Thanks for your opinion I am not sure at all if 317 is an improvement relative to previous version and one of the possible reasons for the bad result is some bad learning that push it after some losses to use uncommon lines like 1.b3 or 1.d4 c5(the fact that it could beat Quark 4-0 with these bad lines encourag it to repeat these lines in later games and later after losing with b3 it started to try 1.b4 against ufim and got 2 draws). I also discovered some bug in my pruning in 317 but unfortunately first tries to fix the bug made it weaker in test suites and I even did not try it in games. I am not sure if the latest fix is better but I kept it. another difference between 325 is that I added pruning in the qsearch based on SEE that do it slightly faster and probably slightly better. I did not touch the evaluation of 317 in the latest version that compete in the promotion tournament. result after 54 games at 3 minutes/40 moves on A3000 was 29-25 for 325 against 317(of course it proves nothing but I have no computer time to use for testing because I prefer to use computer time for other things like correspondence games). Note that I think to rewrite movei but I decided to try to make some improvement before the promotion tournament. Uri
