Kibitzer's Corner
Jan-11-08  piroflip: If this Queen sac had been done by Gary it would have made the headlines.
Jan-11-08  Gilmoy: White played 12.Nxe5 to win a pawn -- thinking that 13.f4 recovers his piece "with advantage". He overlooked that Black had the choice of giving his Q+P + counterplay for R+N. Since Black accepted that line, he must have seen at least 3 pawns' worth of counterplay.

Once we get past the mental block of the N being "pinned", we see that White's position is awful. At 15, Black already has three threats: Re1+, Rad8, and Ng4-Bd4+. White has weak back rank (corollary: he has two pieces out of play, B+R -- so he's the one who's down in material!), and his only active piece is a Q, who gets kicked around by a 5-on-1 firestorm.

After the Q sac, 6 of 8 White moves were by its Q or its K, as Black saunters to a mating net.

a) B+ along the a8-f3 diagonal, e.g. Be4, or 22.c5+ Be6 23.Q<runs> Bd5#.

If the Q leaves 3, e.g. 22.Qxb7 (to control e4, haha):

b1) Rd3+ 23.Be3 Rdxe3#

b2) Nxh2+ 23.Kf2 Bd4+ and mate next if the Q doesn't control e3, or wins even if she does: 24.Be3 Bxe3+ 25.Qxe3 Ng4+ etc.

Jan-11-08  whiteshark: Shortly afterwards white blundered with <15.Ne4??> Instead <15.Bd2> looks like the only playable continuation with <15...Rad8 16.c5>
Jan-11-08  whiteshark: But with the addition that black could play perfectly <13...Bg4!> to secure the material advantage, e.g. <14.Qd2 Rd8> and now either <15.Qf2 Nh5> or <15. Nd5 Nxc4>
