I agree that it sounds dangerous without relating it to depth. In my view there are two ways to avoid the problem you meantion: 1) if (some_condition && ply > x) return; 2) if (some_condition && depth < y) return; Where ply is the distance from the root and depth is "remaining depth" In the first one you will find it later on in the game - when the interesting move is closer to the root. Maybe a bit dangerous too but nevertheless possible. In the second one you will find it when the iteration is high enough and if time is limiting the iterations it will eventually be found later on in the game (if it's still there) /Peter
