CBM 209 : especial con Anna y Mariya Muzychuk

por ChessBase Shop - la tienda online de ChessBase
05/09/2022 – Las dos "heroínas" de la edición no. 209 de revista ChessBase Magazine ya se conocían antes de que siquiera hubiese comenzado la Olimpiada de Ajedrez en Chennai, donde las hermanas ucranias Anna y Mariya Muzychuk conquistaron la medalla de oro junto con su equipo. Desde luego, eso es una razón más por dedicarles un homenaje. El nuevo número de la revista digital de ChessBase inluye una selección de 21 partidas comentadas con detalle y un artículo sobre estrategia, escrito por GM Mihail Marin titulado "Las hermanas Muzychuk" y además un especial relacionado con los finales de partidas, escrito por GM Karsten Mueller (ambos artículos incluyen vídeos). Krisztian Szabo ha elegido la partida Mariya Muzychuk vs. Alexander Bagrationi (2018) para su análisis - seguramente también por el "gran final". ¡Échenle un vistazo!

CBM #209: especial con Anna y Mariya Muzychuk

Mariya Muzychuk – Alexander Bagrationi (Jerusalem Japhet Memorial op 4th (7), 06.07.2018)

Análisis a cargo de Krisztian Szabo (en inglés)

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 Nc6 6.Bg5 Bd7

Less common choice than 6...e6.

7.Qd2 Rc8 8.0–0–0 8.f4!? is the most ambitious way, 8...Nxd4 9.Qxd4 Qa5 10.e5! dxe5 11.fxe5 e6 12.0–0–0 with 300+ games at this moment.

8...Nxd4 9.Qxd4 Qa5 10.f4 10.Bd2!?

10...h6

10...Rxc3!? is the typical exchange sacrifice. Most of the times we see this idea in the Dragon, but in other Sicilians are also common. 11.bxc3 (White cannot exchange the queens with 11.Qxc3? Qxc3 12.bxc3 Nxe4 and Black has a good position.) 11...e5 and Black usually has a great play for the exchange.

11.Bxf6 gxf6 12.Kb1 Qc5 Offers a queen trade.

13.Qd2 It's not an option for White to accept the trade in this kind of structures, because Black has the bishop pair and a flexible pawn structure. White has to fight against the king which stucks in the middle.

13.Qxc5?! Rxc5 14.Bd3 e6 15.Rhf1 Rh5

13...f5 

14.e5 Seems to be a good practical move, but the line 14.exf5! Bxf5 15.Bb5+ is more promising for White.

14...e6? A decisive mistake!

14...Bg7! was the only playable move, 15.exd6 (15.Be2 Bc6 (Naiditsch,A (2641)-Heberla,B (2465) Warsaw rapid 2005) 16.Qd3 dxe5 17.Qxf5 e6 18.Qg4 0–0 and Black looks ok.) 15...Bxc3 16.bxc3 Qxc3 17.dxe7 Qxd2 18.Rxd2 Kxe7= with an approximately equal endgame.

15.g4! 

Nice start of a dangerous attack!

15...Bc6 15...fxg4 could have been met by 16.Ne4+– with a decisive attack!

16.Bg2 Bxg2 17.Qxg2 Rg8 In case of 17...Qc6 White wins after 18.Qe2 fxg4 19.exd6 Bxd6 20.f5+–

18.Qxb7 Rc7 19.Qa6 Rxg4?! Makes things easier for White. 19...Rc6 would have been more persistent, because now White has to find 20.Qa4! finden muss. (20.Qb7? Rxg4 21.Rhe1 d5) 20...Rxg4 (20...Qc4 21.Qxc4 Rxc4 22.gxf5+–) 21.Nb5! Qc4 22.b4!! A brilliant move to keep the pin on the a4–e8 diagonal. 22...Rxf4 23.Nd4!+– A nice tactical motif and White wins!

20.exd6 Rc6 21.d7+ Kd8

22.Qb7! White found the only winning move, however it was not so hard!

22...Bd6 23.Nb5! Rb6

23...Qxc2+ doesn't help, because of 24.Ka1+– and the white king is safe.

24.Nxd6! A great finish of a nice game!

24.Nxd6 Rxd6 (24...Rxb7 25.Nxb7++–) 25.Rxd6 Qxd6 26.Qc8+ Ke7 27.Qe8++– 1–0
