It still does not explain the crush that I have. Movei does not use hash tables to prune the tree and it is not supposed to crush when it get bad numbers in the hash. It should only be slower because of bad order of moves but the new numbers that I get with your function when I only change signed to unsidned are almost the same as the old number so I do not believe that the numbers were 0's. I now compare the number in debug and release with your program(I only deleted unsigned because I used numbers that are not unsigned and I do not want to get new problems of translating unsigned to signed. It seems to be the same. In the debug mode I got now 4222981 and 9929068 that are the same as the release mode and I wait for 11697241 and 31903997. Uri
