You're right about 26.e5, that was a blunder. Up till then, white has it won, though the position is dangerous. I think Amateur played this game very well, except for that one move. I tried analyzing it, once using the epd, once playing thru the game using my pgn reader, and once setting it up manually (and manually setting white castled). I got three different analyses, indicating I'm doing something wrong in figuring castle privileges, which affects king-safety. The move 26.e5 is played only when using the pgn readed, which should mimic game conditionns. So, obviously something is wrong. epd... ply score time nodes pv 5 90 0.52 37437 a5 Qb4 Ka1 Qxa5 Qd2 Qa3 5 103 1.07 51436 Rb1 Qxa4 Rd1 c4 Ka1 5 104 1.21 65369 e5 Nd5 Qe1 Pxe5 f4 6 76 2.11 104803 e5 Nd5 Qe1 Pxe5 Rd2 Rf5 6 91 4.21 211038 a5 Nc6 Rd2 Nxa5 Rb1 e5 6 96 5.39 281523 f4 Qxa4 Qb3 Qb4 Qxb4 Pxb4 Kb3 7 95 7.17 364741 f4 Qxa4 Qb3 Qb4 a3 Qxb3 Kxb3 Kd7 7 101 11.43 614214 Ka1 Nc6 Qb3 Qxb3 Pxb3 Nd4 f4 Nxb3 Kb2 8 67 15.42 842555 Ka1 Nc6 Qb3 Qxb3 Pxb3 Nd4 Rd3 Rxf2 Rd1 8 82 21.48 1193904 Rd2 Nc6 Kb1 Qxa4 Rb2 Qd4 Qe2 c4 8 93 24.53 1372224 f4 Qxa4 Qb3 Qxe4 Qb8 Kf7 Qxc7 Qg2 Ka1 d5 Qxc5 Qxg3 pgn (game condition)... ply score time nodes pv 5 168 1.22 51629 e5 Nf5 Qe1 Nd4 Pxd6 Pxd6 5 177 1.38 64483 Ka1 Qxa4 f4 Rf6 Rb1 5 181 1.56 82354 Rd2 Qb4 Ka1 Qxa4 Rb1 c4 5 192 2.25 102611 Rb1 Qxa4 Rd1 Rf6 Qe2 6 177 3.09 132678 Rb1 Qxa4 Rd1 Rf6 g4 c4 6 185 6.31 319022 e5 Qb4 Ka1 Nd5 Qe1 Qxe1 Rxe1 Rxf2 Pxd6 Pxd6 7 111 12.39 668009 e5 Nd5 Qd2 Qxa4 Rh4 Qb5 Ka1 Pxe5 7 163 16.28 872609 h6 Qb4 Ka1 Qxa4 Rd2 Kd8 Rb1 Kc8 7 168 20.15 1081306 a5 Nc6 f4 Qb5 Ka1 Kd7 Rb1 Qxa5 7 177 22.42 1225653 Rb1 Qxa4 Rd1 Kd7 Ka1 Kc8 Rb3 8 138 30.43 1675875 Rb1 Qxa4 Ka1 Kd7 Rb2 Nc6 Rc1 Nd4 8 162 41.59 2320322 Rd2 Nc6 Kb1 Qxa4 Rb2 Qd4 Qe2 c4 manual... ply score time nodes pv 5 81 0.48 34618 a5 Qb4 Ka1 Qxa5 Rb1 Rf6 5 83 1.09 51664 e5 Nd5 Qe1 Pxe5 Ka3 5 86 1.32 73983 Rd2 Qb4 Ka1 Qxa4 Rb1 c4 5 88 1.51 89268 Rb1 Qxa4 Rd1 c4 Ka1 6 69 2.28 124218 Rb1 Qxa4 Rc1 c4 Ka1 d5 6 79 4.56 245530 a5 Nc6 Rc1 Nxa5 Rd1 Qb4 Ka1 7 73 8.56 467376 a5 Nc6 f4 Qb4 Ka1 7 86 10.25 554203 Rb1 Qxa4 Rd1 c4 Ka1 Nc6 Qe2 8 78 15.55 876609 Rb1 Qxa4 Ka1 Nc6 Rb7 Nd4 Rb8 Ke7 Rb1 8 81 26.08 1466308 a5 Nc6 Rd2 Qb4 Ka1 Qxa5 Rb1 Nd4 Rb7
