Talk:List of chess openings named after places

Queen's Gambit Declined
I know there's a Westphalia Defence, Carlsbad Variation and Manhattan Variation in the Queen's Gambit Declined, but I don't know what the move orders are (they're all old names, but still used). Also the New York System against the Reti Opening. Anyone know what they are? youngvalter 23:19, 2 May 2007 (UTC)
 * The Oxford Companion to Chess says that the Westphalia and the Manhattan are the same, and that the Carlsbad is a variation of the Slav Defense. I added them. Quale 07:23, 16 May 2007 (UTC)

Two suggestions
In the UK we have the "Clarendon Court Defence", 1.d4 c5 2.d5 f5, invented by GM Jon Levitt; is this just a UK phenomenon or has it a wider appeal? It is named after the block of flats he lived in at the time. See his website or Google it for a fuller explanation. The "Peruvian Variation" of the QGD is mentioned here, but isn't this better known as the "Dutch-Peruvian Gambit"? I believe the 2 main lines were pioneered by Prins and Canal, hence the two nationalities in the title. Either way, it qualifies for the list. Brittle heaven (talk) 01:15, 9 December 2007 (UTC)

Notability
It would be my suggestion that some indication of why the location is notable in naming each of the openings listed here. For example (fictitious): "The Houston Opening was first used with great success by HyperCapitalist in the 2009 Chess Open held in Houston, Texas." Some openings here have no indication in this article or in the linked article that the place name is even commonly used or where the location is -- for example, the Abbazia Defense of the King's Gambit. Where is Abbazia? What source mentions the Abbazia Defense? Why is this line called the Abbazia Defense? HyperCapitalist (talk) 01:34, 28 October 2009 (UTC)
 * That's just nitpicking. When this suggestion is implemented, you will want to know who was the opponent of HyperCapitalist. Then you will want to know what happened to his opponent when he was stunned by the new opening... In its current form the list meets the minimum requirements. --MrsHudson (talk) 05:50, 28 October 2009 (UTC)
 * The name comes from a tournament, Abbazia 1912. Abbazia is now the city of Opatija in former Yugoslavia, now Croatia. SunCreator (talk) 01:45, 28 October 2009 (UTC)

Zinnowitz Variation
According to the Oxford Companion to Chess, there is also a Zinnowitz Variation of the King's Indian Defence, "played in the tournament at Zinnowitz in 1966". --Uwe (talk) 13:51, 5 May 2013 (UTC)
