New Directions in the Exchange Grunfeld - TWIC Theory #4

TWIC THEORY Tuesday 22nd March, 2005

NEW DIRECTIONS IN THE EXCHANGE GRUNFELD By IM Tibor Karolyi and IM Andrew Martin Tibor Karolyi is an International Master, and Trainer. Hello, I'm Tibor Karolyi. As a player my best result was to win the Hungarian Open championship in 1984. Between 1977 and 1986 I was a training partner of Zsuzsa Polgar. I started to train in 1989, my very first pupil was the 10 year-old Peter Leko. I estimate his level was 1900; he made 0 point out of 9 in a category III tournament. We stopped working together in October 1993; by that time he had 2 grandmaster norms and an Elo rating of 2555. Three months later, he broke the record for the youngest ever grandmaster. In 1998 we started to work together again, our work ended at end of 2000. In 1994 I trained Sofia Polgar for six months. She increased her Elo by 70 points. She took a silver medal at the world junior championship (under 20) for boys. Shortly after we stopped working together, she made 12.5 points out of 14 on board two at the Moscow Olympiad. My third GM pupil is Zoltan Gyimesi; his best result was the bronze medal at the world championship under 20. I trained Zoltan from 1991 to 2000; we started to train when he was 14. From 1997 to 2000, I trained women GM Ildiko Madl. She made decent scores when I prepared her for 4 world events. Her result included 6.5 out of 9 on board 1 at the Batumi European Championship. Monika Grabics won the Hungarian women's championship; she also made a 2540 performance beating several grandmasters, including Sax. My pupils have won 7 medals in world junior championships. Tejas Bakre from India won the Asian under 20. Jure Borisek (Slovenia) was 57th at world junior under 14 in 1999. After some intensive training with me, he made 3-6 place at the same tournament. I had many pupils who are international masters, the best of them the two times Hungarian champion Sandor Videki.

From 2002 April I have been working in Singapore. At the boy's world under 16 team championship Singapore finished 9th ahead of England and USA. When I started to train Jason Goh in 2002 he was 7th at the boy's under 14 South Asian championships; his Elo was 2070. One year later he finished 2nd at the rapid championship, knocking out 3 grandmasters on the way. He eliminated Zaw Win Lay, Adianto and in the semi-final, he beat grandmaster Wu Shaobin. He did this before his 14th birthday. He was leading the world under 14 championships in 2003, finishing 4-8th. In 2004 my book on Judit Polgar was published.

Kruppa,Yuri (2547) - Slizhevsky,Alexander (2407) [D85] Chigorin mem 12th St Petersburg (9), 24.10.2004 [notes by Andrew Martin] Greetings! We recently received a very interesting article by Tibor Karolyi and decided to combine it with an expanded version of a recent theoretical by Andrew Martin ... We think you'll agree that the subject matter is very interesting. Martin investigates Kruppa's 7 Bg5!?, a virtually unknown new idea, and then Karolyi describes the latest developments after 8 h3, a move used by Vladimir Kramnik against Gary Kasparov. 1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.cxd5 Nxd5 5.e4 Nxc3 6.bxc3 Bg7 7.Bg5!?

A new one on me. No Grunfeld textbook anywhere, anytime mentions this interesting idea of Yuri Kruppa, and so this week we will subject 7 Bg5 to as close an examination as we can muster. If White's centre doesn't fall apart it has to be said that g5 is a good square for the Bishop. Black's e pawn gets nailed down and there are the usual attacking opportunities based on Qd2, Bh6 h4-h5 etc. Slow play by Black will give White an excellent Exchange variation in an improved setting. Thus the critical line is obviously

