However in 2014, Fide made a relevant change. Although the 50 move was still in effect, it had to be applied by the player on the move. Sometimes, both players wish to continue on endlessly. To correct this, Fide in 2014, said 75 moves is the limit automatically even without players consent. Rule 9.6:
Code: Select all
9.6
If one or both of the following occur(s) then the game is drawn:
the same position has appeared, as in 9.2b, for at least five consecutive alternate moves by each player.
any consecutive series of 75 moves have been completed by each player without the movement of any pawn and without any capture. If the last move resulted in checkmate, that shall take precedence.
My question is whether or not this new rule has been implemented in current chess engines. Right now many chess engines have an option for a strict 50-move draw, and automatically call a draw after 3-fold repetitions. And if the option for the 50-move draw is not checked, is a draw called after 75 moves?
Besides updating to conform to rule 9.6, it would be nice to have a research option that does not impose automatic draws except for stalemates and insufficient material.
