In a last round tie between 2 players fighting for top seed in a competition, here is what happened.
White had 18 seconds on his clock and black had 26 seconds. Black was winning. At move 56, black made a pawn push which exposed his king to a check by a dark square bishop, thus making the pawn push an illegal move. White did not take note so he raised the bishop and was about to play then he saw that the king was in check, so before he could call 'illegal' black quickly called the 'touch move rule'. Thus implying that white had to move the bishop. According to FIDE rules which call should supersede: Black's 'touch move' or white's 'illegal move'?
