Good morning, i have a good 64bit hash value for each position, xored with side, ep, piece and castling rights. I can say this is good because it's ok for detecting repetitions. I suppose the code to insert informations into the hashtable and to retreive them is ok (thanks to users of this forum). This works fine for a given position : the search goes deep in depth and with a correct PV. Then, if i undo the move and search again, another move is given in PV. I undo the move and seach again and result is different... But if i clear the hash table before each search. It's all right. PV is always the same for a given position. And a good PV. I printed hash values to a file, and depth, eval, hash flags. I can't see anything bad. Have you got any idea where the bug could be ? Regards.
