Seeing the sacrifices is not the problem and I guess that every program will find them if you increase the value of the queen by one pawn and will not solve them if you reduce the value of the queen by one pawn. The question is if the sacrifices are winning. Rebel did not see a win for white if you look at the score(0.64 for white) The score for Rd2 art depth 7 was 0.19 against white so the change in the score was less than one pawn. Uri
