)

[These examples could be rewritten to circumvent of course, but often times players do talk and write like this.] Ihardlythinkso (talk) 08:33, 24 May 2012 (UTC))

 * Ok ... For "white side", I assume these would all fall in the same bushel basket: (white) "position", "center", "king's wing/queen's wing", "setup/configuration/structure", "castle position", etc.? And for "White move", these are in the same basket: (White) "combination", "attack/defense", "fork/pin/trap/shot/sacrifice", "strategy/plan/idea", "advantage/edge/initiative", etc.?

Using the sources
I haven't found a convincing reason that the multiplication sign and en dash shouldn't be used in WP's chess articles. The most authoritative sources almost all use both. As someone points out above, the MoS does discuss changes that involve a large number of articles, and it's particularly relevant when the notation has not been properly discussed before.

A script could easily be written to manage the changes. Tony  (talk)  00:01, 29 May 2012 (UTC)


 * "Easily" is exaggerated. It would need to change "12. Bxc3 N(5)xc3", "15 ...fxg", "R(a)xe2", "Nxh6+", "55. Kxg5!" "Qxh7#", "Why not 23. fxg5?", "43. bxc e. p. fxe1=Q", and "Kasparov should have played exf, immediately", but not change "Qf7 X" (one editor said he used X for checkmate), "6. examine each entry", "setup.exe", "license plate BXC3", "stock symbol GXH", "|title=How New AXB Regulations Affect You|", or "call sign EXF32 on a DX-pedition". And anything else I wouldn't anticipate until I tried it. I think I'd rather fix problems like speling first. Art LaPella (talk) 02:07, 30 May 2012 (UTC)


 * "The most authoritative sources almost all use both." Wow. Please quantify that. (What do you consider "the most authoritative sources"?) If you found eight books using "×", would you like to see a list of 80, that don't? And a logic question: How does "sources almost all use both" justify using a script to change a massive number of chess articles over to a lesser-used symbol? Ihardlythinkso (talk) 03:31, 30 May 2012 (UTC)


 * Tony1, may I ask ... To what extent is chess in your life? (Because, it seems obvious to me, the reason "×" vs. "x" in notation "has not been properly discussed before", is because most players wouldn't find that worth discussing – knowing "x" to be normal and best.) Ihardlythinkso (talk) 03:55, 30 May 2012 (UTC)
 * I used to run a chess club, but was the worst player. Although I don't read chess notation much at all, I could see the clear discrepancies between those two aspects of formatting in WP articles and the predominant practice in the authoritative sources. I have a PhD in the psychology of reading, and to me, what most of the major publishers do (including Penguin, if you please) makes sense. WP should follow professional examples. Tony   (talk)  06:10, 30 May 2012 (UTC)
 * Um, Penguin is not anywhere close to being a noted publisher of chess books. (You know that, right?) They may be a "major publisher", but of chess books, certainly not. "Predominant practice in the authoritative sources" sounds mightily impressive, but what does it really mean? (I've asked prev if you could quantify it. It's hard to believe you mean the eight books you listed. What do you mean exactly?) I've checked a few dozen books in my library, publishers Batsford, McKay, Macmillan, Dover, Oxford, Chess Digest, Thinkers' Press, R-H-M, and many others. Mostly it's "x". But other times, a "thin/fine cross" is used (sans detail). Mostly the cross is at least as large as a small-cap letter, sometimes as big as capital "X"! I found only *one* example that used a smallish cross, it wasn't as tiny as WP's "×". For me, I have no problem with the fine, sans detail crosses – they looked okay. But crosses and "x"s occurred unpredictably (both) in different books even within a major publisher (like Batsford; though most of my Batsfords use "x"). If WP did want to consider the thin, sans detail cross, it would have to add a symbol like that to its arsenal. (Reason? Because the current tiny "×" symbol, for gamescores, really sucks!) Cheers. Ihardlythinkso (talk) 10:06, 30 May 2012 (UTC)
 * I find "x" the best, not just because most sources use it, but also because it just seems more logical to the beginner. If the beginner sees "Bxg7", it would be clearer that it's a capture because the "x" implies that something was "xed" on g7 – i.e. a capture took place there.
