These results are clearly bad. I waited until movei was lucky to get positive score against Junior5 in the nunn2 match at 3:1 time advantage(at least it was the case with 00_8_174 ponder off when both sides used 16 mbytes hash and movei got 90 minutes against 30 minutes of Junior and 178 is the same as 174 except speed if I have no bugs) before releasing it but I think now that it was simply lucky and I did not do significant improvement in the last year. I know that evaluation is one of the weaknesses of movei relative to the top programs but my opinion is that I do not need to work first about the evaluation but need first to work more about the search and only later to work about improving the evaluation. I believe that it is possible to get 200 elo only by search improvement and first I need to rewrite my alphabeta and I still did not decide exactly how to do it. Uri
