What I mean is, there are (approx) 75,484,103,766,819,471,360,000 different pawn formations for all pawns on the board, minus some that are duplicates and not possible to reach, and then plus all of the 8 black pawns vs. 7 white pawns, 7 black pawns vs. 8 white pawns, 7 vs 7, 6 vs 7, 7 vs, 6, etc...and then if you add in the king like you say, that makes for a lot of positions, and I would assume that the pawn hash table is smaller than the normal hash table, so there's no way to store information about all of the pawn formations, and you're probably going to have more collisions than you do in the normal transposition table. It makes me wonder if there are ever errors caused by this. Using bitboards, you could just calculate this stuff on the fly and it will always be correct. Russell
