(2) is common and is why the >replacement strategy is so important. I defined collision somewhere in this thread but it is the same as (1): from code of DarkSight which is comparable with next.c in Crafty /********************/ case HASH_MOVE: if( a tt_move is provided ) { tree->stats.hashkey_requests++; if( provided tt_move is valid move ) return tt_move; else tree->stats.hashkey_collisions++; } /********************/ Or is there something wrong?