7...c5! 8.Rc1!? And this is White's point. c8 hangs after a capture on d4. It's easy to see why this idea hasn't been considered before. The d4 square looks very compromised and a move such as ...Qd8-a5 will surely break the back of White's centre. Matters are not so clear, as you will see. 8...Qa5 I think this is what most Grunfeld players will do, whether surprised or not. It's just so logical to hit c3. Yet after the coming exchange White benefits in the ending by having his Bishop on g5. This may have prompted 8...h6!? in the most recent example I could find. Black jabs the Bishop back to e3 and it's a question of whether ...h7-h6 is weakening or not. 9.Be3 Qa5 10.Qd2 cxd4 11.cxd4 Qxd2+ 12.Bxd2!? (I'm not sure I understand why 12.Kxd2 0–0 13.Nf3 was rejected) 12...0–0 13.Nf3 Rd8 14.Bb5 (I prefer 14.Rc7 e6 15.Ba5!? (15.Be3 Nc6 16.e5 Rd7 17.Rxd7 Bxd7 18.Kd2 Nb4 19.a3 Nd5=) 15...b6 16.Bd2 Ba6 17.e5 (17.Be3 Bxf1 18.Rxf1 Na6 19.Rb7 Nb4 20.Kd2 Nc6=) 17...Bxf1 18.Rxf1 Na6 19.Rb7 Rdc8 20.Ke2 Rc2 (20...Rc7 21.Rxc7 Nxc7 22.Rc1 Nd5) 21.a4+/=) 14...e6 (14...Bg4 is interesting: 15.Rc7! (15.d5 e6 16.Bc4 exd5 17.Bxd5 Nc6 18.Bxc6 bxc6 19.Rxc6 Re8 compensation) 15...Bxf3 16.gxf3 a6 17.Bc4 Nc6 18.d5 Ne5 19.Be2+/=) 15.0–0 (15.Ne5!? Nd7 16.Ba5 Nb6 17.Rd1 Bxe5 18.dxe5 Rxd1+ 19.Kxd1 Bd7 20.Bd3 Na4+/= Kruppa /Komarov I'm not sure what to believe about that last variation.) 15...Nc6 16.Bxc6 bxc6 17.Rfd1 Ba6 18.Be3

draw. Kruppa-Ganguly Dubai 2004. Either 18...Be2 or 18...Rab8 are satisfactory for Black in this final position. Virgin ground.;

Meanwhile Kruppa and Komarov mention the crazy variation 8...cxd4 9.cxd4 Bxd4 (9...0–0 10.Nf3 Bg4 This time Black pretends he's playing a normal line and keeps his Queen on d8 to both hit d4 and give added firepower to his counterplay. 11.d5! And once again this seems to be the way to put the pressure on. 11...h6 (11...Bxf3 12.gxf3 Nd7 13.Qb3+/= is on the face of it OK for Black but long term I really trust in those White Bishops. 13...b6; 11...Nd7 12.Be2 Nb6 13.0–0+/= is a relatively simplistic way to handle the Black pieces and he has not equalized yet. White could play Qb3, Rfd1, h3; easy moves and hold at least a slight edge.) 12.Bf4 f5?!

Black wants to say that he is not afraid to duck a challenge but ...f7-f5 looks positionally poor. There's no going back, that's the problem. 13.Bc7! I'm sure Black missed this move. 13...Qd7 14.e5+/- Bxf3 15.Qxf3 Nc6 16.Qb3! (16.dxc6 Qxc7 17.Bc4+ Kh8 18.cxb7 Qxe5+ 19.Qe3 Qa5+ 20.Ke2 Rab8 21.Rb1 f4 unclear) 16...e6 (16...Nd4 17.Qc4 Rac8 18.e6 Qe8 19.Qb4!+/-) 17.Bd6 exd5 18.f4! White insists on dominating the centre. 18...Rfe8 19.Qxd5+ Kh8 20.Bc4 g5 21.g3 Ne7 22.Qb5 Nc6 23.0–0 gxf4 24.gxf4 Bf8 25.Rcd1 a6 26.Qb2 Bg7 27.Qf2 Rac8 28.Bd5 Ne7 29.Bf7 Red8 30.Bb3 Qe8 31.Rd3 Ng6 32.Rfd1 a5 33.Kh1 a4 34.Bd5 Kh7 35.Bxb7 Rc4 36.Rf3 a3 37.Bd5 Qa4 38.Bxc4 Qxd1+ 39.Qf1 Qa4 40.h3 Nh4 41.Rxa3 Qc2 42.Bd5 Rc8 43.Rd3 Qb2 44.Ba3 Qb5 45.Rd1 Qa4 46.Rc1 Rb8 47.Bd6 Rb2 48.Qc4 Qa5 49.Rd1 Rd2 50.Rxd2 Qxd2 51.Bc5 Ng6 52.e6 Nxf4 53.e7 Qe1+ 54.Bg1 1–0 Kruppa,Y-Danin,A/St Petersburg 2004) 10.Rxc8 Bxf2+ 11.Kxf2 Qxc8 12.Nf3+/-

