I think Shredder find the same solution but with transposition ( 1.Rxe7 fxg5 2.e5 Na6 instead of e5 fxg5 Rxe7! Na6) after 3:02 on an AMD barton@3000+ rn1r2k1/pR2p2p/5pp1/6B1/3bP3/5B2/q4PPP/2Q2RK1 w - - 0 1 Analysis by Shredder 8: ... 1.Txe7 fxg5 2.e5 Ca6 3.Fxa8 Txa8 4.Tb7 Fxe5 5.Dxg5 = (0.01) Profondeur: 8/20 00:00:00 51kN 1.Txe7 fxg5 2.e5 Ca6 3.Fxa8 Fxf2+ 4.Txf2 Td1+ 5.Dxd1 Dxf2+ 6.Rxf2 = (0.01) Profondeur: 8/20 00:00:00 74kN 1.Fd1 Rh8 2.Fe3 Fxe3 3.Dxe3 Cc6 4.Fb3 Dd2 5.Dc5 = (0.02) Profondeur: 8/20 00:00:00 85kN 1.Fd1 Rh8 2.Fe3 Fxe3 3.Dxe3 Cc6 4.Fb3 Dd2 5.Dc5 = (0.02) Profondeur: 8/20 00:00:00 85kN 1.Fd1 Rh8 2.Fb3 De2 3.Txe7 fxg5 4.Dc7 Cd7 5.Txd7 Txd7 6.Dxd7 Dxe4 = (-0.10) Profondeur: 9/20 00:00:00 155kN 1.Fe3 De6 2.Fxd4 Txd4 3.e5 a5 4.exf6 Dxf6 5.Dc8+ Df8 6.Dc3 = (-0.09) Profondeur: 9/22 00:00:00 274kN 1.Fe3 Fxe3 2.Dxe3 De6 3.e5 Tc8 4.Da3 Cd7 5.exf6 exf6 6.Td1 = (0.18) Profondeur: 9/22 00:00:00 329kN 1.Fe3 Fxe3 2.Dxe3 Cc6 3.e5 Cxe5 4.Txe7 Te8 5.Txe8+ Txe8 6.Fd5+ Dxd5 7.f4 Rh8 8.fxe5 = (-0.07) Profondeur: 10/25 00:00:01 468kN 1.Fe3 Fxe3 2.Dxe3 Cc6 3.Tc1 Tab8 4.Txb8 Txb8 5.Txc6 Dxf2+ 6.Rxf2 = (-0.07) Profondeur: 10/25 00:00:01 520kN 1.Fe3 Fxe3 2.Dxe3 Cc6 3.Fd1 Dd2 4.Fb3+ Rh8 5.Fd5 Dxe3 6.fxe3 Tdc8 7.Tc1 Ce5 8.Txc8+ Txc8 9.Txa7 = (-0.21) Profondeur: 11/24 00:00:02 927kN 1.Fd1 Rh8 2.Fb3 Da6 3.Txe7 Cd7 4.Te6 Da1 5.Dxa1 Fxa1 = (-0.20) Profondeur: 11/24 00:00:03 1066kN 1.Fd1 Rh8 2.Fb3 De2 3.Txe7 fxg5 4.Dc7 Cd7 5.Txd7 Txd7 6.Dxd7 Dxe4 7.Df7 = (0.05) Profondeur: 11/24 00:00:03 1177kN 1.Fd1 Rh8 2.Fb3 Db2 3.Dxb2 Fxb2 4.Fd5 Fd4 5.Txe7 Txd5 6.exd5 fxg5 7.Td1 Fg7 = (0.14) Profondeur: 12/26 00:00:05 1733kN 1.Fd1 Fb6 2.Fh6 Rf7 3.Fe3 De6 4.Fxb6 axb6 5.Dh6 Rg8 6.Fb3 Dxb3 7.Txe7 Td3 8.Dxh7+ Rf8 ² (0.36) Profondeur: 13/28 00:00:10 3539kN 1.Fd1 Rh8 2.Fb3 Da5 3.Fe3 Dc3 4.Fxd4 Dxd4 5.Td1 a5 ² (0.60) Profondeur: 14/40 00:00:19 6749kN 1.Fd1 Rh8 2.Fb3 Da5 3.Fh6 Dc5 4.Dd2 Cd7 5.Tc1 Dd6 6.Dg5 fxg5 7.Txa7 Txa7 ² (0.36) Profondeur: 15/32 00:00:28 10072kN 1.Fd1 Rh8 2.Fb3 Da5 3.Fh6 Dc5 4.Dd2 Cd7 5.Tc1 Dd6 6.Fd5 Cc5 7.Tbb1 Fxf2+ 8.Rxf2 Df4+ 9.Fxf4 ² (0.61) Profondeur: 16/34 00:00:54 19039kN 1.Fd1 Rh8 2.Fb3 De2 3.Txe7 fxg5 4.Dc7 Cd7 5.Txd7 Txd7 6.Dxd7 Dxe4 7.Fd5 Dd3 8.Dxa7 Txa7 9.Fe4 ² (0.61) Profondeur: 16/34 00:00:59 20899kN 1.Fd1 Rh8 2.Fb3 De2 3.Txe7 fxg5 4.Dc7 Cd7 5.Txd7 Txd7 6.Dxd7 Dxe4 7.Fd5 Dd3 8.Dxa7 Txa7 9.Fe4 Dxe4 ² (0.36) Profondeur: 17/38 00:01:38 34829kN 1.Fd1 Rh8 2.Fb3 De2 3.Txe7 fxg5 4.Fd5 Ca6 5.Fc4 Db2 6.Dxb2 Fxb2 7.Fxa6 Td6 8.Tb7 Fg7 9.Fc4 a5 10.Te1 = (0.02) Profondeur: 17/40 00:02:01 43377kN 1.Txe7 fxg5 2.e5 Ca6 3.Dxg5 Tab8 4.Dh4 h6 5.De4 Rf8 6.Dxg6 Fxf2+ 7.Txf2 Tb2 8.Txa7 Tb6 = (0.03) Profondeur: 17/45 00:03:02 66228kN 1.Txe7 fxg5 2.e5 Ca6 3.Dxg5 Tab8 4.Dh4 h6 5.De4 Rf8 6.Dxg6 Fxf2+ 7.Txf2 Tb2 8.Txa7 Tb6 9.Txa2 Td7 10.Dxb6 ² (0.38) Profondeur: 17/46 00:03:29 76831kN 1.Txe7 fxg5 2.e5 Ca6 3.Dxg5 Tab8 4.Dh4 Dxf2+ 5.Dxf2 Fxf2+ 6.Txf2 Cb4 7.e6 Tb6 8.Te2 a5 9.Ta7 Te8 10.e7 Rf7 11.Tf2 Tf6 12.Tf1 ² (0.45) Profondeur: 17/51 00:06:24 137729kN 1.Txe7 fxg5 2.e5 Ca6 3.Dxg5 Tab8 4.Dh4 Dxf2+ 5.Dxf2 Fxf2+ 6.Rxf2 Cc5 7.Ta1 a6 8.Rg3 Tb4 9.Tc7 Tc4 10.Ta7 h5 11.h4 Rf8 12.Fe2 Tc3+ 13.Ff3 ² (0.44) Profondeur: 18/53 00:10:34 226518kN
