Crafty >saw it in 10 seconds on my PII/300 notebook... the score was +.7 for the >move... 1)The fact that programs find a sacrifice does not change the fact that it is a sacrifice. I believe that crafty saw it because of positional reasons(I do not believe that crafty see more than 3 pawns for the piece and if you use material evaluation then black has the advantage because the bad trade principle of crafty say that piece is more than 3 pawns). It is easy for program to see by tactical reasons that white can at least force a draw with perpetual check but not more than it 2)Not all the programs believe that 17.Nf6+ is the best move. Hiarcs7.32 prefers 17.Bb1 g6 18.Nf6+ Uri
