Konu: Re: Ice age chess - checkmate timing

nabla:
I'm not sure your definition of checkmate is correct. Fide's website says:

The objective of each player is to place the opponent’s king ‘under attack’ in such a way that the opponent has no legal move. The player who achieves this goal is said to have ‘checkmated’ the opponent’s king and to have won the game. Leaving one’s own king under attack, exposing one’s own king to attack and also ’capturing’ the opponent’s king are not allowed. The opponent whose king has been checkmated has lost the game.

The question in ice age chess would be does the definition of legal move apply at the time of black's 40th or white's 41st? Clearly not an issue in standard chess as the board is the same. I would vote for on black's 40th for symmetry.
