King's Gambit
Monday, November 15, 2004
 
Lassila, T. - Laakkonen, T. (D16 - Slav Accepted)

1. d4 d5
2. c4 c6
3. Nc3 Nf6
4. Nf3 dxc4


Deferring the acceptance of the gambit leads to no better results than the standard QGA.

5. a4 Bd7?

Keeping the pawn but hindering the queen knight's development.

6. e4 b5
7. axb5 cxb5
8. e5 Ng8


8...Ng4 is met with the same response: 8...Ng4 9.Ng5 Qb6? (9...Nh6 10. Qf3 Nc6 11. e6! fxe6 12. Nxb5 +/-) 10.Qf3 Nh6? (10...Qxd4) 11.Qxa8 Bc6 12.Qxa7 1-0 (Jirovsky-Nadrchal, 1996).

9. Ng5 f6

Unsuccessful was 9...e6? 10.Qf3 f6 11.exf6 gxf6 12.Qh5+ Ke7 13.Qf7+ Kd6 14.Bf4+ Kc6 15.Nxe6 Bxe6 16.Qxe6+ Kb7 17.Be2 Nc6 18.Bf3 Qc8 19.Qf7+ Kb6 20.Nd5# 1-0 (Fehsenfeld-Drezewski, 2003). Black should try 9...Nh6 10. Qf3 Nc6 11. e6! fxe6 12. Nxb5 but things looks bleak.

The knight will not soon move from g5.

10. Qf3 Nc6?

10...Bc6 11. d5 fxg5 (11...Bb7? 12. Ne6 Qc8 13. Nxb5 +-) 12. dxc6 Qc7 +/-

Position after 10...Nc6

11. e6 Nxd4

A piece is going but this way Black will gain some material compensation. More serious is the king's position.

12. exd7+ Kxd7
13. Qe4 Nb3


Black tries to hang on to the game but now threats of mate start looming in the air.

14. Ra6! Qc8

After the forced 14...Qc8 three of White's pieces are hanging plus there's a fork threat on c5, but the threat of mate on c6 takes precedence. Black is irrecoverably lost.

15. Qd5+ Ke8

White also had the clever shot 15. Nxb5! and if 15...Qxa6? then 16. Qd5+ Kc8 17. Qxc4+ Kd8 18. Qc7+ Ke8 19. Nd6+! exd6 20. Qf7+ Kd8 21. Ne6+ Kc8 22. Qc7#.

16. Qxb5+ Qd7
17. Qxd7+ Kxd7
18. Nf7 Nxc1
19. Bxc4 Rc8


The knight on c1 is trapped.

20. Rxa7+ Ke8

20. Be6+ wins also. After 20. Rxa7+, 20...Kc6 21. O-O Kb6 22. Ra4 and Black can resign.

21. Be6 Rb8

Now it's mate in 4 beginning with a problem-like move.

Position after 21...Rb8

22. Nb5! 1-0

22...Nd3+ 23. Kd2 Rc8 24. Ra8 Rxa8 25. Nc7#
