CM_SKR, on the other hand, sees in five seconds that 22.Nxd5 Qxd5+ 23.Ke2 is better for White, and leads to a draw: Time Depth Score Positions Moves 0:00 1/3 -0.10 994 17.Rxf2 Rxf2 18.Kxf2 Qh4+ 19.Kg1 Nxc2 0:00 1/4 -0.12 3053 17.Rxf2 Rxf2 18.Kxf2 Qh4+ 19.Kg1 Nxc2 20.g3 0:00 1/5 0.81 13790 17.Rxf2 Rxf2 18.Kxf2 Qf6+ 19.Ke2 Qg5 20.axb4 Qxg2+ 21.Kd3 Bxd5 22.Nxd5 Qxd5+ 23.Ke2 0:00 1/6 0.13 42227 17.Rxf2 Rxf2 18.Kxf2 Qf6+ 19.Kg1 Rf8 20.Ne4 Qh4 21.axb4 Qxe4 0:00 1/7 0.26 127831 17.Rxf2 Rxf2 18.Kxf2 Qf6+ 19.Ke2 Bc8 20.Kd2 Qf2+ 21.Qe2 Qxe2+ 22.Kxe2 Nxc2 23.Rb1 0:01 1/8 1.06 334779 17.Rxf2 Rxf2 18.Kxf2 Qf6+ 19.Kg1 Rf8 20.h3 Qf2+ 21.Kh2 Nxc2 22.Ne4 Nxa1 23.Nxf2 Rxf2 0:02 1/9 1.22 712749 17.Rxf2 Rxf2 18.Kxf2 Qf6+ 19.Kg1 Rf8 20.h3 Qf2+ 21.Kh2 Nxc2 22.Ne4 Nxa1 23.Nxf2 Rxf2 24.e4 a5 0:05 1/10 0.00 1873375 17.Rxf2 Rxf2 18.Kxf2 Qf6+ 19.Ke2 Qg5 20.axb4 Qxg2+ 21.Kd3 Bxd5 22.Nxd5 Qxd5+ 23.Ke2 Qg2+ 24.Kd3 Qd5+ 0:11 1/11 0.00 3920292 17.Rxf2 Rxf2 18.Kxf2 Qf6+ 19.Ke2 Qg5 20.axb4 Qxg2+ 21.Kd3 Bxd5 22.Nxd5 Qxd5+ 23.Ke2 Qg2+ 24.Kd3 Qd5+ 0:25 1/12 0.00 8580620 17.Rxf2 Rxf2 18.Kxf2 Qf6+ 19.Ke2 Qg5 20.axb4 Qxg2+ 21.Kd3 Bxd5 22.Nxd5 Qxd5+ 23.Ke2 Qg2+ 24.Kd3 Qd5+ 0:59 1/13 0.00 20526203 17.Rxf2 Rxf2 18.Kxf2 Qf6+ 19.Ke2 Qg5 20.axb4 Qxg2+ 21.Kd3 Bxd5 22.Nxd5 Qxd5+ 23.Ke2 Qg2+ 24.Kd3 Qd5+ jm
