I don't remember how long it took to find 23.Qxe6+! (maybe 20 minutes) but I had to work out the follow-up 24.Bxg6! before making it. In one of the key variations I had to find Be8! to prevent Black's king from escaping before embarking on the combination. ------------ So, 20 minutes to play 23.Qxe6+ in this position: [D]2r1brk1/p3b2p/2n1p1p1/q2pP3/3P1PQ1/p1NB1NR1/1P4P1/1K1R4 w - - 0 23 And, even more stunning (IMO), is the move right before it -- 22.Nf3! in this position: [D]2r1brk1/p3b2p/2n1p1p1/q2pP3/1p1P1PQ1/P1NB2R1/1P4P1/1K1R2N1 w - - 0 22 Do any engines find either of these moves in a reasonable time and with a reasonable score for White? CM9000 (SKR personality on a P4-2.4) won't find 22.Nf3 at all, preferring f5 with a slightly positive score for White: Time Depth Score Positions Moves 0:00 1/3 0.72 1476 22.axb4 Bxb4 23.Qxe6+ Bf7 0:00 1/4 -0.15 4994 22.axb4 Bxb4 23.Bc2 Nd8 0:00 1/5 -0.24 19170 22.axb4 Bxb4 23.Bc2 Nd8 24.Nge2 0:00 1/5 0.08 86168 22.f5 Nxe5 23.dxe5 bxc3 24.fxg6 c2+ 25.Bxc2 0:01 1/6 0.32 152790 22.f5 exf5 23.Bxf5 Rd8 24.axb4 Bxb4 25.Be6+ Kh8 0:02 1/7 0.45 364661 22.f5 exf5 23.Bxf5 Rd8 24.axb4 Nxb4 25.Be6+ Kh8 26.Rf3 0:04 1/8 0.36 752921 22.f5 exf5 23.Bxf5 Rd8 24.axb4 Nxb4 25.Rf1 Kh8 0:12 1/9 0.11 2017066 22.f5 exf5 23.Bxf5 Rd8 24.axb4 Nxb4 25.Rf3 Kh8 26.Be6 Qa6 0:48 1/10 0.25 8542046 22.f5 exf5 23.Bxf5 Rd8 24.axb4 Nxb4 25.Qh3 Qa6 26.Nge2 Kh8 27.Rh1 1:54 1/11 0.20 20920661 22.f5 exf5 23.Bxf5 Rd8 24.axb4 Nxb4 25.Be6+ Kh8 26.Rf3 Ba4 27.Rc1 Bb5 28.Nge2 As for 23.Qxe6+, here is what The King says: Time Depth Score Positions Moves 0:00 1/4 -1.84 33946 23.Rh1 axb2 24.Qxe6+ Bf7 25.Qh3 Qa1+ 26.Kc2 0:00 1/4 -1.49 57396 23.Qh5 axb2 24.Bxg6 Qa1+ 25.Kc2 0:00 1/5 -2.29 110983 23.Qh5 axb2 24.Bxg6 Qa1+ 25.Kc2 Bxg6+ 26.Rxg6+ Kh8 27.Kd2 Nxd4 28.Nxd4 Rxc3 0:00 1/5 -1.88 147801 23.Qxe6+ Bf7 24.Qd7 axb2 25.Na2 Qa3 26.Bb5 0:01 1/6 -2.83 261327 23.Qxe6+ Bf7 24.Qg4 axb2 25.e6 Qa1+ 26.Kc2 Nxd4+ 27.Nxd4 Rxc3+ 28.Kd2 Qc1+ 29.Ke1 0:03 1/6 -2.80 570718 23.Na2 axb2 24.Bc2 Nb4 25.Bb3 Bd7 26.Ng5 0:04 1/7 -3.28 789459 23.Na2 axb2 24.Bc2 Nb4 25.Bb3 Rc3 26.Qxe6+ Rf7 27.Rxg6+ hxg6 28.Qxg6+ Kf8 0:12 1/7 -2.92 2042265 23.f5 axb2 24.fxg6 Qa1+ 25.Kc2 Nxd4+ 26.Kd2 b1=N+ 27.Nxb1 Nxf3+ 28.Rxf3 Qb2+ 29.Ke1 Qxe5+ 30.Kf1 Rxf3+ 31.gxf3 0:24 1/8 -2.77 4122107 23.f5 axb2 24.fxg6 Qa1+ 25.Kc2 Nxd4+ 26.Kd2 b1=N+ 27.Nxb1 Nxf3+ 28.Rxf3 Qb2+ 29.Ke1 Qxe5+ 30.Kf1 Rxf3+ 31.gxf3 hxg6 32.Bxg6 1:13 1/9 -2.89 12648650 23.f5 Nxe5 24.Nxe5 axb2 25.Na2 Rc1+ 26.Rxc1 Qxa2+ 27.Kxa2 bxc1=Q 28.fxg6 Rf2+ 29.Be2 3:15 1/10 -3.04 35163021 23.f5 exf5 24.Bxf5 Rb8 25.Ne1 Kh8 26.Bc8 Rxb2+ 27.Kc1 Rff2 28.Be6 Nb4 4:35 1/10 -1.51 50598471 23.Qxe6+ Bf7 24.Bxg6 Bxe6 25.Bxh7+ Kh8 26.Rh1 Bh4 27.Rxh4 Rxf4 28.Rxf4 axb2 29.Kxb2 Rb8+ 30.Kc2 Qa1 jm
