Just for the record, I've never said that 32 bit keys should be enough if you have 10,000,000 positions ;) You should expect to see collisions around 50,000 positions. > Funny thing was that first I searched >about 5'000'000 nodes with no collisions, then I saw 40 collisions in a short >time, then again no collisions and finally 40 more in a short time. > >Severi Well if they have 5,000,000 positions, then it is not pawns they are hashing. -S.
