2011 Turner UTD GM Invitational
[Annotator: Sadorra]

1.e4 e6 2.d4 d5 3.Nd2 Be7 4.e5 c5 [4...Nh6 5.c3 ] 5.Qg4 g6 [more common in practice is 5...Kf8 this was pioneered by Morozevich, who I believe is the most creative player in the chess world. As inspired as I could be by this player, I didn't want to go down this road because it has tested many times by grandmasters and therefore well-studied. 5...g6 has been played before but I believe there is still much room for exploration.] 6.dxc5 [6.Qd1 Nc6 7.Ndf3 (7.Ngf3 cxd4 8.Nb3 ) 7...cxd4 8.Ne2 Qa5+ 9.Bd2 Qb6 ] 6...Nh6! According to my database this is a novelty. I gave it an exclamation mainly for practical reason and surprise value. 7.Qf4?! During my preparations and on the board, this move didn't make much sense to me. I think it is Black who only benefits with my pawn on g5. [7.Qh3 is a better retreat, and only time will tell the true assessment of this new line.] 7...g5 8.Qa4+ Bd7 forcing Bb5. I must take advantage of the vulnerability of the exposed White queen. [8...Nc6 9.Ndf3! Nf5 10.Bd3 ] 9.Bb5 Nc6 10.Ndf3 a6 11.Bxc6 Bxc6 12.Qb4 [12.Qd4 with the idea to go back to the ideal d1-square, but fails due to his lag in development. 12...Nf5 13.Qd1 d4-/+ ; 12.Qa3!? may be relatively better but after 12...Nf5 13.g4 Nh4 14.Nd4 Qc7 and Black is still better because White is riddled with various forms of weaknesses] 12...a5 if it wasn't for this "shoving" move, White would be okay due to his control of the important d4 & c5 squares. Unfortunately, my a-pawn was territorial towards her queen. 13.Qd2 d4! [At first I was intending to play 13...Nf5 14.Ne2 (14.g4 Nh4 ) 14...d4 (14...g4 15.Nfd4 ) 15.Nexd4 Nxd4 16.Qxd4 (16.Nxd4 Bxg2 17.Rg1 Qd5 18.Qe3 Bxc5 19.c3 h6 ) 16...Bxf3 17.Qxd8+ Rxd8 18.gxf3 Rd5 I may still be better, but why cash in all the advantages of my position right away?] 14.h4 White tries to create counterplay. 14...Nf5! 15.hxg5 forced due to the threat of g5-g4. 15...Bxc5 16.Ne2 Qb6 Here, I believe that Black already has a decisive advantage. Though, White may have defensive resources, I only have to calculate lines accurately to make my attack decisive. 17.Nf4 [after 17.0-0 one line that leads to win is 17...Bxf3 18.gxf3 h6 19.Ng3 Nh4 20.Qf4 hxg5 21.Qf6 Rg8 22.Ne4 Be7-+ ] 17...Bb4 18.c3 dxc3 19.bxc3 Rd8 20.Qb2 Bxf3 21.0-0!? an attempt to confuse me. [21.gxf3 is what I anticipated and intend to meet with 21...Qc6!? (or 21...Qd4 22.Bd2 Qxe5+ 23.Ne2 0-0 and Black's attack persists.) ] 21...Rg8 leave the hanging pieces alone! Let him make the decision:) 22.gxf3 [22.g6 Bxg2 23.gxh7 (23.Kxg2 Qc6+ 24.f3 Bxc3 ) 23...Ke7 24.hxg8Q Rxg8 25.Nxg2 Nh4 and Black's attack crashes through.] 22...Rxg5+ 23.Ng2 Rg6 24.cxb4 Nh4 25.Bf4 Nxg2 26.Bh2 Ne1+ 27.Kh1 Qc6 and White resigns as the Black pieces slowly approach and surround his vulnerable king while his army is hopelessly divided. A possible finish would be 28. Qe2 Nxf3 29. Rac1 Rh6! 30. Kg2 Ne1 31. Kg3 Qg2 32. Kf4 Rh4 mate. 0-1
