But after looking at it with chess programs(Yace, fruit and chess tiger) im not sure, although they give black a better score they all try all kinds of checks. So is this a draw or does someone have another conclusion ? But only Yace tries Kb3 after some thought, and this line looks like a draw to me. >1.5Ghz Centrino, 256Mb Hash no TB >00:00:00.0 -0,93 1 6 exf5 Bxf5 >00:00:00.0 -0,90 1 22 Qe7 >00:00:00.0 -0,90 1 38 Qe7 >00:00:00.0 -0,96 2 175 Qe7 Ba4 >00:00:00.0 -0,95 2 448 d6 Ba4 >00:00:00.1 -0,95 2 488 d6 Ba4 >00:00:00.1 -0,95 2 741 d6 Ba4 >00:00:00.1 -1,23 3 3021 d6 Qe1+ Kb3 Qd2 >00:00:00.1 -1,22 3 4245 Qe7 Qh1 >00:00:00.1 -1,03 3 5072 Qe7 Ba4 Qe6+ Kf8 >00:00:00.1 -1,03 3 5732 Qe7 Ba4 Qe6+ Kf8 >00:00:00.1 -1,63 4 6070 Qe7 Ba4 Qe6+ Kf8 exf5 Bxc2 >00:00:00.1 -2,09 4 9710 Qe7 Ba4 Qe6+ Kf8 exf5 Bxc2 Qxg6 >00:00:00.1 -2,08 4 13623 d6 Nxd6 Qxd6 fxe4 >00:00:00.1 -2,17 4 14237 d6 Ba4 Qd5+ Kf8 exf5 Bxc2 >00:00:00.1 -2,09 4 14237 Qe7 Ba4 Qe6+ Kf8 exf5 Bxc2 Qxg6 >00:00:00.2 -2,08 4 18419 h4 Qe1+ Kb2 Ba4 >00:00:00.2 -2,03 4 19948 h4 Ba4 Qf2 Qa3+ Kd2 >00:00:00.2 -2,00 4 23677 Qb6 Qe1+ Kb3 Qd2 exf5 Qxd5 >00:00:00.2 -1,65 4 31452 Qb6 Qa1+ Kd2 Qf1 Qb7 >00:00:00.3 -1,64 4 38095 Qb4 Qe1+ Kb3 Qxb4+ Kxb4 Bb5 >00:00:00.3 -1,32 4 44355 Qb4 Qa1+ Kb3 Nf6 Qb8+ Kf7 exf5 gxf5 >00:00:00.3 -1,32 4 45916 Qb4 Qa1+ Kb3 Nf6 Qb8+ Kf7 exf5 gxf5 >00:00:00.3 -1,32 5 64505 Qb4 Qa1+ Kb3 f4 Qe7 Qa4+ Kb2 >00:00:00.4 -1,32 5 75274 Qb4 Qa1+ Kb3 f4 Qe7 Qa4+ Kb2 >00:00:00.6 -1,29 6 249089 Qb4 Qe3+ Kb2 Qe2 Qe7 Ba4 Qe6+ Kf8 >00:00:00.6 -1,29 6 281258 Qb4 Qe3+ Kb2 Qe2 Qe7 Ba4 Qe6+ Kf8 >00:00:00.8 -1,61 7 472560 Qb4 Qe3+ Kb2 Qe2 c5 Qxg2 c6 Bc8 >00:00:01.4 -1,60 7 945399 Kd3 Qf1+ Kc3 Qxg2 Qe7 Bc8 Qxe8+ Kg7 >00:00:01.9 -1,35 7 1350629 Kd3 Qf1+ Kc3 Qa1+ Kd2 f4 g3 Qh1 Qf2 Nd6 >00:00:01.9 -1,35 7 1356425 Kd3 Qf1+ Kc3 Qa1+ Kd2 f4 g3 Qh1 Qf2 Nd6 >00:00:04.0 -1,68 8 3172465 Kd3 Nf6 Qe7 fxe4+ fxe4 Qf1+ Kc3 Qa1+ Kd2 Qxa5+ Kd3 >Nxe4 Kxe4 Bf5+ Kxe5 