I'll take WChess2000 as black. Which white player do you think is best to defend the white position? I'd guess Genius, do you have another suggestion? Hiarcs? >I did not say that white is better but it is not clear to me that black is >better. Let me say: I'd prefer playing black. :-) >Junior5.4 evaluate the position after 21.Kd1 as a small advantage for white >after 30 minutes(0.03 pawn) and suggested Nb6. 1) I don't mind what Junior >5.0 says because right now it is obviously a beta and may contain some bugs 2) even this small advantage confesses compensation for white is a piece up and should, if sound, have an eval of clearly over +1.50 >Junior suggested 21.Kd1 but changes its mind and after 1 hour it suggested >21.Kf1 with an evaluation of a small advantage for white(I do not remember the >exact evaluation but it was close to 0.1 or 0.2 pawns for white).
