Seis perfectos en Reikiavik

13/03/2015 – Esos son los que quedan con pleno en el marcador tras 4 rondas. El grupo lo comanda Mamedyarov, pero Eljanov no marcha muy por detrás. Gran cantidad de jugadores se mueven en medio punto, así que veremos enconadas luchas por mantener el ritmo de los líderes. Los análisis y las fotografías corren a cargo de Sagar Shah y Alina l'Ami respectivamente...

¡Vaya diferencia con la ronda 3! La mayoría de los jugadores con blancas ganaron en la ronda previa, pero en la 4 parecía que la suerte era negra. En realidad, la mayor parte de los jugadores con más Elo llevaban las piezas de ese color, pero no se esperaba un grado tal de partidas decantadas hacia ese bando.

En el primer tablero, el el joven y talentoso noruego Aryan Tari no pudo aguantar al super GM Pavel Eljanov.

Pavel Eljanov logró una enrevesada victoria en la ronda 4 contra Aryan Tari

[Event "Reykjavik Open 2015"] [Site "Reykjavik ISL"] [Date "2015.03.12"] [Round "4.1"] [White "Tari, Aryan"] [Black "Eljanov, Pavel"] [Result "0-1"] [ECO "B48"] [WhiteElo "2509"] [BlackElo "2727"] [Annotator "Sagar Shah"] [PlyCount "58"] [EventDate "2015.03.10"] 1. e4 c5 2.

This is quite a new and fashionable line. It may not replace the main line with 7.Qd2 but it is definitely a worthy alternative.} Bd6 { Eljanov goes for a relative side line. Just six games have been played with this move and almost all of them in 2014-15.} (7... Ne5 8.

Eljanov definitely seemed like the better prepared player but Aryan Tari had his chances which he failed to take advantage of.} 0-1

La racha de Zhansaya Abdumalik la frenó Hjorvar Gretarsson, que es el islandés con mejor marcador (4.0/4)

Zhansaya Abdumalik no pudo continuar su racha

She beat GM Henrik Danielsen in round three but in round four she was unable to keep the momentum and lost to Gretarsson in a very interesting game.} 1. e4 e5 2. Nf3 Nc6 3. Bb5 Nge7 4. c3 (4. O-O {is more popular than 4. c3 that was played in the game.}) 4... d5 {A very interesting variation which allows White to take the pawn on e5.} 5.

Bc4 Nd5 {By the looks of it things look pretty good for White. Black pawn structure is completely ruined. While seeing static features is easier, the dynamic ones are a tad difficult to spot. Look at the black bishops. They have excellent open diagonals to work with while the white bishop on c1 is sort of locked in. All in all Black is doing excellently in this position.} 8. Qe2 Be6 $1 9. Qxe4 Bd6 $1 {White wins a pawn but Black keeps developing.} 10. Bxd5 $2 { What was the need to give up the bishop?} (10. d4 $1 O-O 11. Bd3 (11. O-O $6 Nxc3 $1 12. Qxc6 (12. bxc3 Bxc4 $15) 12...

También con ese marcador está el ajedrecista polaco Jacek Stopa:

[Event "Reykjavik Open 2015"] [Site "Reykjavik ISL"] [Date "2015.03.12"] [Round "4.5"] [White "Christiansen, Johan-Sebastian"] [Black "Stopa, Jacek"] [Result "0-1"] [ECO "A13"] [WhiteElo "2351"] [BlackElo "2544"] [Annotator "Sagar Shah"] [SetUp "1"] [FEN "r1b2rk1/pp1nq1pp/2pbpn2/3p1p2/2P5/1PNPP1P1/PB2NPBP/R2Q1RK1 b - - 0 10"] [PlyCount "23"] [EventDate "2015.03.10"] {I would like to show you this game in order to learn the art of bringing your pieces to good squares. Have a look at this position and the posting of the black pieces. The knight on d7 is blocking the bishop on c8 and it all looks pretty cramped for black just like a normal Stonewall position. But now Jacek Stopa tries to unwind his pieces one by one.} 10... Ne5 $1 {The knight jumps to a square on the middle of the board from where it can easily be kicked. The idea is to go back to f7 and free the d7 square for the development of the bishop.} 11. Qd2 Nf7 {On f7 the knight stands well and can always come to g5 to pressurise the White kingside.} 12. Rad1 Bb4 $5 {When White played Rad1, a3 became impossible. Black uses this opportunity to establish an irritating pin.} 13. Nd4 Bd7 {Just developing. The bishop looks bad at the moment but glory awaits him on the square h5.} (13... e5 14. Nc2 $14) 14. Qe2 (14. Nc2 {was a better move forcing the bishop to move back.} Bd6 $13) 14... dxc4 $1 {A very nice move to change the structure and get the central pawns rolling.} 15. bxc4 e5 16. Nf3 e4 17. Nd4 Rad8 {Bringing the last piece into the game.} 18. Nc2 Bd6 19. d4 Be8 $1 {Still maximally trying to improve the positioning of the pieces. } 20. Ne1 Ng5 $1 {The knight as promised jumps to g5 probing the light squares and making way for the bishop.} 21. f3 Bh5 $1 $17 {Look at how beautifully black has activated each and every piece in his position. The important maxim to follow is always try to improve your worst placed piece and find good squares for it to be developed on. Black went on to win the game easily in 46 moves.} 0-1

Por último tenemos un ejemplo de algo que nos ha pasado a todos: perder una posición ganada. Sagar Shah explica el efecto psicológico que eso tiene en los jugadores.

[Event "Reykjavik Open 2015"] [Site "Reykjavik ISL"] [Date "2015.03.12"] [Round "4.22"] [White "Colovic, Aleksandar"] [Black "Poley, Vladimir"] [Result "1-0"] [ECO "B06"] [WhiteElo "2482"] [BlackElo "2269"] [Annotator "Sagar Shah"] [SetUp "1"] [FEN "6R1/8/8/8/1p2kp2/1r6/3K2P1/8 w - - 0 62"] [PlyCount "15"] [EventDate "2015.03.10"] {The sequence of moves shows a very common phenomenon that happens in chess. The lower rated player gets a winning position against his much higher rated opponent but is then met with stiff resistance in converting his advantage. Instead of playing objectively, the lower rated player in his bid to win often goes for lines without calculation, just out of intertia. The result can be highly dangerous. Here, Poley Vladimir, the player with the black pieces has played well upto this point to get a pawn up position against his much higher rated opponent. The problem now is that he is unable to find a win. What happens next is heartbreaking.} 62. Re8+ Kf5 63. Rf8+ Kg4 64. Rg8+ Kh4 65. Rh8+ {I would say that it is impossible to win this position because the Black king cannot escape the checks. But Poley doesn't want a promising position to be drawn and blunders a rook.} Kg3 $4 66. Rh3+ Kxg2 67. Rxb3 f3 68. Ke3 f2 69. Rb2 {A highly unfortunate result but something that we all can learn from.} 1-0
