• A Game That Outlasted the Day (4)

  It should be clearly emphasized that the longest chess game of all time can only arise by chance. Any prior agreement between the opponents before the game—such as, "Let’s play the longest game in history today!" – or any such understanding reached during the game, automatically turns them into cheaters, with all the ensuing consequences. Estonian chess expert and trainer, Valery Golubenko, tells us about the struggle to regulate very long theoretical endings.

• A Game That Outlasted the Day (3)

  Two months ago Valery Golubenko played what may well have been one of the longest chess games ever seen, measured by number of moves, under the rather restrictive conditions of modern chess life. At move 88, with queen and b-pawn against queen, Golubenko's opponent held for 37 moves, until he missed an only move, and it was theoretically a mate in 47. | Photo during the game by Chess Club Kaksikodad – from the right, GM Aleksandr Volodin and the chief arbiter Askold Nassar
