It's plydepths i care for. But I do care, that is why I asked you. Of course, if you do not want to post them it is fine. >It's all 5 to 8 ply majority of positions > >You claimed that it was not an easy testset, but positions that solve >at 5 to 8 ply are pretty easy. I do not claim anything, I am sharing the positions that are correct that will be eventually useful for me. Easy is a very relative term. What I tried to do is to eliminate the positions that are "too" easy. Those are the positions that are solved in microseconds, as in WAC, when you cannot even get the time measured accurately. Of course, if you have a top engine in top hardware some positions might fall under a second. Miguel > >I got also 8 ply at world champs 1997. > >It's 4 years later now. > >>Regards, >>Miguel
