Round 4 Board 4

1.g3 g6 2.Bg2 Bg7 3.e4 e5 Previously, I had always played 3...c5 in this position. However, I won a nice game in a symmetrical Vienna against Corey Acor at the US Amateur Team South earlier in the year, so I decided to go for that structure instead. 4.Nc3 Nc6 5.d3 d6 6.f4 Nge7 7.Nf3 0-0 8.0-0 h6 9.Be3 Nd4 10.Qd2 Kh7 11.Nh4 Bent Larson beat Oscar Panno with 11.Rae1 in the supertournament at Palma de Mallorca in 1969. 11...exf4 12.gxf4 f5 12...Be6 13.f5 with initiative; but Black could go for the immediate 12...Nec6 when it isn't clear that White has anything better than the retreat a la Larsen 13.Nf3 13.Rae1 Be6 14.Nd1 Nec6 now White can initiate tactics based on the position of Nd4 15.Nxg6

15...Kxg6 16.c3 The point, Black's knight does not have a good retreat 16...Bxa2 16...Nb5 17.a4 is better for White 17.cxd4 Nxd4 18.exf5+ Nxf5 19.Bxb7 Rb8

20.Be4 I asked him afterwards about 20.Bxa7 Rxb7 21.Qg2+ Kh7 22.Qxb7 c5 He said he didn't seriously consider it. Indeed, Black has comfortable compensation with ideas like Qh4, Rf7, Bd4, and the rook to the g-file, but the engine only rates it a minimal advantage to Black. 20...d5 21.Bxf5+ Rxf5 22.d4 Bb1 23.Nc3 Be4 24.Nxe4 dxe4 25.Qg2+ Kh7 26.Qxe4 Qd5 27.Qxd5 Rxd5!

White has an extra pawn, but all of his pawns are isolated and weak. 28.Rc1 28.f5 might be a slightly better try taking away g6 from the Black king 28...Bxd4 29.Bxd4 Rg8+ 30.Kf2 Rxd4 31.Ke3 White is more active than in the game, but he doesn't have a material advantage and the game should still end in a draw. 28...Bxd4 29.Rxc7+ Kg6 30.f5+ Kf6 31.Rc6+ Kf7 32.Bxd4 Rxd4! 33.Rxh6 33.Ra1 Rxb2 34.Rxa7+ Ke8! and because of White's weak back rank, the best he can do is the pawn up ending after 35.Rc8+ Rd8 36.Rxd8+ Kxd8 which Black should have little trouble holding. 33...Rxb2 34.f6 Rdd2 35.Rh7+ Kf8 35...Kg8 makes Black do a little more work to earn the draw 36.Rg7+ Kf8! (36...Kh8?) 37.h4 (37.f7 Rf2!) 37...Rh2! 38.Rg4 Kf7! 36.f7 Now white has nothing after 36.Rg7 Rxh2 36...Rg2+! 37.Kh1 Rgf2 38.Rc1 Rbc2 39.Rb1 Rb2! 40.Rc1 1/2-1/2
