Bob, perhaps sometimes you pay too little attention to some comments. Vincent mentioned, that he used Crafty without TBs. PVs he has shown seem to indicate, that Crafty's eval misevaluates some KPK positions as win, when they are draw. Vincent said exactly this in a former post. I almost never get such bug reports for my engine. I'd be very happy for them. I myself reported clear Crafty problems in the past. Answers were a bit like: "In 99.9% of the cases 0.0 eval for KRB-KR is correct". It is not the case. More subtle problems were pointed out. I think, only after a really obvious problem in Peter Bergers Junior-Crafty time/hardware-odds games, where the same problem showed, Bob did some fix. Mike, Vincent clearly has said, that he tried without TBs. Of course, with correct TBs the "c6-problem" will vanish. If Bob does not accept CB-native Crafty, he should not allow it, instead of just using it as an excuse. I guess, Mathias Feist is creating the CB-native engines. He is most probably doing a very good job with it. If there is something strange there, it might be interesting for those, who try to improve Crafty. Regards, Dieter
