1.e4g62.d4Bg73.f4d64.Nf3Bg4This is not a variation that strong players would try often. Dubov is very unconventional player and believes, that he can outsmart his lesser opponent on the unknown territory.5.c3Nd76.Bc4e67.O-O7.h3Bxf38.Qxf3Nb68…c69.f5exf510.O-Od511.exd5cxd512.Qxd5Qe713.Qxb7Rb814.Qxa7Ngf615.Bf4O-O16.Nd2Ra817.Qb7Nh518.Rae1+−1-0 (30) Pym,T (2099)-Dignam,M (2194) Douglas 20059.Bd3d510.e5Bf811.Be3h512.g3Qd713.Nd2c514.dxc5Na415.b4Nxc316.O-OQa417.a3a518.Rfc1axb419.Qf1Ra520.axb4+−1-0 (22) Matic,Z (2176)-Jurkovic, A (2339) Zagreb 20067.Be3Ngf68.Nbd2d59.Bd3dxe410.Nxe4Nd511.Bd2Qe712.h3Bxf313.Qxf3O-O14.h4c515.Nxc5Nxc516.dxc5Qxc517.h5Rfd818.hxg6hxg619.g4Rac820.Kf1Rd621.Re1Rcd822.Bb1Qb5+23.Kg1Qxb20-1 (23) Schlechter,C-Pillsbury,H Monte Carlo 19037.f5exf58.Qb3Qe79.Ng5fxe410.Nxf7Kf811.Nxh8Bxh812.Bxg8Nf613.O-O+−1-0 (45) Raedisch,P-Rossbach,M Kiel 20007…Ne77…Nb68.Bd3d59.e5Ne710.a4a511.Na3Qd712.b3O-O13.Nc2Rac814.Ne3Bxf315.Rxf3c516.Bb5Qd817.Bd2cxd418.cxd4Na819.Qe1b620.Ba6Rc721.b4Nc622.bxa5Nxd4=1-0 (90) Vucko,J (2187)-Babits,A (2270) Hungary 20057…c68.Nbd28.f5gxf59.h3fxe410.hxg4exf311.Qxf3Qe712.b4d513.Bb3f614.b5h515.bxc6bxc616.g5f517.Qf4Nf818.Ba3Qd719.Re1Ne720.Nd2±1/2-1/2 (39) Novak,I-Trapl,J Harrachov 19668…Qc79.b4Ngf610.Bd3Nh511.Nb3Nxf412.Bxf4O-O13.Qe1e514.dxe5Bxf315.Rxf3Nxe516.Rh3Nxd317.Qh4h518.Rxd3+−1-0 (44) Rodriguez Dorado,V-Gomez Velasco,J Valladolid 19978.Qe18.h3Bxf39.Qxf3O-O10.e510.f5exf511.Bg5Kh812.Bxe7Qxe713.exf5c614.Nd2Rae815.Rf2d516.Bd3Qe317.Nf1Qxf318.Rxf3Bh619.Ng3Re7⩱1/2-1/2 (55) Levi,E (2215)-Ker,A (2300) Melbourne 198910…d511.Bd3c512.Be3Qb613.Qf2c414.Be2Qxb215.Nd2Qxc316.Nf3Qa517.g4f618.Qh4g519.Qh5gxf420.Bxf4Ng6−+0-1 (24) Metz,H-Zysk,R (2400) Baden-Baden 19878.Be3O-O9.Nbd2c510.h3cxd411.cxd4Bxf312.Qxf3Nb613.Bb3d514.e5Qd715.Rfc1Rfc816.Rc5Rxc517.dxc5Na418.Bxa4Qxa4⩱0-1 (52) Bonnaire,R-Zunker,R (2165) Bad Wildungen 19988.Bb3O-O9.Be3d510.e5Nf511.Bf2f612.Nbd2Bh613.g3fxe514.dxe5g515.c4c616.cxd5cxd517.fxg5Bxg518.Nxg5Qxg519.Nf3Qh520.Bxd5exd521.Qxd5+Kh8−+0-1 (55) Ponizil,C (2478)-Petenyi,T (2454) Czech Republic 20178…O-O9.Bb3The first part of the opening phase is over and Black must be especially careful about his potentially stranded bishop on g4.9.Nbd2c510.Bb3cxd411.Nxd4Nc512.Bc2e5=9…Bxf310.Rxf3c511.Be3cxd412.cxd4Trading the bishops on d4 might have some merit, but White would be practically forced to sacrifice the pawn.12.Bxd4Bxd4+13.cxd4Qb614.Kh1Qxd415.Nc3⯹12…Nf613.Nc3Ng414.Rd1Qb614…d515.e5Nxe316.Qxe3Rc8=15.Na4The fight is obviously concentrated around the d4-pawn.

The attack against the d4-pawn loses its merit and the black pieces are scrambling to get coordinated again.18…h5!?19.Qxe7Bf620.Qd7a621.Bxe6Bxd4+21…Rad822.Bxg4±22.Kh1Nf623.Bxf7+Rxf724.Qh3Bxc325.Be3Qc626.bxc3±18…Bxd4+19.Kh1Nf2+20.Rxf2Bxf221.Qxe7b422.Na4Qd823.Qg5!±19.g4!Qb720.Rh3h5?Defence in chess is an art that very few top players have mastered properly. The radical move with the h-pawn is objectively bad, but it must be admitted that Dubov was under intense pressure.20…h6!21.e5dxe522.dxe5Nh723.f5gxf524.Bxh6Ng625.Qh5fxg426.Qxg4±21.gxh5Nxh522.f5!exf522…d523.Bg5Nc624.f6Bh825.exd5+−23.exf523.Bg5Rae824.Bxe7Qxe725.Qxe7Rxe726.exf5Kh727.Nxb5±23…Nxf524.Qg5A fine move that hints at the numerous problems Black is experiencing with his pieces. The knights on f5 and h5 are vulnerable, but it is the soft g6-pawn that causes the catastrophe of the black position.24…Ne724…d525.Rxh5Rac826.Nxd5+−25.Rxh5!gxh526.Rd2d5Completely desperate attempt to close the diagonal a2-g8 as it prevents Black from even dreaming about a sufficient defence.26…Qb627.Qxe7Qd828.Qxd8Raxd829.Nxb5+−26…Qf327.Rg2Nf528.Bd5Qd329.Be4Qxd4+30.Kh1Ne731.Bxa8+−27.Nxd5Rfe827…Rfc828.Nxe7+Kf829.Ng6+Kg830.Rg2+−28.Rg2White was very efficient in opening up the kingside, the defender can only choose the form of honourable undoing.28…Ng628…Nf529.Qxf5Re1+30.Kf2Rxc131.Qf6+−29.Nf6+Kf829…Bxf630.Qxg6++−30.Nh7+Kg831.Qxg61–0
