1.Nf3 c5 2.c4 g6 3.e3 Nf6 4.d4 cxd4 5.exd4 d5 6.Nc3 6.cxd5 Nxd5 7.Bc4 6...Bg7 7.Be2 dxc4 8.Bxc4 0-0 9.h3 9.0-0 Bg4 10.Be3 Nc6 is a reverse Tarrasch 9...Nbd7 10.0-0 Nb6 11.Bb3 Nbd5 12.Re1 b6 13.Nxd5 13.Ne513...Nxd5 14.Bxd5 White didn't go for the pawn in the only other game in the database that I found from here. Instead, White was successful with 14.Bg5 in Gofshtein-Polaczek INT 2004 14...Qxd5 15.Rxe7 Bb7

with the two bishops and the isolated queen pawn firmly blockaded, Black has full compensation for the pawn. 16.Be3 The start of a bad plan. I wasn't giving Black enough credit for his compensation and protected the d-pawn because of the line 16.Qb3 Qxb3 17.axb3 Bxf3 18.gxf3 Bxd4 19.Raxa7 Rxa7 20.Rxa7 Rc8 with equality, but there is no reason for Black to exchange queens. He can play 16...Rfc8 intending Bf6 or even the immediate 16...Bf6. White's best is probably 16. Bf4 when Black has no troubles after 16...Rfe8 with compensation. 16...Rfc8 17.Qb3? continuing down the bad path. White should admit the previous move was bad and play 17.Bf4 17...Bf6 18.Rxb7 The rook is caught after 18.Qxd5 Bxd5 19.Rd7 Bc6 19.Rd6 Be7 so White loses the exchange. The only hope is that the passed d-pawn will provide some compensation 18...Qxb7 19.d5 Qa6 20.Rd1 Neither 20.Bg5 Bxg5 21.Nxg5 Qc4 22.Qf3 Rf8 23.Rd1 nor 20.d6 Qc4 does much 20...Qc4 21.Qa3 Qc2 22.Rd2 Qb1+ 23.Kh2 Rc2 24.Qd6 Bg7 24...Rxd2? 25.Qxf6+- 25.Rd4

25...Qxb2 Correctly resisting the bait 25...Bxd4? 26.Bxd4 Rc4 27.Nd2 Qd3 28.Be5 Re8 29.Nxc4 Qxc4 30.Qf6 Rxe5 31.Qxe5 and White is clearly better 26.Rf4 Rf8 27.Bd4 I spent most of my remaining time before playing this, but couldn't come up with any further tricks. 27.Nd4 Rc4 28.Nc6 Rxc6 29.Qxc6 Be5; 27.Qe7 Qxa2 28.d6 Qe6 27...Bxd4 28.Nxd4 Rxf2 29.Ne6 Rxg2+ 0-1
