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.

White still has to prove his compensation after this} 23. Bc5 { Threatening mate on g7.} (23.

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.

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.
