Note that latest Movei only see mate in 32 from the original position and it does not search for shorter mate It's line is 27.Neg4+ Kf5 28.Nh6+ Ke5 29.Nf7+ Kf5 30.Nd6+ Ke5 31.Ng4+ kd5 32.c4# Fritz gui for some reason do not understand movei's mate score and when movei writes 32764 it translates it to mate in 1 and when it writes 32766 it translate it to mate in 0. It has no problem to understand movei's score when it writes mate against itself. I wonder if there is some bug in the chessbase gui that translate socre of winboard engines to mate score wrong. Uri
