I suggest that you give Tao Rg8 and analyze the position after Rg8. Movei does not see mate after Rg8 but can see a big advantage for white(10.37 pawns at depth 10 and fail low at depth 11) Rd1 wins a queen for a rook when Rg8 wins a queen for nothing. The only line is Rg8 f5 g5+ and now yace says Kh5 mate in 8 against itself. When I go backward yace can see that Rg8 is a mate in 10. 1.Rg8 f5 2.g5+ Kh5 3.Qd6 Qh1+ 4.Kxh1 Kh4 5.Kh2 Rb7 6.Qd2 Rb1 7.Qg2 Rb2 8.Qxb2 Kh5 9.Kh1 +- (#10) Depth: 1 00:00:00 Uri
