Comments by DuWayne Langseth: Anthea and David always seem to have interesting games. Anthea because she has taken up the philosophy of Master Wall to attack the king number one and all else second. David plays more like I do looking for the best move in all positions no matter where that leads. In this one where they are matched, Anthea's well-executed attack gains her a quick exchange advantage, but David has a bishop pair for compensation. Then he begins to find correct moves and hers are harder to find. Finally, his more accurate endgame play brings him the victory.
1.d4 Nf6 2.Nf3 b6 3.Bf4 e6 4.e3 Bb7 5.Be2 Be7 6.h3 d5 7.Nbd2 Nbd7 8.Bh2 c5 9.c3 0-0 10.0-0 Ne8 11.Ne5 f6 12.Nxd7 Qxd7 13.f4 Nd6 14.g4 One obvious sign that you've been influenced by Brian Wall is that you play g4 often as a fundamental part of your attack on the enemy king. Whenever I watch Tyler Hughes games, I anticipate this move.
14...Nf7 15.Nf3 Bd6 16.Bd3 Rae8 17.Qc2 The black king is beginning to feel the pressure now.
17...h6 [David likely was not comfortable with the way things looked after 17...g6 18.Bxg6 hxg6 19.Qxg6+ Kh8 20.Qxf6+ Kh7 Rybka gives Black the edge, but near-perfect play would be required as the dark king is in peril.]
18.Nh4 ! It's going to be tough for Black to keep from dropping material now with the white knight in his face.
18...Nh8 19.Bh7+ ! Winning the exchange, but Black will have the bishop pair.
19...Kf7 20.Ng6 Anthea has played a series of best moves here, though Rybka is torn between her path of taking the rook for bishop and a slower attack bringing the queens rook to e1.
20...Nxg6 21.Bxg6+ Ke7 22.Bxe8 Qxe8 Rybka preferred taking with the rook because now f5! keeps the black queen out of the kingside. Black's dark bishop would have come off too. The computer scores it +1.1 here.
23...f5 ! Black gets to keep his dark squared bishop a while longer and has hope of bringing his own attack on the enemy king.
24.Qg2 Rg8 25.a5 Likely one of two best moves here.
25...b5 Black correctly disallows the exchange on b6, which would have made things much easier for White with the eventual Ra7.
26.g5 It's tough to find a good continuation here. White's advantage is down to half a pawn.
26...Qh5 27.Qf3 Slightly better may have been [27.gxh6 Qxh6 28.Qg5+ ]
27...Qh4 28.Qg3 Qxg3+ For some strange reason that is unclear to me, Rybka favors not winning the pawn, but rather keeping the queens on the board with [28...Qh5 29.gxh6 Kf7 30.Qf3 Qxh6 I think I prefer David's choice.]
29.Bxg3 hxg5 30.Kf2 gxf4 31.Bxf4 g5 ? Now, Rg1! would be give White a clear advantage.
32.Bxd6+ Kxd6 33.dxc5+ ? This just makes a path for the black king, but again it's hard to find the best continuation. What White really needs is an open file, so 33. h4 may have been the way to go.
33...Kxc5 34.Rad1 e5 35.Ke1 Bc8 36.Rf2 Be6 37.Rh2 Rh8 38.Rdd2 Kc4 It's pretty even here.
39.Kd1 Kb3 40.Kc1 Ka4 41.b4 Kb3 42.Rb2+ White has done an ok job of defending lately, but Rdg2 was probably best here. Now Black can just take on c3, though he doesn't.
42...Kc4 43.Rbg2 ! Likely best for White.
43...Rg8 ? Now Kd2 would have made things much easier for White. Once again, the c-pawn is hanging, but Black is afraid to take it.
44.Re2 Rh8 45.Kb2 Kd3 46.Reg2 Rh5 47.Rg3
Rd2+ was better offering the e-pawn in exchange for a perpetual check. Now Black's kingside pawns advance with the White king far from the action.
47...g4 48.h4 Ke4 49.Kc2 f4 50.exf4 exf4 51.Re2+ ! White finds one last possible saving grace.
51...Kf5 52.Rxe6 ? [52.Rxg4 ! 52...Kxg4 53.Rxe6 would have made it interesting.]
52...fxg3 Game over.
53.Re1 Kf4 54.Rf1+ Ke3 55.Re1+ Kf2 56.Rd1 g2 0-1