Bxc2 >00:00:04.5 -1,67 8 3575137 Qb4 Qe3+ Kb2 Qe2 c5 Qxg2 c6 Ng7 >00:00:04.7 -1,48 8 3818228 Qb4 Qe3+ Kb2 Qe2 c5 Qxg2 c6 Bc8 Qe7 >00:00:05.1 -1,48 8 4103054 Qb4 Qe3+ Kb2 Qe2 c5 Qxg2 c6 Bc8 Qe7 >00:00:11.5 -1,23 9 9562144 Qb4 f4 Kb3 Qe3+ Qc3 Ba4+ Kb4 Bxc2 Qxc2 Nd6 Qc3 Qe2 >00:00:12.3 -1,23 9 10172961 Qb4 f4 Kb3 Qe3+ Qc3 Ba4+ Kb4 Bxc2 Qxc2 Nd6 Qc3 Qe2 >00:00:21.1 -1,29 10 18383992 Qb4 Kf7 Qb7 Nf6 exf5 gxf5 Qc7 Qe1+ Kb3 Qe3+ Kb2 Qe2 >g3 Ke7 >00:00:25.0 -1,29 10 21659853 Qb4 Kf7 Qb7 Nf6 exf5 gxf5 Qc7 Qe1+ Kb3 Qe3+ Kb2 Qe2 >g3 Ke7 >00:00:37.5 -1,69 11 31424231 Qb4 fxe4 fxe4 Nf6 c5 Bg4 Kb3 Bd1 Qb8+ Kg7 Qxe5 >Bxc2+ Kb4 >00:00:41.7 -1,72 11 35226420 Qb4 fxe4 fxe4 Nf6 c5 Bg4 Kd3 Be2+ Kxe2 Qxc2+ Ke1 >Qc1+ Ke2 Qf4 Qb8+ Kg7 d6 >00:01:14.3 -1,71 11 61252052 Kb3 Ba4+ Kxa4 Qxc2+ Kb4 Qxg2 Qc6 Qd2+ Ka4 Kf8 exf5 >gxf5 Qc5+ Kf7 Qa7+ Nc7 Qxc7+ Kf6 >00:01:32.5 -0,89 11 77161225 Kb3 Ba4+ Kxa4 Qxc2+ Kb4 Qxg2 Qe7 Qb2+ Ka4 Ng7 Qd8+ >Kf7 Qc7+ Kf8 Qc8+ Ke7 d6+ Kxd6 Qf8+ Kc7 Qxg7+ Kc8 >00:01:32.8 -0,89 11 77385569 Kb3 Ba4+ Kxa4 Qxc2+ Kb4 Qxg2 Qe7 Qb2+ Ka4 Qc2+ Kb4 >Qd2+ Ka4 Qd1+ Kb4 Qe1+ Ka4 Qa1+ Kb4 Ng7 Qd8+ Kf7 Qd7+ Kf8 Qd6+ Ke8 >00:01:33.0 -0,89 11 77555422 Kb3 Ba4+ Kxa4 Qxc2+ Kb4 Qxg2 Qe7 Qb2+ Ka4 Qc2+ Kb4 >Qd2+ Ka4 Qd1+ Kb4 Qe1+ Ka4 Qa1+ Kb4 Ng7 Qd8+ Kf7 Qd7+ Kf8 Qd6+ Ke8 >00:01:59.0 -0,89 12 100687017 Kb3 Ba4+ Kxa4 Qxc2+ Kb4 Qxg2 Qe7 Qb2+ Ka4 Qc2+ Kb4 >Qd2+ Ka4 Qd1+ Kb4 Qe1+ Ka4 Qa1+ Kb4 Ng7 Qd8+ Kf7 Qd7+ Kf8 Qd6+ Ke8 Qb8+ Ke7 >00:02:08.1 -0,89 12 107691845 Kb3 Ba4+ Kxa4 Qxc2+ Kb4 Qxg2 Qe7 Qb2+ Ka4 Qc2+ Kb4 >Qd2+ Ka4 Qd1+ Kb4 Qe1+ Ka4 Qa1+ Kb4 Ng7 Qd8+ Kf7 Qd7+ Kf8 Qd6+ Ke8 Qb8+ Ke7 >00:06:23.4 -0,78 13 314347353 Kb3 Ng7 Qe7 Qe3+ Kb4 Qd2+ Kb3 Be8 exf5 Ba4+ Kxa4 >Qxc2+ Kb4 Qb2+ Ka4 Qa1+ Qa3 Qb1 >00:06:44.9 -0,78 13 329882043 Kb3 Ng7 Qe7 Qe3+ Kb4 Qd2+ Kb3 Be8 exf5 Ba4+ Kxa4 >Qxc2+ Kb4 Qb2+ Ka4 Qa1+ Qa3 Qb1 >00:07:29.6 -0,78 13 364694767 Kb3 Ng7 Qe7 Qe3+ Kb4 Qd2+ Kb3 Be8 exf5 Ba4+ Kxa4 >Qxc2+ Kb4 Qb2+ Ka4 Qa1+ Qa3 Qb1
