>I'm not sure, but my gut feeling is that every roll above 3 and maybe even equal to 3 is an immediate checkmate or at the very least a crushing advantage. Like, rolling a 4 on the first move wins the game, rolling a 3 wins the queen, ... that much tempo is devastating. That advantage is held in check, so to speak, by the check limited turns. Once a piece has put an opponent in check, it can't move again. Other pieces cannot put the opponent in check on the same move. That still creates the possibility of checkmate in one turn, but remember that the opponent will likely also get multiple moves to get out of the situation. Assuming that the in-check player can use all of their moves to get out of check, they might get 3 or 4 moves with which they can wipe out the advantage gained by the other player on the previous move. Of course, if the in-check player only happens to get one move then it is probably over. Basically, this injects a significant level of chance into gameplay and it speeds up the game. Its really a different game. The more I think about it the more interesting it becomes. To make it more even handed and less dependent upon chance, it could be done with only 2-3-4 move turns. Being allowed only a single move after an opponent had 4 moves is a disaster. Or maybe a limit on the delta between move counts for successive turns.
