Video film stills confirmed that Kasparov's hand had quit the knight for about a quarter of a second.
What made 1994 a memorable year for chess? Certainly it had its share of controversial incidents, led by the touch-move dispute in which Garry Kasparov took back a move against Judit Polgar.
Mr. Kasparov picked up his knight at d7 and placed it on c5. 'Touch move' requires a player to move a touched piece, but the move is not over until the hand leaves the piece. Seeing that 37.Bb7–c6 would be bad for Black, Mr. Kasparov instead put the knight on f8. However, the way Miss Polgár saw it, Mr. Kasparov's hand did leave the piece on c5. Accounts diverge from there. We do know that Spanish TV recorded the game and that there were several spectators, some of whom thought that Mr. Kasparov removed his hand from the knight at c5.
