FROM CHESS TODAY - 2931 (16th November 2008)

Van Wely,Loek (2618) - Radjabov,Teimour (2752) E97

38th Olympiad Dresden GER (3.5), 15.11.2008

Mikhail Golubev (www.chesstoday.net)
The first 23 moves of this game between leaders of the Dutch and Azerbaijani teams were known to me, but while looking at the rest of the game I did not understand much.

1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0-0 6.Be2 e5 7.0-0 Nc6 8.d5 Ne7 9.b4 Nh5 10.g3

From 2005-2007 there were four (!) Van Wely vs Radjabov games in the variation 10.Re1 f5 11.Ng5 Nf6 12.f3 Kh8 13.Ne6 Bxe6 14.dxe6. Now Van Wely returns to 10.g3, the old line, which he has played often in the past.

10...f5 11.Ng5 Nf6 12.f3 f4!? 13.b5

There are other options, for example 13.Kg2 which Van Wely preferred in the 1990s.


After 13...fxg3 14.hxg3 Nh5, the novelty 15.Kf2!? N was introduced in Van Wely-Dyachkov, Russian ChT Dagomys 2008 (1-0, 26). Instead, 14...h6 should transpose to our main game. In several games Black tried 13...Ne8 14.Ne6 Bxe6 15.dxe6 Qc8 16.Nd5 Qxe6 17.Nxe7+ Qxe7 18.Qd5+ Kh8 19.Qxb7 Nf6.

14.Ne6 Bxe6 15.dxe6 fxg3 16.hxg3 Qc8! 17.Nd5! Qxe6 18.Nxc7 Qh3 19.Rf2

Avoiding the draw 19.Nxa8 Qxg3+ = as in Pacmann-Taimanov, Havana Capablanca mem 1967 and other games.


Instead, 19...Rac8 20.Rh2! Qxg3+ (20...Qd7 21.Nd5 Nexd5 22.cxd5 Nh5 23.Kg2! +/= followed by Be3) 21.Rg2 Qh3 (21...Qh4? 22.Ne6 Rf7 D.Hamilton-Marcinkiewicz, ICCF corr. 1988 23.Rh2! Qg3+ 24.Kh1 Nh5 25.Be3 +/- Van Wely, Informator 79) 22.Qxd6! Rf7 23.c5 was Van Wely-Golubev, Romanian ChT Sovata 2000. Relatively best here is 23...Nf5! 24.exf5 Rfxc7 but now I see that perhaps White is better after 25.Be3! Qxf5 26.Rf1!?. 19...Rad8 20.Rg2 Qd7 21.Nd5 Nexd5 22.cxd5 Qc7 23.Be3 +/= is one of lines from my book 'Understanding the King's Indian' where I discussed this line. (See CT-1972 for more).

20.fxe4 N

A novelty, which has already been discussed in several publications. Black had a fully playable position after 20.Rh2 Qd7 21.Nxa8 Nxg3! 22.Bxh6 Bxh6 23.Rxh6 Kg7 24.Rh2 Nef5! in Van Wely-Degraeve, Mondariz Zonal 2000.

20...Rxf2 21.Kxf2 Rf8+ 22.Ke3!

22.Ke1 gives Black an additional possibility of 22...Qh1+!? 23.Kd2 Qxe4 and now 24.Qg1 (Shipov, KasparovChess.com, 2000), is quite complex.

22...Qxg3+ 23.Kd2

A crazy line, indeed. Black's minor pieces are relatively passive, which gives hope for White to consolidate his advantages.


After 23...Nf5?! 24.exf5 e4 25.Qb3! (Shipov) 25...Qxb3 26.axb3 Bxa1 27.fxg6 Black has problems in the endgame.


Not dangerous for Black is 24.Qb3?! Qg2 25.Qd3 (or 25.Qe3 h5! Gallagher, 'Play the King's Indian') 25...Nf5! (even stronger than Van Wely's suggestion 25...h5 with the idea of 26.Bb2?! Bh6+ 27.Kd1 h4 -/+) 26.exf5 e4 - Gallagher.


