My analysis that f4 wins was from a human point of view. Do you realize that after f5 and exchanging the e6 pawn the rook on e7 is lost, an important black pieces that could defend against mate on g7 or h7? And I agree Rdd3 wins as easily. My point was that Hiarcs gives already +3 without calculating a node. And I think it is right, blacks position is hopeless. But I'm sure there are similar position where Hiarcs could be dead wrong with this kind of static evaluation. regards Andy
