Hello everybody, I am having some difficulty interpreting this position. Is 12.Nxe5 the only move? Is White winning regardless? Should I throw away my latest settings for Pro Deo? [D]rnbq1rk1/pp1n1p1p/4p1p1/3pP1NP/1b3P2/1PpB4/P1P3P1/R1BQK2R b KQ - 0 1 I had some slightly conflicting search results in the position I gave in my last post http://www.talkchess.com/forums/1/message.html?418597. That only makes it a more interesting position I think. Pro Deo 1.1 Betazoid T6c met [Queen Value = 95] 01:11:50.6 0,00 13 566269012 Nxe5 fxe5 Qc7 Qe2 01:30:45.5 0,01 13 721163232 Nc6 hxg6 fxg6 Nxh7 Qe8 Rh6 Pro Deo 1.1 Betazoid T6e2 02:29:01.0 0,28 13 1232946950 Nc6 Nxh7 g5 h6 Kh8 Nxf8 Qxf8 05:42:39.8 0,39 14 -1368052790 Nc6 Nxh7 g5 Qg4 S&D 6_7e3 Pro Deo 1.1 surprisingly to the point. I expected many switches not to be working anymore. But overall this search seems good, in this postion at least. 00:00:00.5 1,88 1 26 gxh5 Bxh7+ Kh8 Qxh5 00:00:00.5 3,72 1 28 Nc6 00:00:00.5 3,80 1 48 Qb6 00:00:00.5 2,82 2 163 Qb6 hxg6 hxg6 00:00:00.5 2,90 2 242 Bc5 hxg6 hxg6 00:00:00.6 3,23 2 820 h6 a3 00:00:00.6 3,44 3 1627 h6 Nf3 gxh5 Rxh5 00:00:00.6 3,27 4 6174 h6 Nxf7 Kxf7 Qg4 Nxe5 hxg6+ 00:00:00.8 2,85 5 17265 h6 hxg6 hxg5 g7 Kxg7 a3 00:00:00.8 3,26 5 28615 Be7 hxg6 hxg6 Nf3 Nc5 Bb5 00:00:01.1 3,31 6 61197 Be7 hxg6 hxg6 Nf3 Nc5 Qe2 Bd7 00:00:06.4 2,05 7 729200 Be7 Nxh7 Bh4+ Kf1 Kxh7 hxg6+ Kg7 Qh5 00:00:14.8 2,34 8 1808764 Be7 Nxh7 Bh4+ Kf1 Kxh7 hxg6+ Kg7 gxf7 Nxe5 Qh5 Nxd3 00:00:18.8 1,57 9 2339553 Be7 Nxh7 Bh4+ Kf1 Kxh7 Qg4 Kg8 Rxh4 g5 00:00:57.6 0,98 10 7808043 Be7 Nxh7 Bh4+ Kf1 Kxh7 Qg4 Kg8 Rxh4 g5 Ba3 00:04:50.4 0,46 11 40080820 Be7 hxg6 fxg6 Bxg6 Bxg5 Bxh7+ Kg7 Qh5 Qe7 g3 Nc6 00:07:36.5 0,71 11 65032803 Nc6 Nxh7 Be7 Kf1 00:09:25.8 0,87 11 81944119 Nxe5 fxe5 Qc7 Qe2 f6 exf6 00:17:53.7 0,50 12 161369733 Nxe5 fxe5 Qc7 Qg4 00:21:28.3 0,58 12 194454123 Nc6 Nxh7 Bc5 Nxf8 Nxf8 hxg6 01:07:52.3 0,21 13 616796324 Nc6 hxg6 fxg6 Nxh7 Bc5 Bxg6 01:42:37.6 0,32 13 938572412 Bc5 hxg6 fxg6 Nxh7 Rf7 Ng5 04:17:13.5 0,06 14 -1940861402 Bc5 hxg6 hxg6 Qg4 Assuming this is anywhere near correct than 12.Nxe5, 12.Nc6 and 12.Bc5 all have chances to draw.

Also [Pruning = MISC_30] * extend singular checks idem. This is responsible for including Nxe5 in the search. Maybe this extension description is not valid anymore but it works. So I take back the "Grrr" from my last post about 12.Nc6! Just had to report this before every programmer starts tuning for a version of their own programs that plays 12.Nxe5 only!
