on my long todo list for my program, the item "pawn hashing" has slowly but steadily floated upwards. now it's on top. so: how large is your pawn hashtable (in # of entries)? how large are your entries? i'm using bitboards, and it seems to me that my entries will be huge, e.g. if i want to save some simple stuff like - passers - connected passers - isolated pawns - doubled pawns - backward pawns - blocked pawns that would be 6x8 = 48 bytes; perhaps times 2 for each side (or i could pop black and white pawns in the same bitboard, and & it with the black/white bitboard to save space). still, that's already 48 bytes and i guess i could save some more stuff if i thought about it a bit longer :-) is that a reasonable size for a pawn hash entry? cheers martin
