Maybe it would be interesting to post some analysis from your programs in this position? I am saying that because, using Pro Deo, I get some very high scores for Black when Black plays 1..Bg4 . With a tactical engine even +7.78. So I am wondering if that move is not winning either. I don't know about 1..Be4 Have not analyzed it myself, seems complicated, but the position has been discussed here on CCC too. Are the settings missing something? I believe that only the Rebel Q5T settings play 1..Bh3 At least they used to back in 2000 or so. Uri more or less refused to accept that "because no program plays 1..Bh3" :) He was right of course, tactical settings do not really count. Have not tried the Q5T settings here with Rebel's successor Pro Deo. Now I think Bh3 gets pruned, even with Vulcan Q settings, but Q5T is simpler, has less switches and less pruning rules. No tactical settings: Pro Deo 1.1 Ripley: 00:00:00.5 2,08 10 391921 Bg4 Kh2 f5 Kg3 Kd6 Bb2 Kc5 Ba3+ Kc4 Bc1 00:00:00.5 2,11 10 494519 Bc2 Kg1 Kf5 Kf2 Ke4 Bb4 d4 Ke2 Bb3 Bc5 Bc4+ 00:00:00.6 2,14 10 569116 a3 Kg1 Bd3 Kf2 f5 Ke3 Bb1 g3 Be4 Kd2 00:00:00.7 2,18 10 667530 Be4 Bb2 f5 Kg1 Kd6 Kf2 Kc5 Ba3+ Kc4 Bc1 00:00:00.8 2,22 11 930168 Be4 Kg1 f5 Bb2 Kd6 Kf2 Kc5 g3 d4 Ke2 Kc4 Kd2 00:00:01.1 2,28 11 1228761 Kd6 Bd4 Bc2 g4 Bd1 Bxf6 Bxg4 Kg2 Kc5 Kg3 Bf5 Be7+ 00:00:01.2 2,28 11 1368541 Bc2 Kg1 Kf5 Kf2 Ke4 Bxf6 a3 Ba1 d4 Ke2 Bb3 00:00:01.7 2,29 12 2068624 Bc2 Kg1 Kf5 Kf2 Ke4 Bb2 Kd3 Bxf6 d4 h5 gxh5 Be7 00:00:02.9 2,34 13 3947605 Bc2 Kg1 Kf5 Kf2 Ke4 Bb2 Kd3 g4 Bd1 Bxf6 d4 h5 gxh5 gxh5 Bxh5 Be7 00:00:06.5 2,37 14 9151497 Bc2 Kg1 Kf5 Kf2 Ke4 Bb2 Kd3 g4 Bd1 Kg3 d4 Kf4 Bb3 h5 Bf7 hxg6 00:00:09.4 2,37 14 13525070 Bg4 00:00:10.5 2,62 14 15089527 Bg4 Kg1 Kf5 Bb2 Ke4 Bc1 d4 Bd2 Kd3 Bb4 f5 00:00:14.4 2,65 15 21407508 Bg4 Kg1 Kf5 Bb2 Ke4 Kf2 f5 00:00:27.3 2,81 16 43249265 Bg4 Kg1 Kf5 Bb2 Ke4 Kf2 f5 00:00:56.8 3,10 17 93482590 Bg4 Kg1 Kf5 Bb2 Ke4 Kf2 f5 00:02:23.4 3,18 18 242913668 Bg4 Bb2 Kf5 Kh2 Ke4 Kg3 f5 Kf2 Kd3 00:05:40.6 3,20 19 581631336 Bg4 Bb2 Kf5 Kg1 Ke4 Kf2 f5 Kg3 Ke3 00:17:03.7 3,21 20 1810354177 Bg4 Bb2 Kf5 Kh2 Ke4 00:43:23.2 3,38 21 383337281 Bg4 Bb2 Kf5 Kh2 Ke4 Kg3 f5 Tactical settings: Pro Deo 1.1 Vulcan Q1e 00:00:00.2 4,00 8 35861 Be4 Bb2 Bxg2+ Kxg2 f5 Kf3 a3 Bd4 Kd6 00:00:00.2 4,17 8 60142 Kd6 Bxf6 Kc5 Bb2 Be4 Ba3+ Kc4 Bc1 00:00:00.2 4,35 9 103800 Kd6 Bd4 Be4 Kg1 f5 h5 gxh5 Bb2 00:00:00.3 4,12 10 234093 Kd6 Bd4 Be4 Bxf6 Kc5 Bb2 d4 Ba3+ Kc4 Bc1 00:00:00.6 4,30 11 596796 Kd6 Bd4 Kc6 Kg1 Kb5 Kf2 Kc4 Ke3 Be4 Bxf6 Bxg2 00:00:00.8 4,37 11 953572 Bg4 Kh2 Kf5 Kg3 Ke4 Bb2 d4 Bc1 a3 Bxa3 Be6 00:00:01.1 4,75 12 1298349 Bg4 Kg1 Kf5 Bb2 Ke4 Kf2 d4 Bc1 Kd3 Bb2 Ke4 Bc1 Kd3 Bb2 00:00:01.8 4,96 13 2409867 Bg4 Kg1 Kf5 Bb2 Ke4 Kf2 d4 g3 Kd3 Kf1 f5 Ke1 Bf3 00:00:03.5 4,89 14 5003172 Bg4 Kg1 Kf5 Bb2 Ke4 Kf2 Kd3 g3 d4 Ke1 Bh5 Kf1 g5 Kf2 gxh4 00:00:08.6 4,80 15 13880422 Bg4 Kg1 Kf5 Bb2 Ke4 Kf2 d4 Bc1 Bh3 g3 Kd3 Bb2 Bg4 Kg2 Ke3 Ba3 Ke4 Bb4 Kd3 Bd6 f5 Kh2 00:00:12.8 4,80 15 20763584 a3 00:00:15.3 5,60 15 25043264 a3 Kg1 Bh3 Kf2 Kf5 g3 Ke4 Ke2 d4 Ba1 Be6 00:00:25.2 5,64 16 42240078 a3 Kg1 Bh3 Kf2 Kf5 g3 Ke4 Ke2 d4 Ba1 Be6 00:00:35.5 5,64 17 61979896 a3 Kg1 Bh3 Kf2 Kf5 g3 Ke4 Ke2 d4 Ba1 Be6 00:01:23.6 6,01 18 152755207 a3 Kg1 Bh3 Kf2 Kf5 g3 Ke4 Ke2 d4 Ba1 f5 Kd2 Kf3 Bxd4 Kxg3 Kc3 f4 Kb3 f3 00:01:33.5 6,01 18 168197678 Bg4 00:01:54.1 6,47 18 204724819 Bg4 Kg1 Kf5 Bb2 Ke4 Kf1 Bh5 Kf2 Kd3 Ke1 Kc2 Bxf6 a3 Be5 a2 00:06:09.7 7,35 19 673976446 Bg4 Bb2 Kf5 Kh2 Ke4 Kg3 f5 Ba3 Kd3 Kf2 00:14:13.3 7,78 20 1607551698 Bg4 Bb2 Kf5 Kh2 Ke4 Bxf6 a3 Ba1 Ke3 g3 I'm betting on Bg4!
