Субъект: Ice age chess - checkmate timing

Сделано для RGroszkiewicz (5. Февраля 2011, 18:53:48)

I would like clarification on the timing of the Ice Age event. It will affect my strategy in an actual game.

Assume Black can checkmate White immediately on the 40th move. The checkmate is caused by a Rook or Queen several squares away from the White King.

White would be checkmated after Black moves, but only before the Ice Age event. Once the Ice Age event occurs, those empty square are filled with ice, so the White King is not checkmated.

Is the game over? Or does White get to keep playing?
