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.
