1.d4 f5 2.Nc3 Nf6 3.Bg5 d5 4.f3!? [ With intentions of carrying the game toward territories of the Staunton gambit. It is more typical 4.Bxf6 exf6 5.e3 which is an intent of limiting Black's counterplay. It could continue 5...Be6 ( also it may be 5...c6 6.Bd3 Bd6 7.Qf3 g6 8.h3 Qe7 9.Nge2 where White is owner of a small superiority) 6.Bd3 Nc6 with intentions of attacking the bishop from b4 7.a3 Qd7 8.Nge2 0-0-0 9.Nf4 Bf7 10.Qf3 Kb8 11.0-0-0 with reciprocal chances, according to Zarubin,P-Cherniaev,A Cherepovets 1993] 4...c6 [ A deviation that seeks to fight against the possibility of the advance e4, is 4...Nc6 that it can be continued with 5.Qd2 e6 6.0-0-0 Bb4 7.Nh3 0-0 8.a3 Ba5 9.e3 Ne7 10.Nf4 Agrest,E-Jakubiec,A Griesheim 2003, where the white pieces maintain the opening advantage] 5.e4 fxe4 [ It doesn't seem to be fully justified, not accepting the challenge with 5...Qb6 since after 6.e5 Nfd7 7.a3 e6 8.b4 the first player commands the actions] 6.fxe4 dxe4 7.Bc4 [ Once the pawn has abandoned its location on d5, the bishop occupies the Standard position, but it also deserves consideration the move of Ilya Rabinovich 7.Qd2!? ] 7...Bg4 [ I find inferior 7...Bf5 8.Nge2 Nbd7 9.0-0 Bauer,C-Tseitlin,M Bad Zwesten 1997, where White clearly surpass his opponent in development] 8.Qd2 Nbd7 9.h3 Bh5 10.Nge2 [ It is an option to consider 10.g4 Bg6 11.0-0-0 as was played once by Genadij Timoscenko] 10...e5 [ If 10...Nb6 the knight moves away of supporting the dots of central rupture, and after 11.Bb3 White pieces stay with an excellent game] 11.0-0-0 exd4?

[ A clear conceptual error. Who is worse developed should have much care with the opening of lines, stiller with the king semi-caught in the center lines. Better it would be something like 11...Be7 although anyway White has a certain advantage. For the benefit of John, we ought to highlight, that taking in d4, is the theoretical recommendation, giving the game that it is mentioned in the following comment as antecedent. In passing, it is also good to mention that it is the main option of the engine (a brief discussion on this topic can be found at ¡¡Vade retro .eng!!)] 12.Nxd4!N [ Nourished in the game De Laat,P-Simmelink,J corr 1994, some "theoretical" sources affirm, that with this variant White gets nothing of the opening. That encounter continued with: 12.Qxd4?! Bc5 13.Qd2 Qe7 etc.] 12...Nb6 [ The exchange cannot be captured unpunishedly, because after 12...Bxd1 13.Ne6 the problems are practically unsalvageable. Let us see some example variants: 13...Qc8 ( neither 13...Qa5 14.Rxd1 threatening 15.Qf4 14...Ne5 15.Qd4 h6 ( 15...Nxc4? 16.Bxf6+- ) 16.Bxf6 gxf6 17.Nxe4 Be7 18.Nd6+ Bxd6 19.Qxd6 and the knight jump to g7, or if it is avoided, to c7, doesn't offer opportunities to continue) 14.Nxe4!? with varied threats, of those which, the main one is 15.Nxg7+ 14...Nxe4 15.Qf4 threatening mate in two, and turning difficult to find any move that satisfactorily protects Black 15...Nef6 ( 15...Nxg5 16.Nxg5 Bh5 17.Re1+ Kd8 18.Ne6+ winning immediately) 16.Re1! Be7 17.Nxg7+ Kd8 18.Bxf6 ( 18.Rxe7!? ) 18...Bxf6 ( 18...Nxf6 19.Rxd1++- ) 19.Ne6+ Ke8 20.Nc5+ Kd8 21.Rxd1 and Black is lost] 13.Bb3! [ Certainly, it was not my intention to continue wretchedly with 13.Be2 although objectively speaking, White gets with it a light supremacy] 13...Bxd1

