N.N. - Lassila,T. (E32 - Nimzo-Indian, Classical)

1.d4 Nf6
2.c4 e6
3.Nc3 Bb4
4.Qc2 O-O
5.a3 Bxc3+
6.Qxc3 b6
7.Bg5 Bb7
8.e3 d6
9.Nf3 Nbd7

More usual is 9.f3. Now Black gets some pressure on the f3-square.

10.Bd3 h6
11.Bh4 c5

Also possible was 11...e5 12. Bf5 (12. dxe5 Nxe5 13. Nxe5 dxe5 14. O-O +/=) exd4 13. Qxd4 Bxf3 14. gxf3 Ne5 15. Qf4 +/=.

12.O-O Rc8

Interesting is 12. b4 cxd4 13. exd4 e5 14. dxe5 dxe5 15. Bf5.

13.Nd2 cxd4
14.exd4 d5

Using the pin to give White an IQP.

15.Qb4 e5

This is going too far. 15...dxc4 16. Nxc4 Ba6 17. Rfd1 Nd5 18. Bxd8 Nxb4 19. axb4 Bxc4 20. Bxc4 Rxc4 was better.

16.Bf5 exd4?

It was still possible to play 16...Rc7 17. cxd5 Bxd5 18. dxe5 Nxe5 +/=. Now White has good winning chances.

Position after 16...exd4

17.Bxf6! Nxf6

Black will avoid mate after 17...gxf6 18. Qb3 Rc7 19. Qg3+ Kh8 20. Qh4 Kg7 21. Qg4+ Kh8 22. Qxd4 Ne5 23. Qf4 Kg7 24. Qg3+ Ng6 25. cxd5, but will have a miserable position. I considered it better to give the exchange and try to gain counterplay in the center.

18.Bxc8 Qxc8
19.Rfc1 dxc4
20.Rxc4 Qg4

When down material, attack!

21.f3 Qe6
22.Rxd4 Nd5

The white queen is low on squares and the white rooks are uncoordinated.

Position after 22...Nd5

23.Qa4 Qe3+
24.Kh1 Bc6?

A critical position. Almost every piece is hanging at some point. It turns out that with 24...b5! 25. Qxa7 Nf4 26. Ra4! (26. Ne4 Bxe4 27. fxe4 Qf2 28. Rg1 Nh3 29. gxh3 Qf3+ 30. Rg2 Qf1+ =) 26...Qxd2 27. Rxf4 Qxf4 28. Qxb7 Black could still have good chances to draw. The remainder of the game is a cleanup operation despite the wild tactics that follow.

25.Qc4 b5

One move too late.

26.Qc5 Re8

Or Nf4 27. Rc4 Qxd2 28. Rc2 Qd5 29. Qxc6 Qxc6 30. Rxc6 +-. The rest is a pure attempt to swindle.

27.Qxc6 Qe1+
28.Nf1 1-0

How is one to defeat an opponent who refuses the offer of a free queen?

N.N. - Lassila,T. (B33 - Sicilian, Sveshnikov)

1.e4 c5
2.Nf3 Nc6
3.d4 cxd4
4.Nxd4 Nf6
5.Nc3 e5
6.Ndb5 d6

The Sveshnikov is my current main defense against king's pawn openings. It has a deserved reputation for being theory intensive, but this is acceptable in correspondence games. It also has the quality of allowing Black to play for a win, albeit not without taking some risks. Still, playing for the win from the start is a refreshing change to all those openings where Black simply aims for equality. As any Sveshnikov player can tell you, the key move in playing for a win is the early push f7-f5. Here we enter a sideline early on.

7.Nd5 Nxd5
8.exd5 Nb8

In my opinion this retreat is stronger than the option 8...Ne7. For one, it avoids the well-known trap 8...Ne7 9. c4 a6? 10. Qa4! +-. If now 9. c4 a6 10. Qa4, then simply 9...Nd7 and White had only some advantage in Westerinen-Kramnik, Gausdal 1992: 11.c5 Rb8 (11...dxc5!? 12. d6 axb5 13. Qxa8 would be riskier) 12.Nxd6+ Bxd6 13.cxd6 0-0 14.Be3 Nf6 15.Ba7 Ra8 16.Bc5 b6 17.Ba3 Bb7 18.Rd1 b5 19.Qb3 Qb6 20.Be2 Bxd5 21.Qe3 Qb7 22.Bc5 Nd7 23.b4 f5 24.f3 Bxa2 25.0-0 Be6 26.f4 e4 27.Bd4 Rac8 28.Qg3 Nf6 29.Rd2 Rc6 30.Be5 Qf7 31.Rfd1 Rd8 32.Ra1 Rdc8 33.h3 Nd7 34.Bb2 Bc4 35.Bh5 Qf8 36.Re1 Nf6 37.d7 Rd8 38.Be8 Qxb4 39.Red1 Qe7 40.Be5 Bd3 41.Qg5 Re6 42.Qxf5 Nxe8 43.dxe8=Q+ Rxe8 44.Rc1 Qf7 45.Qg4 a5 46.Bb2 Rg6 47.Qh4 Qd5 48.Rc7 h6 49.g4 e3 50.Rg2 e2 51.Bc3 Qd6 52.Be5 Qxc7 53.Rxe2 Qc5+ 54.Rf2 Rge6 55.Qg3 Qc1+ 56.Kh2 Be4 0-1

