That is if we don't run into a false fail-high. A little over an hour, Athlon 3200+ with 200 Mb HT. So far only with a "better than draw" evaluation because of the fail-high. Well at least that shows the move 28.Ra7! can be found by the computers, and there will be faster programs out there I am sure. Maybe Pro Deo default is faster. 1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Be3 Bg7 5.Qd2 c6 6.f3 b5 7.Nge2 Nbd7 8.Bh6 Bxh6 9.Qxh6 Bb7 10.a3 e5 11.O-O-O Qe7 12.Kb1 a6 13.Nc1 O-O-O 14.Nb3 exd4 15.Rxd4 c5 16.Rd1 Nb6 17.g3 Kb8 18.Na5 Ba8 19.Bh3 d5 20.Qf4 Ka7 21.Rhe1 d4 22.Nd5 Nbxd5 23.exd5 Qd6 24.Rxd4 cxd4 25.Re7 Kb6 26.Qxd4 Kxa5 27.b4 Ka4 [D]b2r3r/4Rp1p/p2q1np1/1p1P4/kP1Q4/P4PPB/2P4P/1K6 w - - 00:00:00 1.00 -8.26 28.Be6 Qxe7 00:00:00 1.01 -3.36 28.Rxf7 Nxd5 00:00:00 1.12 -3.36 28.Qe3 Bxd5 00:00:00 2.00 -3.32 28.Qe3 Bxd5 00:00:00 3.00 -4.48 28.Qe3 Qxd5 29.Qc1 Qxf3 00:00:00 3.04 -3.57 28.Qc3 Qxd5 29.Re1 Qxf3 00:00:00 3.14 -3.48 28.Re3 Bxd5 29.Kc1 00:00:00 3.21 -3.31 28.Qd3 Bxd5 29.Qe3 00:00:00 4.00 -5.77 28.Qd3 Qxd5 29.Qe3 Qd1 30.Kb2 00:00:00 4.01 -3.92 28.Re3 Bxd5 29.Qb2 Be6 00:00:00 4.03 -3.72 28.Qc3 Bxd5 29.Re5 Ra8 00:00:00 5.00 -4.09 28.Qc3 Bxd5 29.Re3 Rhe8 30.Rd3 00:00:00 6.00 -4.41 28.Qc3 Bxd5 29.Re3 Rhe8 30.Rd3 Re2 00:00:00 6.04 -4.39 28.Qe3 Qxd5 29.Ra7 Rd6 30.Kb2 00:00:00 7.00 -4.39 28.Qe3 Qxd5 29.Ra7 Rd6 30.Kb2 00:00:00 7.01 -4.39 28.Qc3 00:00:00 7.01 -3.48 28.Qc3 Qxd5 29.Qxf6 Qd1 30.Kb2 a5 31.Qxf7 00:00:00 8.00 -2.64 28.Qc3 Qxd5 29.Ra7 Bb7 30.Rxb7 Qc4 31.Qe1 Rhe8 00:00:00 8.01 -2.64 28.Qe3 00:00:00 8.01 -2.26 28.Qe3 Qxd5 29.Ra7 Bb7 30.Rxb7 Rhe8 31.Qc3 Qd1 32.Ka2 00:00:01 9.00 -2.45 28.Qe3 Qxd5 29.Ra7 Bb7 30.Rxb7 Rhe8 31.Qc3 Re2 32.Kb2 00:00:01 9.01 -2.45 28.Qc3 00:00:01 9.01 -2.45 28.Qc3 00:00:02 9.01 0.00 28.Qc3 Qxd5 29.Qc7 Qd1 30.Kb2 Qd4 31.Kb1 Qd1 32.Kb2 Qd4 33.Kb1 00:00:02 10.00 0.00 28.Qc3 Qxd5 29.Qc7 Qd1 30.Kb2 Qd4 31.Kb1 Qd1 32.Kb2 Qd4 33.Kb1 00:00:04 11.00 0.00 28.Qc3 Qxd5 29.Qc7 Qd1 30.Kb2 Qd4 31.Kb1 Qd1 32.Kb2 Qd4 33.Kb1 00:00:07 12.00 0.00 28.Qc3 Qxd5 29.Qc7 Qd1 30.Kb2 Qd4 31.Kb1 Qd1 32.Kb2 Qd4 33.Kb1 00:00:19 13.00 0.00 28.Qc3 Qxd5 29.Qc7 Qd1 30.Kb2 Qd4 31.Kb1 Qd1 32.Kb2 Qd4 33.Kb1 00:00:47 14.00 0.00 28.Qc3 Qxd5 29.Qc7 Qd1 30.Kb2 Qd4 31.Kb1 Qd1 32.Kb2 Qd4 33.Kb1 00:02:36 15.00 0.00 28.Qc3 Qxd5 29.Qc7 Qd1 30.Kb2 Qd4 31.Kb1 Qd1 32.Kb2 Qd4 33.Kb1 00:07:08 16.00 0.00 28.Qc3 Qxd5 29.Qc7 Qd1 30.Kb2 Qd4 31.Kb1 Qd1 32.Kb2 Qd4 33.Kb1 00:17:29 17.00 0.00 28.Qc3 Qxd5 29.Qc7 Qd1 30.Kb2 Qd4 31.Kb1 Qd1 32.Kb2 Qd4 33.Kb1 00:33:19 18.00 0.00 28.Qc3 Qxd5 29.Qc7 Qd1 30.Kb2 Qd4 31.Kb1 Qd1 32.Kb2 Qd4 33.Kb1 01:12:20 18.05 0.00 28.Ra7 Newly hatched Pro Deo 1.1 Vulcan {9k16hv} testversion is same as {9k16h5} but [Right to Move = 85], from 80.
