It is a rare occurence nowadays in GM games. } exf4 3. Nf3 d5 {This is the reason the King's Gambit is so rare nowadays. This line has been basically proven to be at least equal for Black.} 4. exd5 Nf6 5. Be2 Nxd5 6. c4 Ne7 (6... Nb4 {is also ambitious, for example:} 7. d4 Bf5 8. Na3 g5 $5 {With a very unclear, Rapportesque, position.}) 7. Nc3 Ng6 8. h4 ( 8. d4 $44 {would be too normal of a move for the Hungarian to play.}) 8... Be7 9. h5 Nh4 10. Nd5 $5 {This frisky move is actually dangerous if Black is not careful.} Nc6 (10... Bg5 $5 11. h6 $1 Nxf3+ 12. Bxf3 O-O $1 13. d4 $1 {With just a mess on the board.}) 11. d4 Nxg2+ 12. Kf1 Ne3+ 13. Nxe3 fxe3 {Black is up two pawns, and White's king is lacking a pawn shelter, but White's pieces are very active and his pawn center is strong. Also, he will capture on e3 soon, after which Black's king feels uncomfortable no matter where he goes.} 14. d5 Nb4 15. a3 (15. Bxe3 {was a different move, that would have changed the game dramatically. Black does not have the c5 square for his bishop yet, but his knight is still in the game for now:} Bf5 16.

Bg4 $6 {Because of the following sequence, this natural move might be dubious.} (17... h6 $5 {was one way of trying to solidify the kingside.} 18. Rg1 Kh8 19. Bd4 Bh3+ 20. Ke1 Bf6 $13) 18. h6 g6 19. Qc3 Bf6 (19... f6 {is ugly. } 20. b4 $44) 20. Bd4 {Black faces some problems now on the darksquares. He cannot afford to trade bishops because of the double attack.} Be7 21. c5 $5 { A move probably only Rapport can come up with. White takes c5 away from Black, but he loses a key tempo in the attack.} (21. Bh8 $2 f6 $17) (21. Re1 $44) (21. Bf2 Bf6 22. Bd4 $11) 21... Re8 $1 (21... Qxd5 22. Bh8 {loses, as Bc4 next move (after f6) will win the queen.}) 22. c6 {Black has a lot of weird options here. } (22. Bc4 $5) 22... Bf8 (22... b5 $1 {Defends everything for now as b5 cannot be taken. White still has to prove his compensation after this} 23. Bc5 { Threatening mate on g7.} (23. Bxb5 Qxd5 $19) 23... f6 $15) 23. cxb7 Rb8 { Suddenly, with g7 covered, Black is taking over the initiative. For now, however, there is a knight hanging...} 24. Bxa6 (24. Bc4 $5) 24... Qxd5 25.

Kf1 {White is down the exchange, but his passed pawn on b7 supported by the queen force a perpetual.} Qh1+ 31. Kf2 Qh4+ (31... Rxb7 32. Qe5 {is already extremely dangerous, if not losing.}) 32. Kf1 Qh1+ 33. Kf2 {A wild ride!} 1/2-1/2

Un grupo de matemáticos han empezado a estudiar como escoge Rapport las aperturas. A mitad del trabajo decidieron que predecir los números de la lotería era una tarea más fácil

¿Un Gambito de Rey? La última vez que se enfrentó a uno fue contra Nakamura en el clásico de Londres de 2011. Nakamura ganó.

Eljanov, Pavel 0-1 Navara, David
La dudosa apertura de Eljanov lo dejó en una situación precaria y Navara se avalanzó sobre él con sus piezas desde todos lados:

Ha caído al último puesto

[Event "48th Biel GM 2015"] [Site "Biel SUI"] [Date "2015.07.21"] [Round "2.2"] [White "Eljanov, Pavel"] [Black "Navara, David"] [Result "0-1"] [ECO "A49"] [WhiteElo "2723"] [BlackElo "2724"] [Annotator "Ramirez Alvarez,Alejandro"] [PlyCount "90"] [EventDate "2015.07.20"] 1. d4 Nf6 2. Nf3 g6 3. g3 Bg7 4. Bg2 d5 5. O-O c6 6. Bf4 O-O 7. Qc1 {Eljanov chooses some kind of strange set up against the c6 Grunfeld. He doesn't want to commit to c4 yet, and he might keep the option of playing a later Bh6, trading off bishops.} Bg4 8. Nbd2 Nh5 9. Bg5 (9. Be3 Nf6 $11 (9... Nd7 10. c4 { is also fine for Black if he wants to play on.})) 9... f6 10. Be3 e5 {Because of this move it is unclear if Bg5 f6 really favored White.} 11. h3 Be6 12. g4 $5 {Making the position double edged.} Nf4 13. Bxf4 exf4 {Black's pawn structure isn't very good, but it contains White's pawns and pieces. Black might be slightly better, as if any big pawn trades happen the bishops will be very powerful.} 14. Nb3 Qc7 15. Nc5 Bf7 16. b3 g5 17. c4 Nd7 18. Nd3 Rae8 19. Re1 h5 $1 {By now it is quite clear that Black's pressure is mounting.} 20. gxh5 dxc4 21. bxc4 Nb6 22. c5 Nd5 {Black improves his knight and will capture on h5 when he pleases.} 23. Qa3 Bxh5 24. Nb4 Nxb4 25. Qxb4 Re7 26. Rab1 Rfe8 { Navara only has to play natural moves to continue applying pressure. White's position is already very unpleasant.} 27. d5 {An interesting sacrifice in order to diffuse the bad situation for now. However, a pawn is still a pawn...} cxd5 28. Nd4 Qd7 29. Qb3 Kh8 $1 30. Qxd5 Qxd5 31. Bxd5 Rd7 {Black's counter sacrifice is well calculated. At the end of the trades c5 will be extremely weak.} 32. Bf3 Bxf3 33. Nxf3 Bf8 {The point. There is no good way to defend c5. } 34. c6 bxc6 35. Kf1 Kg7 36. Rec1 c5 37. Rc2 Kg6 38. Ne1 f5 {Black's pawn mass on the kingside and better rooks give him a nearly decisive advantage.} 39. Rbc1 g4 40. hxg4 fxg4 41. Rc4 Kg5 42. Ng2 Rh7 {Black is even threatening checkmate! Actually, this move is not very accurate.} (42... Rd4 $1 43. Rxd4 cxd4 $19) 43. Rxc5+ $6 {Trying to simplify the position, Eljanov falls for a nice trick.} (43. Kg1 $1 $17) 43... Bxc5 44. Rxc5+ Re5 $1 (44... Kf6 45. Nxf4 { would be still hard to break through.}) 45. Rxe5+ Kf6 {Because of the trade of rooks, The resulting position is winning elementary. White cannot hold the a-pawn for long.} 0-1

Una hermosa recuperación de Navara tras perder la primera partida

Vachier-Lagrave, Maxime ½-½ Wojtaszek, Radoslaw
Si alguien estuvo peleando por la ventaja en esta partida, probablemente fue el jugador polaco, pero eso no quiere decir que MVL corriese serio peligro en algún instante. Tras muchos cambios de piezas, el peón pasado de las negras era relativamente insignificante ya que el final de alfiles de colores opuestos daba a la partida mucha tendencia a las tablas.

El polaco aprentó un poquito
