Furthermore I posted the solution find by Gandalf 4.32h some days ago: Analysis by Gandalf 4.32h: 1.Lf2 dxe5 µ (-0.96) Tiefe: 2 00:00:00 1.exd6 µ (-0.94) Tiefe: 2 00:00:00 1.exd6 Dxd6 2.c5 ² (0.38) Tiefe: 2 00:00:00 1.exd6 Df6 2.Lf2 Sxd6 = (0.00) Tiefe: 3 00:00:00 1.exd6 Df6 2.Lf2 Sxd6 = (0.00) Tiefe: 4 00:00:00 1.Lxh5 = (0.01) Tiefe: 4 00:00:00 1.Lxh5 fxg3 2.Sxg6 De6 3.Sxf8+ Sxf8 ± (0.84) Tiefe: 4 00:00:00 1.Lxh5 gxh5 2.Sxf5 De6 3.Sxh6+ Kxh6 4.Lxf4+ Kg7 ± (0.97) Tiefe: 5 00:00:00 54kN 1.Lxh5 Sh8 2.Sxg6 Sxg6 3.Lxg6+ Kxg6 4.exd6 Dxd6 5.Lh4 ² (0.38) Tiefe: 6 00:00:00 181kN 1.Lxh5 Sh8 2.Lf2 dxe5 3.dxe5 gxh5 4.Sxf5 De6 = (-0.17) Tiefe: 7 00:00:01 473kN 1.Lxh5 Sh8 2.Lf2 dxe5 3.dxe5 gxh5 4.Sxf5 De6 5.Sd4+ Dg6 = (0.04) Tiefe: 8 00:00:05 1300kN 1.exd6 = (0.06) Tiefe: 8 00:00:06 1950kN 1.Lxh5 Sh8 2.Lf2 dxe5 3.dxe5 Sxe5 4.Sf3 Sxf3+ 5.Lxf3 Le6 = (0.04) Tiefe: 9 00:00:13 4400kN 1.exd6 = (0.06) Tiefe: 9 00:00:16 4950kN 1.exd6 Dxd6 2.c5 Dc7 3.Lxh5 gxh5 4.Dxf5+ Kh8 5.Sg6+ Kg8 = (0.09) Tiefe: 9 00:00:19 6450kN 1.Sxg6 = (0.11) Tiefe: 9 00:00:22 7650kN 1.Sxg6 Kxg6 2.Dxf5+ Kg7 3.Ld3 Th8 4.Lxf4 Lxf4 5.Dxf4 dxe5 = (0.22) Tiefe: 9 00:00:27 9300kN 1.Sxg6 Kxg6 2.Dxf5+ Kg7 3.Ld3 Th8 4.Dg6+ Kf8 5.e6 fxg3 = (-0.04) Tiefe: 10 00:00:56 20850kN 1.exd6 = (-0.03) Tiefe: 10 00:00:58 21550kN 1.exd6 Dxd6 2.Lf2 Sf6 3.d5 cxd5 4.Sxd5 Sxd5 5.Txd5 Dc6 = (0.16) Tiefe: 10 00:01:20 28300kN 1.exd6 Dxd6 2.c5 Dc7 3.Lxh5 gxh5 4.Dxf5+ Kg8 5.Dg6+ Kh8 = (0.16) Tiefe: 11 00:02:42 56500kN 1.Sxg6 = (0.17) Tiefe: 11 00:02:47 58100kN 1.Sxg6 Kxg6 2.Dxf5+ Kg7 3.Ld3 Th8 4.Dg6+ Kf8 5.e6 fxg3 ² (0.68) Tiefe: 11 00:04:13 92200kN (Utzinger, MyTown 30.11.2001)