assessing this position as clearly better for White. Black is unlikely to go in for this over the board but if he does I append some extra analysis now: 12...0–0 a) 12...h6 13.Bb5+ Nc6 14.Be3+/-; b) 12...Nc6 13.Bc4 0–0 (13...Qg4 14.Qb3! 0–0 15.Bh6 Qxe4 16.Bxf7+ Rxf7 17.Qxf7+ Kxf7 18.Ng5++-) 14.Bh6 Rd8 15.Qa1+-; 13.Qb3! Nc6 14.Bh6 Rd8 15.Qb2 f6 16.Bc4+ Kh8 17.Rc1 The dark squares are simply too weak. Perhaps this last variation is the best that Black has, but he would surely only stumble here rather than come voluntarily. 9.Qd2 cxd4 10.cxd4 Qxd2+ 11.Kxd2

The aforementioned ending. Grunfeld players will know that the King on d2 gives them attacking opportunities, but that if they don't get it exactly right White's central majority and pressure on the c file may well carry the day. Kruppa has added some interesting nuances to the usual ending scenario by putting the bishop on g5. 11...0–0 Either castles or 11...Nc6 but then 12.d5 Ne5 13.Rc7!

gives the Bishop on g5 a reason to be and subjects Black to uncomfortable pressure. White has a definite advantage here: 13...Nd7 14.Bb5 (14.Nf3!

is less committal at this stage and probably better: 14...h6 (14...Kd8 15.Bf4 Nf6 16.Ng5! Rf8 17.Rc4 h6 18.Nf3+/=) 15.Bf4 Kd8 16.Bd3 g5 17.Bg3+/-) 14...Kd8 15.d6 f6 16.Bf4 e5 (16...exd6 17.Bxd6 Bf8 18.Bg3 Ne5 19.Rc2

Whose position is the more disorganised? Seeing the extra Rook in play, I think I would prefer to be White.) 17.Be3 Bf8 18.Bxd7 Bxd7 19.Rxb7 Bxd6 20.Ne2 (20.Rb1! Bc6 21.f3 Ke7 22.Ne2 Rhd8=/+) 20...Bc6 21.Rg7 Bb4+ 22.Nc3 Bxe4 Now it is White who will have to scrape a draw 23.a3 Bf8 24.Rf7 Bxg2 25.Rg1 Bf3 26.Rxf6 Bb7 27.Rf7 Be7 28.Bg5 Re8 29.Rxh7 Bxg5+ 30.Rxg5 Re7 31.Rxe7 Kxe7 32.Rxg6 Bh1 33.Rg1 Bc6 34.Rg6 Bh1 35.Ra6 Rh8 36.Rxa7+ Kd6 37.Ra6+ Kd7 38.Na4 Rxh2 39.Nc5+ Kc7 40.Rf6 Rh3 41.a4 Ra3 42.Kc2 Bd5 43.Kb2 Rh3 44.a5 e4 45.a6 e3 46.fxe3 Rxe3 47.a7 Re8 48.Kc3 Ra8 49.Kd4 Bc6 50.Na6+ Kb7 51.Nc5+ Kc7 52.Na6+ Kb7 53.Nb4 Be8 54.Rh6 Rd8+ 55.Kc5 Kxa7 56.Nc6+ ½–½ Taborov,B-Troshohenko,P/Kiev 2004 12.Nf3

12.d5!

