Gone awry: instructive loss in the Rossolimo Sicilian


My first chess coach, FM John Curdo, liked to call this variation the "Awry Lopez."

More popular and less risky is 7.Nc3!?

The stem game, with 11...exd6, is Gabor Kadar (2280) vs. Lajos Seres (2430), Hungarian Championship 1994/95: 11...exd6 12. Ne4 Qb6 13. Bxc6 Qxc6 14. Bg5 Qb6 15. Qd3 Rfe8 16. Nfd2 h6 17. Bh4 f5 18.

A new attempt by Julian Estrada Nieto (2285) vs. Misa Pap (2512) Budapest, May 5, 2011, continued 11.Bg5 (instead of 11.exd6) 11...dxe5 12.Bxc6 bxc6 13.Nxe5 Rc8 14.Nf3 Re8 15.h3 Nxc3 16.bxc3 c5 17.Be3 Bd5 18.Ne5 Qa5 19.Nd3 cxd4 20.Bxd4 Rxc3 21.Bxg7 Kxg7 22.Nf4 Bc6 23.Qd2 Ra3 24.Qb2+ Qc3 25.Qe2 Qf6 26.Qg4 Kh8 27.Rac1 Rxa2 28.Qg3 Ra4 29.Nd3 Ra3 30.Re3 Ra1 31.Rxa1 Qxa1+ 32.Kh2 Bd5 33.Qc7 Qf6 34.Qxa7 Qd6+ 35.Kg1 f6 36.Qd4 e5 37.Qc3 Rb8 38.Qc2 Kg7 39.Re1 Be6 40.Ra1 Rb3 41.Ra7+ Kf8 42.Ra8+ Rb8 43.Qc5 Qxc5 44.Rxb8+ Qc8 45.Rxc8+ Bxc8 46.f3 g5 47.g4 Ke7 48.Kg2 Kd6 49.Nf2 f5 50.gxf5 Bxf5 51.h4 gxh4 52.Nh3 Ke7 53.Ng5 0-1. To play over the game, go here.

11...Qxd6N 12.Bg5


Nieto's novelty delayed a move. I wasn't aware of the Nieto-Pap game, of course, since it was played seven months after this encounter. I believe the game is still playable at this point, although I will probably choose 7.Nc3 from now on.

12...h6 13.Nxd5

The proper follow-up is 13.Bh4 keeping the tension in the position. I did not fare well after the upcoming exchanges.

12...hxg5 14.Bxc6 bxc6 15.Nc3 Bg4 16.Ne4= Bxf3 17.Qxf3 Qxd4 18.Nxg5 Qxb2 19.Qxc6 Qf6 20.Qb5 Rab8 21.Qa5 Qc3 =/+ 22.Qa6 Qc5 23.Ne4 Qc8 24.Qxc8 Rfxc8 25.Rac1 Rxc1 26.Rxc1 Bh6 27.Ra1 f5 28.Nc3 Rb2 29.Rb1

If 29.Nd5 Kf7 (29...e6 30.Ne7+ Kf7 31.Nc6 Kf6 32.g3 and black is better) 30.Kf1 e6 31.Ne3 Bg7 32.Rc1 favoring black.

29...Rd2 30.Rd1 Rc2 31.Nd5 Kf7 32.Nb4


The material is even, but the a-pawn is vulnerable and will soon be lost. With an open board and pawns on both wings, the bishop supported by the more active rook is much more effective. My opponent will not give me any chances for counterplay.

32...Rb2 33.a3 Rb3 34.Nc6 Rxa3 35.g3 Bg5 36.Rd7 a6 37.Rd5 Bf6 38.Kg2 Rb3 39.Nd8+ Ke8 40.Ne6 Rb6 41.Nc5 e6 42.Rd2 Be7 43.Na4 Rb4 44.Ra2 a5 45.f4 Kd7 46.Kf3 Kc6 47.Rc2+ Kd5 48.Nc3+ Kd6 0-1


The position is hopeless due to the outside passed pawn. Black can also make the e-pawn a passer without allowing my g- and h-pawns to safely advance, so I resigned rather than wait for the inevitable. Since this was a correspondence game, I spent a couple of days looking for tricks. The following line took away all of my optimism: 49.Ke2 g5 50.fxg5 Bxg5 51.Ra2 Bf6 52.Na4 Rb3 53.Rd2+ Kc6 54.Rc2+ Kb5 55.Nc5 Rb4 56.Nd3 Rc4 57.Ra2 a4 58.Kd2 Bc3+ 59.Kc1 Bd4+ 60.Kb1 e5 61.Rg2 a3 62.Ka2 Rc3 63.Ne1 Kc4 64.Nc2 Bc5 65.Ne1 f4 66.gxf4 exf4 67.Rg4 Be3 -+.

As a result of this game I undertook a serious study of rook and minor piece endgames, not only to learn how to play them better, but more importantly to understand when the position may devolve into an inferior endgame of this type. Such positions are more common than I previously understood. Knowing when to steer away from materially equal but theoretically inferior lines, or encourage an unaware opponent to drift into the kind of superficial liquidation that I demonstrated in this game, is critical to overall chess improvement. It will require work, but will be worth the time invested.
