I am still trying to resolve this problem. Following is a Crafty output announcing ce=-32759 for the following example after a 5 minute analysis. rnb2r1k/8/2pqp1Q1/pp2NpP1/3P4/b2B2P1/1PPBK3/R7 b - - acd 11; acn 7676585; acs 31; ce -32759; pv Qd5 Nf3 Qxf3+ Kxf3 Rf7 Rh1+ Rh7 Rxh7#; [D]rnb2r1k/8/2pqp1Q1/pp2NpP1/3P4/b2B2P1/1PPBK3/R7 b - - Do you agree that the analysis is right for this first position? Now if we keep the exact same position but place the black queen on d7 instead of d6 from the previous position the analysis takes alot longer but still should have the same mate as above since the queen on d7 can still go to d5. [D]rnb2r1k/3q4/2p1p1Q1/pp2NpP1/3P4/b2B2P1/1PPBK3/R7 b - - Can someone run these 2 positions and provide me with the results ie ce, pv, acd, acn and how long it took to find the mates in both positions please. I had posted several of these earlier but trying to see if in fact there is an error on my part or if the chess engines are just having a much more difficult time in finding the 2 solutions. I would think since in both cases the black queen in both positions can reach the d5 square which should be a mate. Thanks Les