was mentioned in Informator 90 as an interesting alternative to the text. It is extremely logical to assist the Bishop on g5 in this way. I analyse further: 12...e6 a) 12...f5 13.exf5 (13.Bc4!? Kh8 14.Bxe7+/-) 13...Bxf5 14.Bxe7 Bh6+ 15.Kd1! Bxc1 16.Bxf8 Kxf8 17.Kxc1 Nd7 unclear; b) 12...Nd7 13.Nf3 Nf6 14.Bd3 h6 15.Bxf6! Bxf6 16.e5 Bg7 17.Rc7 Rd8 18.Be4 Be6 19.Rxe7 Bxd5 20.Bxd5 Rxd5+ 21.Ke3+/=; 13.Nf3 exd5 14.exd5 h6 (14...Bg4 15.Rc7! Bxf3 16.gxf3 f6 17.Bf4 Rd8 18.Bc4+/-) 15.Be7 Re8 16.Rc7 Nd7 17.d6 a6 18.Bc4+/- In each case White managed to use the more attacking position of his Bishop on g5 to gain the advantage. Or am I being optimistic? Instinct says yes but the computer no. The eternal dilemma of modern chess. 12...e6 13.Rc7 Nc6 14.d5 I guess this is similar, although ...Nc6 didn't help much. 14...exd5 15.exd5 Nb4 16.Bc4 b5 17.Bb3 Na6 18.Rcc1 Bf5 19.Rhe1+/-

White has a superior exchange variation on all counts. He holds the usual passed d pawn, the c6 square and his pieces are extremely active. Black faces a tough defence. 19...Rfc8 19...h6 20.Be7 Rfc8 21.d6 Bb2 22.Rxc8+ Rxc8 23.Rd1 Nc5 24.Bd5 Na4 gives counterplay and perhaps should have been preferred. 20.d6 Bf8 21.Be7 Rxc1 22.Rxc1 Bxe7 23.dxe7 Re8 24.Rc6! Nb8 25.Rc7 Kg7 25...Nd7 26.Nd4! Rxe7 27.Rxa7 Kf8 28.Nxf5 gxf5 29.Rb7+26.Ne5 Nd7 27.f4 27.Nc6 a5 28.Ke3! a4 29.Bd5 Nf6 30.Kd4+27...Nxe5 28.fxe5 Be4 29.g4 f6 30.Ke3 Bg2 31.exf6+ Kxf6 32.g5+ Kg7 33.Rxa7 Bh1 34.Kf4 Bf3 35.Ke5 Bg2 36.Kd6 A rather triumphant King march. 36...Bh3 37.Bd5 1–0 New ideas don't crop up every day of the chess year, so if you are looking for something against the Grunfeld I think it's well worth taking a closer look at 7 Bg5!? It will certainly set your opponent thinking.

Beliavsky,A (2665) - Mikhalchishin,A (2515) [D85] 15th Vidmar mem, Terme Zrece Slovenia (5), 2003 [notes by Andrew Martin] It would be inappropriate to leave this subject without mentioning 6...c5, which I believe to be a very reasonable alternative course. 7 Bg5 would now be far too risky with Black's Queen already primed to enter the game and the Bishop on f8 could well land a nasty check on b4 too! So I'm recommending 7 Bb5+ now, a move that makes perfect sense. Black can't block any more with...c7-c6 and faces a difficult choice. The main problem is that Black is shunted into a position he can't really win if White plays even half-sensibly. 1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.cxd5 Nxd5 5.e4 Nxc3 6.bxc3 c5 7.Bb5+! Nc6

7...Nd7

is rather passive. In his book on the Grunfeld, Nigel Davies thinks that this is the best way for Black to play for a win but I just don't see it. Using the simplest methods, White obtains a nice centre with the Knight on d7 misplaced and Black's queenside difficult to develop. 8.a4! Bg7 9.Nf3 a6 (9...0–0 10.0–0+/=) 10.Be2 cxd4 11.cxd4 0–0 12.0–0+/=

White answers ...Nf6 with Qd3 and has Ba3 in the offing.; 7...Bd7 8.Be2! Bg7 9.Nf3 0–0

