I have now no games to play in correspondence chess except one game when I am clearly winning(yace says 13.22 pawns advantage for me after a long search) and my computer time is to analyze my games in order to give comments. 3 of my wins are going to be published. I am interested to know the losing material moves for comments. c3 is losing because of a complicated tactics. I gave the main lines that computer programs need to see in my first post when I posted all the game. Yace also learned that it is bad and got evaluation of 1.77 pawns against itself after learning. I gave it to analyze every position in the lines that were posted for at least few minutes and in some cases even for few hours and I started at the end of the lines and finished in the beginning. I believe that Diep is going to fail low on c3 if you give it a long search because white is clearly losing in the position that was posted. yace said 2.02 against white after c3 Bxa3(it learned that 26.bxa3 Qa5 is winning for black thanks to complicated tactics and it also learned that 26.Nf3 is bad so it needs a long time to find that other alternatives are even worse in order to find 26.Nf3) Luba kristol - Uri blass [D]2rr2k1/5pp1/1q2p2p/4n3/p2NP1P1/bpP1B2P/1P1RQ3/K2R4 w - - 0 1 Analysis by Yace 0.99.56: 26.bxa3 Qa5 27.Rc1 Rxc3 -+ (-2.27) Depth: 1 00:00:00 26.Nxb3 Rxd2 27.Nxd2 Bxb2+ 28.Ka2 -+ (-1.91) Depth: 1 00:00:00 26.Nxe6 Rxd2 27.Qxd2 Bxb2+ 28.Kxb2 Qxe6 -+ (-1.76) Depth: 1 00:00:00 26.Bxh6 Bxb2+ 27.Kxb2 gxh6 -+ (-1.44) Depth: 1 00:00:00 26.Rg1 µ (-1.36) Depth: 1 00:00:00 26.Nb5 µ (-1.24) Depth: 1 00:00:00 26.Rf1 µ (-1.11) Depth: 1 00:00:00 26.Qb5 µ (-1.06) Depth: 1 00:00:00 26.Qb5 Qxb5 µ (-0.97) Depth: 2 00:00:00 26.g5 Be7 27.gxh6 Rxc3 28.bxc3 Qxd4 µ (-0.94) Depth: 2 00:00:00 26.g5 Nc4 27.bxa3 Nxd2 28.Bxd2 hxg5 µ (-0.81) Depth: 2 00:00:00 26.g5 Nc4 27.bxa3 Nxd2 28.Bxd2 hxg5 µ (-0.81) Depth: 3 00:00:00 26.g5 Nc4 27.bxa3 b2+ 28.Rxb2 Qxd4 µ (-0.81) Depth: 4 00:00:00 26.g5 Nc4 27.bxa3 Nxa3 µ (-0.81) Depth: 5 00:00:00 55kN 26.g5 Nc4 27.bxa3 Nxe3 28.Qxe3 hxg5 µ (-0.81) Depth: 6 00:00:00 137kN 26.g5 Nc4 27.bxa3 Nxe3 28.Qxe3 Rxd4 29.cxd4 hxg5 µ (-0.81) Depth: 7 00:00:01 533kN 26.g5 Nc4 27.bxa3 e5 28.Nxb3 Rxd2 29.Qg4 Rxd1+ 30.Qxd1 µ (-1.21) Depth: 8 00:00:05 1732kN 26.g5 Nc4 27.bxa3 e5 28.Rd3 exd4 29.Bc1 Ne3 -+ (-1.50) Depth: 8 00:00:07 2301kN 26.Nf5 Rxd2 27.Rxd2 Qb7 28.Nxg7 Kxg7 29.bxa3 Qxe4 30.Bxh6+ Kh7 -+ (-1.49) Depth: 8 00:00:24 7336kN 26.Nf5 Rxd2 27.Rxd2 Qa5 28.Nd6 Rxc3 29.Kb1 Bxd6 30.bxc3 µ (-1.38) Depth: 8 00:00:25 7959kN 26.Bf4 Bxb2+ 27.Rxb2 Nc4 28.Bc1 Nxb2 29.Bxb2 Rxd4 30.cxd4 Qxd4 µ (-1.37) Depth: 8 00:00:33 10181kN 26.Bf4 Bxb2+ 27.Rxb2 Nc4 28.Bc1 