9.Qf3 a6

This is a sideline that's not often seen. White usually continues 10.Qa3 and tries to work over the d-pawn, but I don't really see the point of this when a straightforward king attack is building up after 10.Nc3. I can't believe it's a novelty, but could not find any games where this obvious retreat had been played.

10.Nc3! Be7
11.Bd3 O-O

Castling into it? Certainly, but here we observe one of the basics of counterplay in the Sveshnikov. Due to the center pawns being locked, Black can play f7-f5 quite freely and use the d7 square to re-route his pieces into play on the kingside. What looks like a strong attack for White will quickly turn into an attack by Black should the operator of the white pieces not beware. I opted not to delay castling in favor of 11...Nd7 due to 12.Qg3 O-O 13.Bh6 Bf6 14.Ne4, when for example 14...Kh8 15. Nxf6 gxh6 16. Nxh7 Rg8 17. Qh3 is most unpleasant. But it turns out both 16...Re8! with idea 17...e4 as well as 14...Nc5 stymie the attack with good counterplay.

12.Qh5 g6

Or directly 12...f5. I was planning to play it on the next move in any case.

13.Qh6 f5

Position after 13...f5

14.g4!? f4

Better is 14...e4, when 15. gxf5 Bxf5 16. Bxe4 Bf6 gives Black a comfortable edge. White now has a perpetual should he want it, but not much more. I took a gamble and figured my opponent would rather press on with his "attack" than take the draw, which allowed me to gain some advantage.

15.f3 Bh4+

Foregoing the aforementioned line 15. Bxg6 hxg6 16. Qxg6+ =. Now the black bishops activate and start to control the kingside. The next point on the agenda is to drive away the white queen.

16.Ke2 Bg5

Or 16...Nd7 17. Bxg6 hxg6 18. Qxg6+ Kh8 19. Qh6+ Kg8 20. g5 Qxg5 21. Qxg5+ Bxg5 22. Rg1 Kf7 23. Rxg5 Rh8 =.

17.Qh3 Nd7
18.Ne4 Be7

18...Nc5 19. Nxc5 dxc5 20. c4 would leave the e-pawn weak.

19.b4 Nf6

Here I did consider 19...Nb6 20. c4 Qc7 21. Nd2, but decided the kingside was where the action should be.

20.Ng5 Kg7

Black is not impressed by 21. Ne6+ Bxe6 22. dxe6, since after 22...Nd5 he stands OK.

21.c4 h6

Again 22. Ne6+ Bxe6 23. dxe6 Nh7 would be good for Black.

22.Ne4 Nxg4!?

This sacrifice is probably not required to obtain an edge and is most likely objectively refutable. However, stopping the mass of pawns and a powerful pair of bishops is not much fun and in retrospect this move was correct in the sense that it caused my opponent so much trouble that he later succumbed under the pressure.

Position after 22...Nxg4

23.fxg4 h5
24.Nf2 Bh4

No good is 24...Qb6 25. Rb1 Qd4 (25...f3+ 26. Kf1 Qd4 27.Rg1 +-) 26. Bb2! hxg4 27.Bxd4 gxh3 28. Bb6 +/-.

25.Ba3? Bxf2?

A blunderful moment in the game. Immediately winning was 25...f3+ 26.Ke1 e4. White had to play 25. Qf3, when after 25...Bxf2 26. Qxf2 Bxg4+
27. Kf1 Bf5 28. Bxf5 Rxf5 29. Bd2 the position is unclear at best.

26.Kxf2 hxg4

Better is 26...Bxg4 27. Qg2 Qh4+ 28. Kg1 Bf5 29. Bxf5 Rxf5 -/+.

27.Qg2 Qh4+
28.Kg1 Bf5
29.Bxf5 gxf5

I did not recapture with the rook to improve my pawn structure. If White is to survive the pawns coming down the board, he must immediately play the break c4-c5.

30.c5 Rac8
31.Rc1 Rc7

White is ahead in material, but in a very difficult position. Perhaps he could have played 32. c6 f3 33. Qf2 Qe7 34. h3 with some counterplay.

Position after 31...Rc7

32.Rc4?? Qe1+

Winning on the spot.

33.Qf1 Qe3+
34.Qf2 Qxa3
35.c6 bxc6
36.Kg2 Qh3+
37.Kg1 Qe3
38.Qxe3 fxe3
39.Kf1 Rfc8 0-1
