Isla de Man: mate con alfil y caballo

por Sagar Shah
09/10/2016 – Sagar Shah nos muestra cómo los jugadores de más de 2700 puntos Elo tienen un fino olfato, el instinto atacante de Shirov, la perspicacia táctica de Naiditisch y por último y no por ello menos importante, cómo dar mate con alfil y caballo. Hou Yifan afrontó el reto y la Campeona del Mundo no tuvo problemas. Crónica de la ronda 8...

Reportaje de la ronda 8

Arkadij Naiditsch vs S.L. Narayanan

La posición ya era mala para las negras y Naiditsch encontró la forma más rápida de ganar. Juegan blancas.

Harika ha jugado excelentemente en este torneo. Incluso Vishy Anand ha tuiteado sobre el sólido juego de la chica de Andhra:

En la ronda 8, la Francesa de Harika no resultó ser suficiente para la potencia de ataque de Shirov. El letón ganó una fina partida de ataque:

[Event "chess.com IoM Masters"] [Site "Douglas ENG"] [Date "2016.10.08"] [Round "8.7"] [White "Shirov, Alexei"] [Black "Harika, Dronavalli"] [Result "1-0"] [ECO "C19"] [WhiteElo "2679"] [BlackElo "2528"] [Annotator "Sagar Shah"] [PlyCount "99"] [EventDate "2016.10.01"] {Shirov started the tournament with 4.0/4.

Nf3 {Shirov doesn't go for the sharpest lines beginning with Qg4.} Qa5 8. Bd2 Nbc6 9. a4 Bd7 10. Bb5 a6 11. Bd3 c4 12. Be2 { The queenside is now closed. White has a clear plan of attack on the kingside with f4-f5. Hence, Black will castle queenside. Yet White will have to go for f4-f5 because that is the only active plan he has in the position. Because White's king will be on that wing, the position will become quite sharp. But, it will take several moves as the position is closed and a tempo doesn't really matter.} h6 13. O-O O-O-O 14.

She advances her h-pawn, but after g4, the idea of f5 once again becomes possible.} 27. g4 f6 28. Rf1 g5 $6 29. f5 $1 {This is exactly what White needed.

Tras su excelente arranque con 5.0/6 Vidit también recibió elogios de Vishy:

Aprender a dar mate con alfil y caballo

Al fondo, la partida entre Elisabeth Paehtz y Hou Yifan in progress. A la derecha está Tania Sachdev. Tras 66 jugadas se alcanzó la siguiente posición:

¿Tendría confianza para dar mate al rival con el alfil y el caballo? Si la respuesta es no, debería ver el vídeo de la parte inferior, en el que se explican algunos de los aspectos más importantes del mate con alfil y caballo.

Si tiene una cuenta ChessBase Premium también puede ir a Fritz Online, configurar la posición y practicarla contra el ordenador. Es la mejor forma de aprender en unos finales tan complejos.

Ajedrez de altos vuelos

En las bartallas entre jugadores de más de 2750 puntos Elo, los protagonistas se huelen enseguida cuando las cosas pueden ir mal y rápidamente buscan un recurso que les asegure al menos medio punto. Además su preparación en aperturas es extraordinaria. Eso fue lo que pasó en la ronda 8 en los primeros tableros Eljanov - Caruana y Nakamura - So.