is again rather prospectless for Black. One might think this is just a normal Exchange Variation but I remain to be convinced that the Bishop on d7 isn't just simply on the wrong square! Sure, Black can play ...Bg4 but then it's not so easy for him: (9...cxd4 10.cxd4 Bc6 11.Qd3 0–0 12.0–0 e6 13.Ba3! Re8 (13...f5!? 14.e5 Rf7 15.Qb3! Bd5 16.Bc4 Nc6 17.Bxd5 Qxd5 (17...Na5 18.Bxe6! Nxb3 19.axb3+/- Bf8 20.d5 Bxa3 21.Rxa3 Kg7 22.Bxf7 Kxf7 23.Rd1) 18.Qxd5 exd5 19.Rfe1+/-) 14.Rfe1 Nd7 15.Rac1+/=) 10.0–0 Bg4 11.Be3 cxd4 (11...Nc6 12.d5! Bxf3 13.Bxf3 Ne5 14.Bxc5+/) 12.cxd4 Nc6 13.d5 Bxf3 14.Bxf3 Bxa1 (14...Ne5 15.Be2+/- f5 16.f4 Ng4 17.Bxg4 Bxa1 18.exf5 Bf6 19.fxg6 hxg6 20.Be6+ Kg7 21.f5+/-; 14...Na5 15.Rb1 b6 16.Qd3+/-) 15.Qxa1+/- Na5 16.Bh6 f6 17.Bxf8 Kxf8 18.Bg4+/- Jimenez Villena,F-Goormachtigh,J Benidorm 2003(18.Qb2+/-) 8.d5!

And so we arrive at Mikhailchishin's choice and Beliavsky's immediate response which takes full advantage of the Bishop still on f8. 8...Qa5 8...a6 9.Qa4!+/- Rb8 10.dxc6! axb5 11.Qxb5+-

9.Qa4! A superb move. The tactics work in favour of White: 9...Qxc3+ (only move) 9...Qxa4 10.Bxa4+10.Ke2 Bg7 A shell-shocked Mikhailchishin cannot believe that he is lost so quickly. Yet it is true! Perhaps 7....Nc6 just isn't playable after 6...c5, and as you can see, even top GM's don't know this! 10...Qxa1 11.dxc6 Kd8 12.Nf3 Qf6 (12...Bh6 13.Rd1+ Kc7 14.Bf4+ Bxf4 15.Rxa1) 13.Qa5+! b6 14.Qd2+ Qd6 15.Qc3!

and Rd1 comes next. A nice manoeuvre by the White Queen! 11.dxc6 0–0 12.Rb1 a6 He cannot bring himself to resign and scratches around for compensation. Against a lesser opponent maybe, but against Beliavsky he has no chance whatsoever. 12...bxc6 13.Bc4! Rd8 14.Qb3+13.Bd3 b5 14.Qa3! Qe5 15.Nf3 Qh5 15...Bg4 16.Bb2 Bxf3+ 17.gxf3 Qh5 18.Bxg7 Kxg7 19.Qc3++16.Be3 c4 17.Bc2 a5 18.Qc5 He could even take on e7: 18.Qxe7 Bg4 19.Qc5! 18...b4 19.Qxh5 gxh5 20.Bd4 Ba6 21.Bxg7 Kxg7 22.Ke3+- Rfc8 23.Ba4 Rab8 24.Rhd1 c3 25.Rd4 f6 26.e5 Bb5 27.exf6+ Kxf6 28.Rf4+ Kg7 29.Bxb5 Rxb5 30.Rc4 Rd5 31.a3 1–0

White players the world over are looking for ways to pressurize the Grunfeld. I think certainly that 6....c5 7 Bb5+ is the way to go and gives a small edge in every variation, whereas 6...Bg7 is far more common and then the status of 7 Bg5!? is most unclear. Perhaps you, the reader, would like to give these moves a try! My thanks to Jeremy Silman and his fine site, where part of this article has already appeared.

Kramnik,Vladimir (2758) - Kasparov,G (2851) [D85] Corus Wijk aan Zee NED Wijk (12), 29.01.2000 [notes by Tibor Karolyi] Kramnik's 8 h3 1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.cxd5 Nxd5 5.e4 Nxc3 6.bxc3 Bg7 7.Nf3 c5 8.h3

I recently read grandmaster Krasenkow's analysis of this game. He drew the conclusion that Kasparov comfortably equalized.

