Round 3, Board 2

1.e4 I was having some issues with some of my lines with 1.d4 so I experimented with 1.e4 in this tournament. 1...c5 2.Be2!?

This move was the topic of one of Jeroen Bosch's SOS columns in New In Chess. However, this was probably not a big surprise to my opponent as I had played the same line in the previous round against Rochelle Wu. 2...g6 3.f4 Bg7 4.Nf3 Nc6 5.0-0 d6 6.c3 Nf6 7.d3 0-0 8.Qe1 Vladislav Kovalev has played quite a few games in this variation and his preference here is 8.Kh1 when Bosch gave 8...c4 9.Be3 (Kovalev played 9.Nbd2 the one time he reached this position.) 9...cxd3 10.Bxd3 as being about equal; 8.Na3 is the most popular here 8...c4 9.Na3 I played 9.Qh4 against Wu but didn't get much out of the opening so I decided to develop my pieces instead 9...cxd3 10.Bxd3 Rb8 11.Kh1 a6 12.Qh4 Switching back to the attacking plan. It was better to complete development with 12.Nc2 b5 13.Be3 12...b5 13.f5 b4 14.Nc2 bxc3 15.bxc3 Ne5 16.Nxe5 dxe5 17.Rf3

17...Qc7 Afterwards he pointed out 17...Bxf5 18.exf5 e4 19.Bxe4 Qd1+ 20.Ne1 g5 21.Bxg5 Qxa1 which should be very good for Black 18.c4 Rd8 19.Bg5 Bxf5 This isn't as strong as before. White's attack really isn't going anywhere after 19...gxf5 20.exf5 e4 21.Rh3 Rxd3 Stronger was 21...exd3 22.Bxf6 Bxf6 23.Qxh7+ Kf8 24.fxg6 Qxc4 and Black is winning 22.Ne3 Rxe3?! 22...Qe5 23.Bxe3 Qxc4 24.Rc1 Qxa2 25.Bg5 Qb2 26.Rhc3 Rf8 27.Rc8 Qe5 28.fxg6 hxg6 29.Rxf8+ Bxf8 30.Re1 bettter is 30.Rc8 and Black has to figure out if he has anything better than repeating moves with 30...Qa1+ 31.Rc1 Qe5, but it is difficult to abandon the back rank when the clock is starting to tick down. 30...Nh7 31.Bh6 Trading bishops doesn't really accomplish much for White. I should have retreated. 31.Bf4 31...f5 32.Bxf8 Nxf8 33.Rc1 e3 34.Qc4+ Qe6 This surprised me. I thought he would keep the queens on. However, the ending holds no dangers for Black, so he is playing for two results. 35.Qxe6+ Nxe6 36.Kg1 36.Rc6 Nd4 37.Rxa6? e2 36...Kf7 37.Rc6 a5 38.Ra6 Nd4 39.Rxa5 Kf6 40.Kf1 f4 41.Rd5 e5 42.Ke1 Kf5 43.Rc5? White's goal should be to prevent e4, so the correct move is 43.Ra5 g5 (43...Ke6 44.Ra6+ Kd5 45.Rxg6 e4 46.Rg5+ Ke6 47.Ra5 Nc2+ 48.Ke2 and unlike what happens in the game the White pawn on g2 prevents f3+) 44.h3 Ke6 45.Ra6+ Kd5 46.Ra5+ 43...Ke4 better is 43...Ke6 with the idea of e4 since White has no check on the sixth rank. 44.Rc3? Preventing Kd3, which isn't a threat. White had to keep the e-pawn under fire with 44.Ra5 when it seems there is a chance to defend. 44...Kd5 Now Black gets ...e4 and the rest should be easy, but the endgame still takes a couple of more twists and turns. 45.Rc8 e4 46.Re8 g5 47.h3 to stop g4 and f3, but creating a big weakness on g3. 47...Ne6 Black isn't ready to go directly for the hole 47...Nf5? 48.Rg8! f3 49.gxf3 exf3 50.Rxg5! Ke4 51.Rg4+ Kd3 52.Rg8!= 48.Ke2 Ke5 49.Re7 Kf6 50.Rd7 Ng7 51.g4 not a move I wanted to play, but White can't really allow Nf5-g3

51...Ne6? This move looks logical. Black wants to check on d4 to drive the White king back and advance his pawns. From e6 there is also the route c5-b3 ready to check on either d4 or c1 as occurs in the game. On top of everything else, the knight covers g5 freeing the king from the defense of the pawn. So all in all it seems like a perfect move. However, the rook should be able to defend against the various knight jumps. There is another square the knight can land on to support the advance of the pawns, d5. He has a direct route to there with 51...Ne8! because the king has access to e6 in order to assist 52.Rd5 Ke6! 53.Rxg5 Nf6 52.Rd5! Nc7 If Black tries to return, White has a surprising defense. 52...Ng7 53.Rc5 Ne8 54.h4! gxh4 55.Rf5+ 53.Rc5! 53.Ra5? Ke6! 53...Ne6 54.Rd5 Kg7 54...Ke7 55.Re5 Kd6 56.Rxe4 Kd5 57.Ra4 Nd4+ 58.Kd3! Nb3 59.Ke2! Nc1+ 60.Kf3! also holds 55.Rd6 Nc5

56.Rd5? Falling for the temptation of the g-pawn. 56.Rd4 Kf6 57.Rc4! wins the e-pawn and should draw without trouble 56...Nb3-+ 57.Rxg5+ Kh6 58.Rd5 Nc1+ 59.Kd1 f3 The move I had missed. White can't stop the Black pawns. 60.Kxc1 f2 61.Rd6+ Kg7 62.Rd7+ Kf8 0-1
