The hashing is no real problem (most times :-) ). Real problems, I got with hashing and extensions and pruning together. Then Null Move, mate scores and Draw (repetition). The Null moves and mate scores now work. Draw scores never come into my hashtables! The first problem with extension, pruning and hashing is a neverending and unsolvable thing. But now (after 1 year, most time changing something with hashing) it works. (not perfect, but fine...) Next problem is the evaluation with hashing. If you have some scores, depending on move number or something "previous", you also stuff shit in the Hash..... So I am proud to nearly never clean the hashtables, my hashing must be "supercorrect" or Inmichess eats the hash shit.... Hashing, the neverending story......... Werner
