[Event "USCF Rated Game"] [White "DashCancel"] [Black "NN"] [Result "1-0"] [ECO "C21"] [WhiteElo "1580"] [BlackElo "1550"] [PlyCount "65"] {C21: Danish Gambit} 1. e4 e5 2. d4 exd4 3. c3 dxc3 4. Bc4 cxb2 {The Danish Gambit is an important gambit line in the Open Game (1.e4 e5). White offers two pawns immediately in return for complete central domination with his bishops. If Black chooses to accept one or both pawns, he must play carefully, as Black's kingside becomes extremely vulnerable after seemingly normal development moves.} (4... d5 $11 {is an important variation that gives Black immediate equality.}) 5. Bxb2 Bb4+ (5... d5 {Is the main line, returning the pawns immedately and trading off queens in order to diffuse White's initiative. } 6. Bxd5 Nf6 7. Bxf7+ Kxf7 8. Qxd8 Bb4+ 9. Qd2 Bxd2+ 10. Nxd2 Re8 11. Ngf3 Nc6 12. O-O) 6. Nc3 $5 {Kf1 and Nd2 are more common. Having previously played Kf1, I find that it's hard to complete development if Black plays accurately.} Nc6 7. Nge2 $5 {More accurate is Nf3, but I like the idea of keeping f2-f4 as an option.} Nf6 8. O-O d6 $5 $11 {A strategic inaccuracy; Black should aim to play d7-d5 in one move. At this point, Black is two pawns up, but White's initiative keeps the position equal. White will attempt to mount an overwhelming kingside attack, while Black aims to safely complete development and trade down to an endgame with a winning advantage.} (8... Bd6 {is a favorite of Houdini, but would be difficult to find over the board.} 9. Nb5 Be5 10. Bxe5 Nxe5 11. Rc1 $15) 9. Qb3 {Nd5 right away is just a tiny bit better as it complicates matters more for Black.} (9. Nd5 $1 Bc5 (9... Nxe4 $2 10. Nxb4 Nxb4 11. Ng3 $1 d5 12. Qa4+ Nc6 13. Bxg7 $1) 10. Nxf6+ gxf6 11. Rc1 Ne5 12. Nf4 c6 $11) 9... O-O 10. Nd5 $1 {Threatening the bishop on b4 and ultimately disrupting Black's kingside pawn structure.} Bc5 {objectively the best move Black has.} (10... Nxe4 $4 11. Nxb4 {Despite having 3 pawns for the piece, White's initiative and domination of the entire board secures the advantage.} Na5 (11... Nd2 $4 12. Qg3 $1 $18) 12. Qc2 Nxc4 13. Qxc4 Re8 $16 (13... Nd2 $4 14. Qc3 {Threatening mate on g7} Qg5 15. Bc1 $1 {Pinning and winning the knight } c5 16. Nc2 $18)) 11. Nxf6+ gxf6 12. Qg3+ {This queen transfer to the kingside allows White to exploit the weak pawn in Black's position immediately. } Kh8 13. Qh4 {There's now the immediate threat of 14. Bxf6, winning Black's queen.} Ne5 {Forced.} 14. Kh1 $1 {The bishop on c4 is taboo as the Black knight is the only piece preventing Bxf6.} Be6 {Black would love for White to cede the bishop pair and fix his weak pawn structure, but White has a great resource to prevent this.} 15. Bd3 $1 {Again playing on the x-ray on f6. White now has ideas of f2-f4 and e4-e5, exploiting the weak h7 pawn.} (15. Bxe6 $2 { A strategic mistake, as Black's weakness can now be dissolved.} fxe6 $15 {The pawn on f6 is now defended by the rook, killing White's attack.}) 15... Rg8 16. h3 {A quiet but necessary move, preventing Rg4.} Kg7 $5 {An interesting attempt to bring the Black king to safety. Houdini doesn't take much issue with it, but it certainly looks ugly.} (16... Rg6 $1 {An exchange sacrifice is another way that Black can stay in the game.} 17. Nf4 Kg8 18. Nxg6 fxg6 $11) 17. Nf4 Nxd3 $4 {Black misses a critical tactic that allows White to exploit the weak f6 pawn.} (17... h6 $142 $11 {keeps the position equal.}) 18. Bxf6+ $1 $18 Qxf6 19. Nh5+ Kf8 20. Nxf6 {White wins a queen and a pawn for two minor pieces, giving him a winning game.} Rg6 21. Nd5 (21. f4 $142 {is objectively better, but there's no need to take risks with such a clear advantage.} Nf2+ 22. Rxf2 Bxf2 23. Nxh7+ Kg8 24. Qxf2 Kxh7 25. f5 $18) 21... Bxd5 22. exd5 Kg7 23. Rad1 {Removing the pesky threats on f2.} Ne5 24. f4 Ng4 $2 {Black is hoping for 25. hxg4?? Rh6!} 25. f5 $1 Bf2 {Desperation.} 26. Rxf2 Nxf2+ 27. Qxf2 Rf6 28. Rc1 c5 29. dxc6 bxc6 30. Rxc6 d5 31.
