How long did you run it for?
Mine was 356 seconds on an i7 quad core. |

 | | agb2002: Black has the bishop pair for a bishop and a knight. The white queen lacks mobility. Black can take advantage of this to force a weakening of the white castle with 17... Rf3 18.gxf3 (18.Nd5 Rxd3 19.Nxe7 Rxd1 20.Rxd1 Bxe7 wins a piece) 18... Bf4: A) 19.Nxd4 Qg5+ 20.Kh1 Qh5 and mate in three.
B) 19.Rfe1 Qg5+ 20.Kh1 (20.Kf1 Bh3#) 20... Qh4 21.Kg1 Qxh2+ 22.Kf1 Qh1# (or 22... Bh3#). C) 19.Nd5 Bxh2+ 20.Kxh2 (20.Kh1 Qh4 and 20.Kg2 Qg4+ 21.Kg1 Qh4 and mate soon) 20... Qh4+ 21.Kg1 (21.Kg2 Bh3+ wins) 21... Bh3 22.f4 (22.Kh1(2) Bg4+ 23.Kg1 -23.Kg2 Qh3+ 24.Kg1 Bxf3 wins- 23... Bxf3 24.Qxf3 Nxf3+ and mate in two) 22... Qg4+ 23.Qg3 (else 23... Qg2#) 23... Ne2+ recovers material and should be winning for Black. D) 19.Ne2 Nxe2+ 20.Qxe2 Qh4 and mate in three. |

 | | Teyss: <nalinw: This was a Thursday (!!) puzzle in 2007> Depressing, isn't it? :-( On the other hand the opposite sometimes happens, with mid-week of even Monday puzzles that are more difficult than standard. Brilliant combination although Black missed a quicker win: 25...Qh5 instead of 25...Bxf1. See Dilbertarian's and subsequent kibitzes on the first page for more detail. The computer evals are close but in human mode it's easier to win a net R than R for B. Oh and of course I didn't get it. Saw 17...Rf3 and 18...Bf4 but chickened out on 19...Bxh2+. |

Aug-15-21 | | Brenin: <rwbean>: I think 17 Nd5, instead 17 Qd3, gives White the advantage, e.g. 17 ... Bxd2 18 Nxe7 Bg5 19 Nxc8 R(either)xc8 20 Nxd6, winning a P; it doesn't help Black to interpose Nxb5 cxb5 since this allows an eventual Rxd6. If the Q retreats, e.g. 17 ... Qd8, then 18 f4 looks strong. |
