Lukey's upset victory over Chandler from the 115th Congress

The following game illustrates the importance of opening knowledge and that sometimes winning the opening phase of the game is not always a guarantee of victory.

Lukey,S - Chandler,M [D43]New Zealand Championship Auckland (2.1), 16.01.2008

1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3 c6 5.Bg5 This is probably the most popular opening for both colours at the GM level world wide!
5...h6 The Anti moscow variation
6.Bh4 dxc4 7.e4 g5 8.Bg3 b5 9.Be2 Bb7 10.h4
A recent game went 10.0-0 Nbd7 11.Ne5 Bg7 12.Nxf7! Topalov and his teams new novelty at the recent Corus tournament. 12...Kxf7 13.e5 Nd5 14.Ne4 Ke7 15.Nd6 Qb6 16.Bg4 Raf8 17.Qc2 Qxd4 18.Qg6 Qxg4 19.Qxg7+ Kd8 20.Nxb7+ Kc8 21.a4 b4 22.Rac1 c3 23.bxc3 b3 24.c4 Rfg8 25.Nd6+ Kc7 26.Qf7 Rf8 27.cxd5 Rxf7 28.Rxc6+ Kb8 29.Nxf7 Re8 30.Nd6 Rh8 31.Rc4 Qe2 32.dxe6 Nb6 33.Rb4 Ka8 34.e7 Nd5 35.Rxb3 Nxe7 36.Rfb1 Nd5 37.h3 h5 38.Nf7 Rc8 39.e6 a6 40.Nxg5 h4 41.Bd6 Rg8 42.R3b2 Qd3 43.e7 Nf6 44.Be5 Nd7 45.Ne6 1-0 Topalov,V-Kramnik,V/Wijk aan Zee NED 2008

12...Nbd7 13.fxg4 hxg4 14.0-0 Nxe5 15.Bxe5

Rh6! This appears to be a strong novelty. A previous game goes 15...Nd7 16.Bxh8 Qxh4 17.Bxg4 Qxh8 18.e5 0-0-0 19.Qe2 c5 20.d5 Nxe5 21.dxe6 Nxg4 22.Qxg4 Qd4+ 23.Qxd4 cxd4 24.Nxb5 fxe6 25.Rac1 Bh6 26.Rxc4+ Kb8 27.Re1 Be3+ 28.Rxe3 dxe3 29.Rd4 Rf8 30.Rd1 a6 31.Nc3 Rf2 32.Rd6 e5 33.Re6 Rf5 34.Rg6 Rf2 35.Rg5 Rxb2 36.Rxe5 Rxg2+ ½-½ Bacrot,E-Dreev,A/Poikovsky RUS 2005
16.Qd2? Allowing a simple combination. The position however is incredibly complicated. Analysis with a computer aid gives black the advantage in most lines but this is by no means the final say as deep study is required to find the truth in the position. But generally black gives up the exchange for a strong attack or he gets to keep his pawn with no compensation for white. 16.Bxg4 Nxg4 17.Qxg4 Qxh4 18.Qg8 (18.Qxh4 Rxh4 19.Bf6 Rg4 20.Rae1 Black is a pawn up again with no compensation for white.) 18...Qh5 19.Bg7 0-0-0 20.Bxh6 Bxh6 21.Qg3 (21.Qxf7?? Be3+) 21...b4 22.Na4 Rxd4 lack has a strong attack;
16.Bf4 This leads to wild complications.;
16.g3 To protect the h-pawn, if this pawn were to drop off then white's king will be under heavy attack in conjunction with a black pawn moving to g3. 16...b4 17.Nb1!? (17.Bxf6 Rxf6 18.Na4 Rxf1+ 19.Bxf1 Ba6 20.e5 Bb5 21.Nc5 Bxc5 22.dxc5 Qd5 23.Qxg4 0-0-0 Black is better. White's c-pawn will fall off and white's king is left a little open.) 17...Nxe4 18.Bxc4 Qd7 19.Nd2 Nxd2 20.Qxd2 Again white has no compensation for the pawn deficit
16...b4 17.Na4 Nxe4 18.Qf4 f5 19.g3 Rg6 20.Qe3 Qd5 21.h5 Rg5 22.Rac1 Rxh5 23.Bxc4 Qd7 24.Bd3 Ng5 25.Kf2 Nf3 [25...Rh2+ 26.Ke1 Nf3+ 27.Kd1 Bh6-+]
26.Rh1 Rxh1 Lukey said this on chesschat forum."Murray's mistake was to swap rooks and give me the h file and then swap on e5 letting my queen get there - he had planned Bg7 which won in every line but Rh8 which lets white off the hook."
27.Rxh1 Nxe5 28.Qxe5 0-0-0?! It turns out that after 28...Bg7! 29.Rh8+ Black keeps his winning advantage with the following King march. 29...Kf7! 30.Rh7 Kg8 31.Rxg7+ Qxg7 32.Qxe6+ Kh8-+
29.Bc4 Qxd4+ 30.Qxd4 Rxd4 31.Bxe6+ Kd8?! Black has played a string of inferior moves and now only has a small edge. Best is 31... Kb8 32.Rh8 Rd8-+
32.Rh8 Ke7 33.Nc5 Rd2+ 34.Ke3 Rxb2 35.Bxf5 Bg7?!
35...Rxa2! Rf2+ 39.Kxg4 Rxf5 40.Kxf5 b2 41.Rc7+ Kf8 42.Rc8+ Ke7 Draw by perpetual. (42...Kf7? 43.Nd8+ Ke7 44.Rb8 b1Q+ 45.Rxb1 Kxd8 46.Rb7 Bd4+-) 36.Rb8 Bh6+? 36...Kd6 37.Rxb7 Kxc5 38.Rxg7 Rxa2 Again black has to give material but the theme is the same , just push pawns. White has very small winning chances.
37.Kd3 Kd6 The Bishop on b7 cannot be saved.
38.Kc4 Ba6+ 39.Nxa6 Rxa2 40.Nxb4 Rg2 41.Rc8 Ke5 42.Bxg4 Rxg3 43.Be2 Bd2 44.Nxc6+ Kd6 45.Rd8+?! With the exchange of material white will have a difficult time winning the position.
45...Kxc6 46.Rxd2 Re3 46...a5 47.Bd3 a4 48.Kb4 a3 49.Bb5+ Kb6 50.Ra2 Rg4+ A drawn position is inevitable
47.Bd3 Re5 48.Rh2 Re6 49.Rh5 a6 50.Rh7 Kb6 51.Kd5 Rf6 52.Rh1 Kc7 53.Be4 Kb6 54.Rb1+ Kc7 55.Kc5 a5 56.Rb7+ Kd8 57.Ra7 a4 58.Rxa4 Kd7 59.Bd5 Ke7 60.Ra7+ Kf8 61.Kd4 Rf2 62.Ke5 Re2+ 63.Kd6 Re7 64.Ra8+ Re8 65.Ra7 Re7 66.Ra1
"Murray did lose on time in the act of playing a move that lost anyway." (Lukey)