Looking back now it is easy to correct the judgement that he drew. White was always slightly better and Black never had a chance to win. What a gloomy prospect for Kasparov! Anyway, I have found it interesting to look at what has happened in Kramnik's line ever since. Kasparov, Anand and even Leko who used the Grunfeld all his life seem to stay away now. Could the line beginning with 8 h3 be the reason? Maybe not, but for the average mortal it might still work well. 8...0–0 9.Be2 The first game in my database is from way back: Gawlikowski-Taimanov Szcawno Zdroj 1950. But the line was dormant for three and a half decades. With 8 h3 White plans to develop the bishop and castle before he touches the central pawns. He does not want to be troubled by ...Bg4. How should Black use the time h3 gives him to undermine the centre? 9...b5

Black's main plans are connected with hitting the d4 or e4 pawns. Kasparov plays an original move which allows him to choose later on which he will attack. 10.Be3 Bb7 So Kasparov not only gained space on the queenside, but also put pressure on the e4. 11.Qd3 cxd4 11...Nd7!? 12.0–0 a5 Black defends b5 in an original way. 13.dxc5 (13.Rac1!? Deserves consideration as the rook steps out from the diagonal, in turn giving a freer hand in the centre. The speciality of the line, Qb1 might follow. 13...Rb8 14.Bf4+/=) 13...Qc8 14.Rab1 Nxc5 15.Qxb5 (15.Bxc5 Qxc5 16.Rxb5 Qc7 17.Qe3 Although Black often has enough for a pawn on the queenside, it is hard to say how much compensation Black has here. This time he fights for equality.) 15...Ba6 16.Qxc5 Bxe2 17.Rfc1 Bd3 Black held the position, Nikolaidis-Delchev, Cannes 2000. 12.cxd4 Nd7 13.0–0 Nb6 14.Qb1!

A strong move highlighting the drawback of Kasparov's play. The queenside becomes a target. 14.Bf4!? So that Nc4 will not come with a tempo. 14...f5 This leads to great complications. (14...Nc4 15.a4 The b5 pawn becomes a target.) 15.Qb3+ Kh8 16.Ne5 Bxe4 (16...Qxd4 17.Nf7+ Rxf7 18.Qxf7 Qxe4 19.Bf3 White is somewhat better.) 17.Bxb5 Nd5 The position is complex. 14...Na4 Kasparov finds a defence in simplification. 14...a6 15.a4 15.Qxb5 Nc3 16.Qxb7 Nxe2+ 17.Kh1 Nxd4 18.Rad1 e5 19.Nxe5 19.Nxd4!? exd4 20.Bxd4 Bxd4 21.Qb4

Kramnik probably should have tried this ending rather than the game continuation. Why? Because the existance of the queenside pawns favours White. Krasenkow thinks Black can hold, but it wouldn't be fun for him.

19...Bxe5 20.f4 Bg7 21.e5 21.Bxd4 Bxd4 22.Qb4 Rb8 23.Qxd4 White has chances to convert the advantage into a win. 21...Qb6! 22.Qxb6 axb6 23.Bxd4 Rxa2

24.Bxb6 Black can hold relatively easily as White can't avoid further exchanges of pawns. 24...Re8 24...g5 25.Bd8 It only temporarily stops exchanges. 25...Ra6 26.Bc7 Rae6 27.g4 g5 28.f5 Rc6 29.Rd7 Bxe5 30.Re1 f6 31.Bxe5 Rxe5 32.Rxe5 fxe5 33.Re7 h5 34.Kg2 hxg4 35.hxg4 Rc4 36.Kf3 Rf4+ 37.Kg3 e4 ½–½

Lalic,B (2531) - Karr,JP (2383) [D85] Open Cappelle la Grande FRA (7), 01.03.2001 [notes by Tibor Karolyi] 1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.Nf3 Bg7 5.cxd5 Nxd5 6.e4 Nxc3 7.bxc3 c5 8.h3 0–0 9.Be2 b6

A principled move. Black tries to find a plan where h2-h3 is a waste of time. This is not certain; White's centre looks steady. 10.Be3 Bb7 11.Qd3 cxd4 Black can hold back taking, however this move is the most popular. 11...Nd7 12.0–0 Nf6 13.Nd2 Qd7 14.a4 Rfd8 15.a5 cxd4 16.cxd4 e6 17.Rfb1 White has pressure on the queenside, Golod-Svidler, P, Blitz 2000.; 11...Qc7 12.0–0 Rd8 (12...Nd7 13.Rac1 e6 14.e5 Rac8 15.Ng5 Rfd8 16.Qb1 Nb8 17.Ne4 White is a bit better, Kruppa-Elianov, Elista 2000.) 13.Rfd1 Nd7 14.Qb1 (14.a4) 14...h6 15.a4 e6 16.Ra2 Rac8 17.d5 exd5 18.exd5 c4 19.a5 White has a small advantage, Buhmann-Schulze, Germany 2000.; 11...Ba6 12.Qd2 Qd7 (12...Bxe2 13.Qxe2 Nc6 14.Rd1 (14.0–0 cxd4 15.cxd4 Nxd4 16.Bxd4 Bxd4 17.Rad1 e5 18.Nxe5 Qc7 19.Nxf7 Bxf2+ White's advantage will be insignificant.) 14...cxd4 15.cxd4 Rc8 16.0–0 Na5 17.d5 Qd7 18.Bd4 Qa4 19.Bxg7 Kxg7 20.e5 Rfd8 21.Rd4 Qc2 22.Qe3