The first really new move. Van Wely himself provided the following line in Informator 79: 24...g5 25.Qb3 Qg2 26.Qe3 Ng6 27.Ba3 (a possible improvement is 27.Bb2, or maybe to take on g7 earlier - MG) 27...Nf4 28.Re1 g4 29.Nxg7 Rf3 30.Qxa7 Rd3+ 31.Kc2 Qxe4 32.Bxd3 Qxd3+ 33.Kb2 Qd2+ 34.Kb3 Qxe1 35.Ne8 Qb1+ = . Here Loek stops, but the line can be continued with 36.Ka4 Qc2+ 37.Ka5 Qxa2 38.Qe3 Qxc4 39.Nxd6, is not White somewhat better here?


Not 25.Nxd6?? Bh6+ 26.Kc2 Bxc1 27.Rxc1 Qe3 -/+.

25...Kxg7 26.Qb3 Qg2 27.Qe3 Ng8! 28.c5! dxc5

After 28...Nf6?! White plays 29.cxd6! Nxe4+ 30.Kd3 +/- with a big advantage: 30...Rf6 (or 30...Nxd6?! 31.Qxe5+ Kf7 32.Qxd6 Rxe2 33.Qf4+, developing the bishop then) 31.Bb2 Rxd6+ 32.Kc4 Kh7 33.Rg1 Nd2+ 34.Kb4 and so on.

29.Bb2 Qh2?!

Possibly critical is 29...Nf6! 30.Re1! (not 30.Bxe5? Rxe2+ 31.Qxe2 Qg5+ -/+) and now 30...Ng4!? (rather than 30...Nxe4+ 31.Kd3!? c4+ 32.Kxc4) 31.Qd3 deserves serious investigation.

30.Re1 Nf6 31.Kd1 b6?!

A much better chance was 31...Ng4 32.Qxc5 Qf4 33.Qe7+ (33.Qc7+ Kf6! 34.Qd6+ Kg7 35.Qd7+ transposes) 33...Kh8 34.Qd8+ Kg7 35.Qd7+ Kh6!? (35...Kh8? 36.Qc8+; 35...Kf6 36.Bc3! is complex, but better for White) 36.Bc1 Ne3+ 37.Bxe3 Qxe3 and here, at least, not dangerous for Black is 38.Bxh5?! (there are several alternatives: 38.Qd2!?; 38.Qd8!?; 38.Qd5!?) because of 38...Qc3! 39.Be2 Qa1+ 40.Kd2 Qb2+ 41.Ke3 Rh2 42.Qd3 Qxa2 =.

32.Bc3 +/- 32...Kh7

It is already hard to suggest anything for Black: 32...Qf4 33.Qxf4 Rxf4 34.Bxe5 Rxe4 35.Bf3!? Rxe1+ 36.Kxe1, winning the a7 pawn soon; or 32...Ng4? 33.Bxg4 hxg4 34.Bxe5+ Qxe5 35.Qxf2.

33.Qg5 Nxe4

After 33...Qg2 34.Qxg2 Rxg2 35.Bxe5 Nxe4 Black should not survive: 36.Bf3!? Rd2+ 37.Kc1 Ng5 38.Bf4 Rf2 39.Bxg5 Rxf3 40.Re7+ Kg8 41.Rxa7, etc.

34.Qe7+! Kh6 35.Bxe5! Rf7 36.Qe8!

Stronger than 36.Qxf7 Qxe5 37.Bd3 +/-.


A slight practical chance was 36...Rf4!?.

37.Kc2! +-

But not 37.Qxd7? Qxe5 and Black is doing well.

37...Rd2+ 38.Kb1!

Not 38.Kc1? Qf2 39.Rf1 Rc2+ 40.Kb1 Nd2+ 41.Kxc2 Nxf1 and the fight continues.

38...Qf2 39.Rf1! Rxe2

If 39...Qxe2? 40.Qf8+ Kg5 41.Qf4#.


This does not spoil the win, but 40.Rxf2 was simpler, indeed, as there is no mate after 40...Nc3+ 41.Ka1 Rxa2+ 42.Rxa2.

40...Kg5 41.Rxf2 Rxf2

The rest is not especially interesting.

42.Bb8 Rf5 43.Bxa7 c4 44.Bxb6 Rxb5+ 45.Kc2 Rxb6 46.Qe5+ Kh6 47.Qxe4 g5 48.a4 Rf6 49.a5 g4 50.Kc3 Kg5 51.Qe5+ Kg6 52.Qe4+ Kg5 53.Qb7 g3 54.a6 1-0