[Event "chess.com IoM Masters"] [Site "Douglas ENG"] [Date "2016.10.08"] [Round "8.1"] [White "Eljanov, Pavel"] [Black "Caruana, Fabiano"] [Result "1/2-1/2"] [ECO "D37"] [WhiteElo "2741"] [BlackElo "2813"] [Annotator "Sagar Shah"] [PlyCount "61"] [EventDate "2016.10.01"] {Elajnov was half a point ahead of the field before the start of the eighth round. He was up against Fabiano Caruana. The latter definitely would be looking for blood as a win would mean, sole first spot.} 1. d4 Nf6 2. Nf3 d5 3. c4 e6 4. Nc3 dxc4 {The Vienna variation is not seen very often at the top level, but it is provocative in nature and quite good when you are trying to play for a full point.} 5. e3 (5. e4 {is much more active, but with a half point lead Eljanov decides to keep it solid.}) 5... a6 6. a4 c5 7. Bxc4 { We have now transposed into the Queen's Gambit Accepted territory.} Nc6 8. O-O Be7 9. Qe2 {White needs to develop his pieces and hence this move seems completely logical. But because a6 and a4 have been added, Black can now win the pawn on d4. The point of a6 being added is that the b5 square is covered and moves like Nb5 or Bb5 will no longer be possible.} cxd4 10. Rd1 (10. exd4 Nxd4 11. Nxd4 Qxd4 {is fine for Black.}) 10... e5 11. exd4 exd4 12. Nxd4 Nxd4 13. Qe5 {This is all well known theory. White is going to win back his piece, but overall it seems highly unlikely that he can fight for an edge in this position.} Qd6 14. Qxd4 Qxd4 15. Rxd4 Bc5 16. Rd1 (16. Rd3 {was tried by Koneru against Ju Wenjun recently, but it doesn't change the evaluation of the position.}) 16... O-O 17. h3 Be6 (17... Bf5 {is met with the strong} 18. Bd5 $1 {when it is not so easy to defend the b7 pawn.}) 18. Bxe6 fxe6 {That's a common idea. The e6 pawn will not be very weak. Meanwhile it was important to get rid of the important c4 bishop.} 19. Kf1 Nd5 20. f3 Nxc3 21. bxc3 Rac8 22. Rb1 b6 23. Re1 Rc6 24. Re4 Rd8 25. Bf4 Kf7 26. Be5 Rd2 27. Rg4 g6 28. Ke1 Rd5 ( 28... Ra2 29. Rd1 Ke7 30. Rd2 $11) 29. Rf4+ Ke7 30. Re4 Bd6 31. Bd4 { Theoretically it was an excellent result for Caruana, but judging from the tournament situation it was just what Eljanov needed. He is now half point ahead with just one round to go!} 1/2-1/2

Nakamura tendría ganas de venganza contra So, pero fue incapaz de herirlo

[Event "chess.com IoM Masters"] [Site "Douglas ENG"] [Date "2016.10.08"] [Round "8.2"] [White "Nakamura, Hikaru"] [Black "So, Wesley"] [Result "1/2-1/2"] [ECO "D70"] [WhiteElo "2787"] [BlackElo "2794"] [Annotator "Sagar Shah"] [PlyCount "61"] [EventDate "2016.10.01"] {Battles between Nakamura and Wesley So are always interesting. In their last encounter Wesley won with the white pieces at the Sinquefield Cup. So Nakamura was surely angling for a revenge.} 1. d4 Nf6 2. c4 g6 3. f3 d5 4. cxd5 Nxd5 5. e4 Nb6 6. Nc3 Bg7 7. Be3 O-O 8. Qd2 Nc6 9. O-O-O {Theory has been growing in the f3 line of the Grunfeld. This opposite side castling position is quite sharp and not everything has been worked out here. Hence, there is quite some scope for experimentation and new ideas.} Qd6 10. Nb5 Qd7 11. Kb1 Rd8 12. d5 a6 13. Nc3 Qe8 14. Qc1 Na5 15. Bf4 (15. h4 {is the main line and has been already seen between Nakamura and So in their Ultimate Moves Blitz Challenge.}) 15... Rd7 16. Bh6 Bxh6 17. Qxh6 e6 {Black has to sooner or later break in the centre. } (17... c6 18. Qe3 Nbc4 19. Bxc4 Nxc4 20. Qc5 $14) 18. Nh3 {Threatening Ng5.} Qf8 19. Qxf8+ Kxf8 20. Nf4 exd5 21. Nfxd5 Nxd5 22. Rxd5 b5 {White hasn't found anything special out of the opening and this looks like heading towards a dull draw.} 23. Be2 c6 24. Rxd7 Bxd7 25. Rc1 Be6 26. Nd1 Rd8 27. Ne3 Rd2 28. Rc2 Rxc2 29. Nxc2 c5 30. b4 Nb7 31. a4 (31. a4 cxb4 32. Nxb4 a5 33. Nc6 bxa4 34. Bb5 Nd6 35. Bxa4 Bd7 $11 {will end in a draw.}) 1/2-1/2
