Neurosis 1.4(next version) on slow pIII-550 with 64MB hash. g6 is a draw, and later it finds Rf6 to be winning. It's probably atleast a mate in 7 or more with not much prior checks in the main line. What is the solution the other programs gave you tested? Other programs will do better but I just wanted to let Neurosis search on a position for a longer time.
