User:Dlbbld/Seventy-five-move rule

In chess, the seventy-five-move rule states that the game ends immediately with a draw if no capture has been made and no pawn has been moved in the last seventy-five moves; unless the last move was a checkmate, in which case the checkmate is valid. The rule is related by definition to the fifty-move rule in as such it looks at a series of consecutive moves without or pawn move. The arbiter must enforce the draw in such a case. The rule also exists in the USCF Rules Of Chess with the difference that the draw is on request of the tournament directory only. Chess software does not support the rule very well. According to IA Steward Reuben, the rule was introduced not to prolong tournament games on a tight schedule. The seventy-five-move rule and independently, the at the same time added fivefold repetition rule, causes that each chess game ends in a finite number of moves..

Statement of the rule
The relevant part of the official FIDE Laws of Chess is quoted below: "9.6 If one or both of the following occur(s) then the game is drawn:
 * 9.6.2 any series of at least 75 moves have been made by each player without the movement of any pawn and without any capture. If the last move resulted in checkmate, that shall take precedence."

Example
An example of a game terminated after exactly seventy-five moves without capture and pawn move by each player is the Blitz game Topalov vs Nakamura, 2016.

History of the rule
This rule became effective on 1 July 2014 together with the fivefold repetition rule. The introduction of the seventy-five-move rule did not affect the existing fifty-move rule.
