According to Chest thisis a mate in 9, with two key moves, but the sulutions are basically equal: PV: Nhxf7+ Qexf7 Nxf5+ Q4xf5 Nxf7+ Qfxf7 Rxf7 Ra2+ Bxa2 Nb6+ Qxb6+ Nf6 Rxh7+ Qxh7 Bf8+ Qg7 Rh8# PV: Ndxf7+ Qexf7 Nxf7+ Qfxf7 Nxf5+ Q4xf5 Rxf7 Ra2+ Bxa2 Nb6+ Qxb6+ Nf6 Rxh7+ Qxh7 Bf8+ Qg7 Rh8# On my K7/600 with 350MB hash this needed 5.6 hours.