[ Now, that it isn't convenient to go with the knight to e6, due to the change of queens, the capture of the exchange, seems the most suitable thing. An alternative could be 13...Bb4 but it isn't good, because after: 14.Qe3! Nbd5 ( not 14...Bxd1 through 15.Nxe4+- ; neither 14...Bxc3 because of 15.Nf5+- ) 15.Nxd5 cxd5 16.Ne6 White gets an overpowering advantage] 14.Qxd1! [ I thought this movement a lot of time, because apparently, there was a convincing onslaught, after: 14.Re1!? with the naive, but murderous threaten of 15.Nxe4 14...Bb4!! ( for appreciating in its correct gauge the power of the defense with the b4 pin, we can develop a little the events that would take place whether it was tried to protect "e" with 14...Be7 15.Nxe4 Bxc2 ( 15...Nbd5 16.Ne6 Bxc2 ( 16...Qd7 17.Nxg7+ Kd8 18.Nxf6+- ) 17.Bxd5!? Nxe4 18.Nxg7+ Kd7 19.Bxe4+ Kc8 20.Bxe7 Qxd2+ 21.Kxd2 Bxe4 22.Rxe4 and Black has survived to the attack, but it won't do the same in the ending; 15...Nxe4 16.Rxe4 Nc8 17.Qb4! Rf8 ( 17...Bxc2 18.Kxc2+- ) 18.Bxe7! ( less clear is 18.Qxb7? Rf1 ) 18...Nxe7 19.Ne6 and the endurance came to its end) 16.Kxc2 Nbd5 ( 16...Nfd5 17.Bxe7 Nxe7 18.Ng5+- ) 17.Nf5 Kf7 ( 17...Nb4+ 18.Kb1 Qxd2 19.Nxd2 Nfd5 20.Bxe7 Nd3 21.Re4 with a great advantage; 17...Bb4 18.Nxg7+ Kd7 19.Qf2+- ) 18.Nxf6 Bxf6 19.Bxf6 Qxf6 ( 19...Kxf6 20.Qd4+! Kxf5 21.Qg4+ Kf6 22.Qe6+ Kg5 23.Re5+ and the checkmate is imminent; 19...gxf6 20.Qh6+- ) 20.Bxd5+ cxd5 21.Qxd5+ Kf8 ( 21...Kg6 22.Ne7+ Kh6 23.Re6+- ) 22.Re6 winning) 15.Bxf6 Qxf6 ( it is worse 15...Bxc3 16.Rxe4+ Kd7 17.bxc3 with a powerful attack) 16.Rxe4+ Be7 ( it isn't healthy 16...Kd7 17.Ndb5+ Kc8 18.Be6+ Kb8 ( 18...Qxe6 19.Rxe6 cxb5 20.Qd4!+- ) 19.g4! with idea of 20.Qh2 19...Be2[] 20.Qxe2 Qh6+ 21.Kb1 and Black is lost) 17.Ne6 and the white pieces have more than enough compensation for the sacrificed material, but in spite of their advantage, it is still necessary to play a lot. This defense with the Bb4 pin, is also the justification to capture in d1 with the Queen, instead of the more natural with the Rook, in the fourteenth move of the actual game] 14...c5 [ A desperate effort to alter the course that the events have gone taking. The alternative was to continue with the deferred development of the forces with 14...Be7 however 15.Re1 faces Black with shortage of resources to confront its fate. For example: 15...Nbd5 16.Nxd5! cxd5 ( 16...Nxd5 17.Rxe4+- ) 17.Ne6 Qd6 ( in the event of 17...Qa5?! it would continue 18.Bxf6 Bxf6 19.Bxd5 with intentions of taking e4 with the Rook, and if now 19...Qb6 then, simply 20.c3 e3 21.Qd3 and the resistance collapses hopelessly) 18.Bxf6 Bxf6 19.Rxe4 Kd7 20.Bxd5 and the position, is profiled as very advantageous for White] 15.Bxf6 Qxf6 [ Against 15...gxf6 follows the winning 16.Qh5+ ] 16.Ne6 Once again, the charger, like a sharpened dagger, is incrusted in the heart of the black position 16...Qh6+ 17.Kb1 Rc8 [ After: 17...c4 18.Nc7+ Ke7 19.N3d5+ the attack is unstoppable] 18.Nxe4! With the primordial intention of giving a check in d6 18...c4 [ It doesn't operate 18...Nd7 due to 19.Re1 This subject is repeated with some other moves, too] 19.Nxf8 After this direct and powerful blow, Black is ousted 19...Rd8 [ It doesn't help 19...Rxf8 because 20.Nd6+ wins; and in the event of 19...Kxf8 20.Nd6 with the threat of 21.Rf1+, is as much as the previous line] 20.Qe2 [ After 20.Qe2 Kxf8 ( It doesn't work 20...cxb3 21.Rf1 and the discovered checks, triumph; neither 20...Rxf8 because of 21.Nc5+ Kf7 22.Bxc4+ and there is not possible answer) the prosaic but effective 21.Rf1+ Ke7 22.Nc5+ Kd6 23.Nxb7+ Kc7 24.Nxd8 Rxd8 25.Bxc4 lowers the curtain of the last act] 1-0