Nxb2 29.Bxb2 Qa5 30.Kb1 e5 31.Nf5 Rxd1+ 32.Qxd1 Rxc3 33.Bxc3 Qxc3 µ (-1.26) Depth: 8 00:00:34 10493kN 26.Bf2 Qa5 27.Bh4 g5 28.Be1 Rxd4 29.cxd4 Nc4 µ (-1.25) Depth: 8 00:00:36 11115kN 26.Bf2 Nc4 27.bxa3 Nxd2 28.Qxd2 e5 29.Kb1 exd4 30.Qxd4 µ (-1.26) Depth: 8 00:00:38 11735kN 26.Bf4 Bxb2+ 27.Rxb2 Nc4 28.Bc1 Nxb2 29.Bxb2 Qa5 30.Kb1 e5 31.Nf5 Rxd1+ 32.Qxd1 Rxc3 33.Bxc3 Qxc3 µ (-1.26) Depth: 8 00:00:38 11735kN 26.Bf4 Bxb2+ 27.Rxb2 Nc4 28.Bc1 Nxb2 29.Bxb2 Qc5 30.Nf5 exf5 31.gxf5 -+ (-1.66) Depth: 9 00:00:45 13901kN 26.Bf4 Bxb2+ 27.Rxb2 Nc4 28.Bc1 Nd2 -+ (-1.66) Depth: 9 00:00:49 15256kN 26.g5 Nc4 27.bxa3 e5 28.Rd3 Nxe3 29.Qxe3 b2+ 30.Kb1 Rc7 -+ (-1.65) Depth: 9 00:00:54 16932kN 26.g5 Bxb2+ 27.Rxb2 Rxc3 28.gxh6 a3 29.Rxb3 Rxb3 30.Nxb3 Rxd1+ 31.Qxd1 Qxe3 32.Qd8+ Kh7 33.hxg7 -+ (-1.58) Depth: 9 00:01:19 24355kN 26.Re1 Bc5 27.Nf3 Rxd2 28.Nxd2 Bxe3 29.Qxe3 a3 30.bxa3 Qc7 -+ (-1.57) Depth: 9 00:02:01 37831kN 26.Re1 Qa5 27.Rc1 Nc4 28.bxa3 Qc5 29.Kb1 Nxd2+ 30.Bxd2 Qxa3 -+ (-1.55) Depth: 9 00:02:05 39037kN 26.Re1 Qa5 27.Rc1 Bd6 28.Kb1 Nc4 29.Rd3 e5 30.Nf5 a3 -+ (-1.49) Depth: 10 00:02:38 49165kN 26.g5 Bxb2+ 27.Rxb2 Rxc3 28.g6 Nc4 29.gxf7+ Kxf7 30.Bg1 Nxb2 31.Rf1+ Rf3 32.Nxf3 a3 -+ (-1.48) Depth: 10 00:03:09 58264kN 26.g5 Bxb2+ 27.Rxb2 Rxc3 28.g6 Nxg6 29.Rd3 Rxd3 30.Qxd3 e5 31.Qb5 Qxb5 32.Nxb5 -+ (-1.41) Depth: 10 00:03:44 68615kN 26.g5 Bxb2+ 27.Rxb2 Rxc3 28.g6 Nxg6 29.Rd3 Rxd3 30.Qxd3 e5 31.Qb5 Qxb5 32.Nxb3 -+ (-1.81) Depth: 11 00:06:31 119328kN 26.g5 Bxb2+ 27.Rxb2 Rxc3 28.Qe1 Qc5 29.g6 Qa3+ 30.Kb1 Rxe3 31.gxf7+ Kh7 32.Qxe3 Qxb2+ 33.Kxb2 Nc4+ -+ (-2.23) Depth: 11 00:09:07 168638kN 26.Re1 Qa5 27.Rc1 Bd6 28.Kb1 Nc4 29.Rd3 e5 30.Nf5 Kh7 -+ (-2.22) Depth: 11 00:09:34 177285kN 26.Re1 Qa5 27.g5 Nc4 28.gxh6 Nxd2 29.Qxd2 e5 30.bxa3 exd4 31.Bxd4 Rc4 32.Rd1 -+ (-1.99) Depth: 11 00:11:24 209557kN 26.Bf4 Bxb2+ 27.Rxb2 Nc4 28.Bc1 Nxb2 29.Bxb2 Qa5 30.Kb1 e5 31.Nf3 a3 32.Rxd8+ Qxd8 33.Bc1 Rxc3 34.Nxe5 -+ (-1.98) Depth: 11 00:11:58 220132kN 26.Bf4 Bxb2+ 27.Rxb2 Nc4 28.Bc1 Nxb2 29.Bxb2 Qc5 30.Kb1 e5 31.Nf5 a3 32.Rxd8+ Rxd8 33.Bc1 -+ (-1.92) Depth: 11 00:12:58 238548kN 26.Bf4 Bxb2+ 27.Rxb2 Nc4 28.Rd3 Nxb2 29.Qxb2 Qb7 30.Re3 Rxd4 31.cxd4 Rc2 32.Qb1 Ra2+ 33.Qxa2 bxa2 -+ (-2.21) Depth: 12 00:23:58 453339kN 26.Nf3 Bxb2+ 27.Kxb2 Rxd2+ 28.Nxd2 a3+ 29.Kb1 Qa5 30.Bd4 Rxc3 31.Bxc3 Qxc3 32.Nxb3 Qxb3+ 33.Ka1 Qxh3 34.Ka2 Kh7 -+ (-2.06) Depth: 12 00:37:19 704195kN 26.Nf3 Bxb2+ 27.Kxb2 Rxd2+ 28.Nxd2 a3+ 29.Kb1 Qa5 30.Bd4 Rxc3 31.Bxc3 Qxc3 32.Nxb3 Qxb3+ 33.Ka1 Qxh3 34.Ka2 Kh7 -+ (-2.06) Depth: 13 00:47:08 888117kN 26.Nf3 Bxb2+ 27.Kxb2 Rxd2+ 28.Nxd2 a3+ 29.Kb1 Qa5 30.Bd4 Rxc3 31.Bxc3 Qxc3 32.Nxb3 Qxb3+ 33.Ka1 Qxh3 34.Ka2 -+ (-2.02) Depth: 15 06:35:29 3252746kN Uri
