I looked up Malakhov. Although little known outside of Russia, he is now the positive side of 2700. He has referred to the incident in interviews, in which he says he was too shocked to think straight and make a protest. He was also a young player against an established player who was also politically powerful, being a FIDE Vice President at the time. Much the same reaction was given by Judit Polgar although Kasparov's Linares take back needed video replay to establish whether he let go of the piece for a micro second.When he realised that his move didnâ€™t correspond to the notation, Malakhov gave him permission to take back his move, which permission was freely and spontaneously given. Malakhov signed the scorecards, there were no appeals, and according to the rules of chess, THAT IS THAT!
But if you fail to play the move you intend, even if written down first as was legal at the time, you might be allowed to take it back in a "friendly" game, but not in any sort of competition, even a club championship. You just shouldn't even ask.
