Just because getting 9 ply takes time. Fail high takes 52 seconds, resolving it some more time. To some extend this is a positional determined position for computer. I bet most programs see the fundamental tactics pretty soon as it's all with check. Only at bigger depths of course big scores come there. But getting the first time Bb5 seems pretty king safety determined. 00:00 0 0 3 (0) 1 0.069 Be8xa4 00:00 0 0 170 (0) 2 -0.022 Be8xa4 Ne4-c5 00:00 0 0 1548 (521) 3 -0.059 Be8xa4 Nb3-d4 Nh5-g3 Ne4xg3 Nf5xg3 h2xg3 h4xg3 Kh1 -g1 00:00 0 0 5393 (930) 4 -0.059 Be8xa4 Nb3-d4 Nh5-g3 Ne4xg3 Nf5xg3 h2xg3 h4xg3 Kh1 -g1 00:00 0 0 33437 (7733) 5 0.106 Be8xa4 Qe2-f3 g7-g6 Nb3-c5 Ba4-b5 00:01 0 0 92187 (17723) 6 -0.019 Be8xa4 Nb3-d4 Ba4xc2 Rc1xc2 g7-g6 b4-b5 00:05 0 0 487863 (68488) 7 0.043 Be8xa4 Nb3-d4 Nh5-g3 Ne4xg3 h4xg3 Rf1xf5 Rh8xh2 Kh1-g1 Rg8-h8 00:11 0 0 1140797 (176338) 8 -0.015 Be8xa4 Nb3-d4 Nf5xd4 c3xd4 Ba4xc2 Rc1xc2 Qc8 -d7 Qe2-c4 f7-f6 00:44 0 0 4469422 (932026) 9 -0.001 Be8xa4 Nb3-d4 Ba4xc2 Rc1xc2 Nf5-d6 Ne4-c5 Qc 8-c7 Nc5xa6 b7xa6 Qe2xa6 Qc7-a7 ++ e8-b5 01:32 0 0 9274629 (2250196) 9 0.084 Be8-b5 Qe2-f3 Bb5xf1 Rc1xf1 Nf5-d6 Ne4xd6 Bf 8xd6 Bc2-d3 Nh5-f4 Bd3xa6 02:46 0 0 16698796 (6079007) 10 0.603 Be8-b5 a4xb5 Nh5-g3 Ne4xg3 Nf5xg3 h2xg3 h4 xg3 Kh1-g1 Rh8-h1 Kg1xh1 Rg8-h8 Kh1-g1 Bf8-c5 Rf1-f2 g3xf2 Qe2xf2 Bc5xf2 Kg1xf2 a6xb5 05:43 0 0 34938707 (7140150) 11 2.976 Be8-b5 Qe2-f3 Nh5-g3 Ne4xg3 Nf5xg3 Kh1-g1 Bb5xf1 h2xg3 Bf1-c4 Bc2-f5 Bc4-e6 Nb3-d4 h4xg3 Bf5xe6 f7xe6 Qf3xg3 >rn1qr1k1/pbp2pb1/1p4p1/3p4/3P4/2NBPN2/PPQ2PP1/R3K2R w KQ - bm Bxg6; id >"WCSAC.0965"; > >Solved after 3:12 0:01 here.
