Picture taken at the Nelson International Open 2007
1.c4 The scene was set for what could only be a critical match-up, if either player was to win he would have excellent chances to Win the tournament.
1...e5 2.g3 d6 A round earlier Dive defeated Ker with a similar setup to the game continuation. With this in mind Chandler had an excellent source for his preparation and must have been feeling good after the opening. Dive's Dogmatic approach to his seemingly favourite line of the English cannot easily be faulted. He only really made one error to lose the game, to forsee the power of black's 21st move is by no means easy. 2...f5 3.Bg2 Nf6 4.Nc3 Be7 5.Rb1 Nc6 6.a3 a5 7.d3 0-0 8.e3 Kh8 9.Nge2 Qe8 10.Nd5 Nxd5 11.Bxd5 Qh5 12.Bg2 Nd8 13.0-0 Ne6 14.b4 g5 15.Bb2 Bf6 16.d4 e4 17.d5 Ng7 18.d6 axb4 19.axb4 Bxb2 20.Rxb2 Rf6 21.c5 cxd6 22.cxd6 Qg6 23.Rd2 Ne8 24.Qc2 Rxd6 25.Nd4 g4 26.Qb2 Ng7 27.Ra1 Rda6 28.Rc1 Rc6 29.Nxc6 bxc6 30.b5 cxb5 31.Qxb5 Qa6 32.Qxa6 Bxa6 33.Ra2 Ne8 34.Bf1 Rc8 35.Rxc8 Bxc8 36.Ra8 Nd6 37.Ba6 1-0 Dive,R-Ker,A/Auckland 2008.
3.Bg2 f5 4.Nc3 Nf6 5.Rb1!? Be7 6.b4 In my opinion It is debatable wheather white's approach can guarantee any advantage but Dive's experience in the line would count for alot more than a theoritical frown. [6.d3 0-0 7.Nf3 Qe8 8.b4 Qh5 9.b5 Nbd7 10.a4 Nc5 11.Be3 e4 12.Bxc5 dxc5 13.Nd2 exd3 14.e3 Qxd1+ 15.Rxd1 a6 16.0-0 axb5 17.axb5 Rd8 18.Ra1 Rxa1 19.Rxa1 b6 20.Nd5 Nxd5 21.Bxd5+ Kf8 22.Kf1 Bd7 23.Ke1 Bxb5 24.Ra7 Rxd5 25.cxd5 c4 26.Ra8+ Kf7 27.Nf3 Bb4+ 28.Kd1 Ba5 29.Ra7 Ke7 0-1 Zhu Chen-Rotstein,A/Cannes 1997.
6...0-0 7.d3 Kh8 8.Nf3 c6 9.0-0 Qe8 So far I believe both players are deep in preparation. 10.Qc2 Qh5 11.c5?! Perhps white is a little too eager to break black's center down. [11.b5!? Why not continue with prying open black's Q-side.11...cxb5 (11...f4?! 12.gxf4 Bh3 13.Bxh3 Qxh3 14.bxc6 bxc6 15.Bd2 Nbd7 16.Qa4 White has the better of it but not by alot. 16...Nc5 17.Qxc6 Rac8 18.Qb5 e4 19.dxe4 Nfxe4 20.Nxe4 Nxe4 21.Kh1 Nxd2 22.Nxd2 Rxf4 23.Rb3) 12.Nxb5 Nc6 13.Ba3 e4 14.Nfd4 Nxd4 15.Nxd4 e3 16.f4 Ng4 17.h3 Nf2 18.Kh2 Rf6 19.Rxf2 The position is dynamically balanced according to my PC)
[11...dxc5 12.bxc5 Nbd7 13.Na4 Black has to be better in this position, he has a nice K-side attack in the making where white is stuck to defence on both side's of the board and cannot easily break through on the Q-side 12.gxf4 Bh3 13.Bxh3 Qxh3 14.bxc6 bxc6 15.Bd2 Nbd7 16.Qa4 White has the better of it but not by alot. 16...Nc5 17.Qxc6 Rac8 18.Qb5 e4 19.dxe4 Nfxe4 20.Nxe4 Nxe4 21.Kh1 Nxd2 22.Nxd2 Rxf4 23.Rb3] 12.cxd6 Bxd6 13.Rd1 fxg3 14.hxg3 Ng4 15.Ne4 Be7 16.Bg5 Bxg5 17.Nexg5 Bf5 18.Ne4 Nd7 19.Nd6 Be6 20.Nxb7 Bd5
21.Rb2? This is the losing move
[21.Nc5! After this move Black is just a pawn down with insufficient Compensation. It makes sense to bring a loose piece back to safety and it proves to be a valuable piece in defence all with tempo as black's knight on d7 must make a decision. 21...Nxc5 (21...Rxf3 22.exf3 Nh2 23.Ne4+-) 22.Qxc5 Rxf3 (22...Nf6 23.e4 Bxa2 24.Ra1 Be6 25.Nxe5+-) 23.Bxf3 Qh2+ 24.Kf1 The queen protects the mate on f2]
21...Rxf3!! This exchange sac is just crushing.
