Do you define >this as a real sacrifice? If the program can see the mate or can see material that it get I define it as a combination and not as a real sacrifice The test if it is a real sacrifice can be done by a materialistic program with good search rules(positional scores always lower than 0.5 pawn so we can know the material score based on the score of the program). If the materialistic program can only see that the sacrifice is losing material even after a long search then it is clearly a real sacrifice. Uri
