Genius is all the time the best program for mate solution. You did good choice by trying to solve just on it. Genius is very permissive, stable and exact. This position look more like exception. Do your Genius 3 have some problem with graphics? My Genius 2 had. Second very stable and permissive program is Chessmaster. At least 50% of all chess programs I expect to hang on the position like this. Tried it on not mate solver, 8 plys brute force search. Move came the same as for the mate. White pawn promoted to queen from g7 to g8. Leonid.