Lazarev,V (2505) - Dvoirys,S (2568) [D85] 17th Open Geneva SUI (3), 22.01.2001 [notes by Tibor Karolyi] 1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.Nf3 Bg7 5.cxd5 Nxd5 6.e4 Nxc3 7.bxc3 c5 8.h3 0–0 9.Be2 cxd4 9...Nc6 Black can play without exchanging the c pawns. 10.Be3 Qa5 11.Bd2 (11.0–0 Rd8 Black has a grip on the centre.; 11.Qd2 Rd8 Here he has it as well.) 11...cxd4 12.d5 looks dangerous, so Black probably has nothing better than enter to a main line. 12.cxd4 Qa3 10.cxd4 Nc6

This is the most common move, in a way most in the spirit of the Grunfeld. Black wastes no time putting pressure on d4. In this line h3 has a function stopping the f3 knight from being pinned. Black must do something quickly otherwise White's centre will dominate. 11.Be3 Qa5+ Black plays like they often do in the main lines. This move intends to confuse White's pieces a bit. 11...f5!?

A move which scores well for Black yet White can establish a small advantage without any risk:12.exf5 (12.Qb3+ Kh8 13.Rd1 (13.exf5 Qa5+ 14.Bd2 Qxf5 15.Qe3 Be6= Mikanovic-Turov, Quebec 2001.) 13...fxe4 14.Ng5 Nxd4 15.Qc4 Qa5+ 16.Rd2 Nxe2 (16...e6!?) 17.Nf7+ Rxf7 18.Qxf7 Bd7µ Arencibia-Elianov, Ubeda 2001.) 12...Qa5+ 13.Qd2 Qxd2+ 14.Kxd2 Bxf5 15.Bc4+ Kh8 16.Rhd1 (16.Rad1!?+/= White is a fraction better.) 16...Na5 (16...Bxh3 Black should be not worse with the extra pawn.) 17.Bd3 Rad8 18.Ke2+/=

White has a small edge, Grachev-Belov, Russia 2002. 12.Bd2 Qa3 13.d5 Ne5 13...Bxa1 14.Qxa1 Nb4 15.0–0 f6 16.Rc1 (16.Bc4!?) 16...a5 17.Bb5 b6 18.Rc3 Qxa2 19.Qxa2 Nxa2 20.Ra3 Nb4 21.Bxb4 Ba6 22.Bxe7

White is somewhat better, Hoeksma-Ernst, 2000 Dieren. 14.Nxe5 14.0–0 Bxh3 (14...Bd7 Even simpler is this developing move. 15.Nd4 Rfc8 16.Qb3 Qxb3 17.axb3 Nd3 Black has an easy game, Hoffmann-Ricardi, Argentina 2001.) 15.Nxe5 Bxe5 16.Rb1 Bc8 17.Bb4 Qxa2 18.Bxe7 Re8 19.d6 Qe6 20.f4 Bg7 21.e5 Rxe7 22.dxe7 Qxe7 23.Ba6 Bf8 24.Qf3 Qd8 Grandmaster Dvoirys held the position with Black against Belov, Poen Ano Liosia 2001. 14...Bxe5 15.Rb1 15.0–0 Rd8 (15...Bd7 16.Rb1 Transposes to the game.) 16.Rb1 Qxa2 17.Bb4 e6 18.f4 Bd6 19.Bc3 Qa3 20.Rb3 Qa4 21.Bf6 Rf8 22.e5 Bc5+ 23.Kh1 exd5 24.f5

White's ferocious play led to Black's defeat in 5 more moves, Pedersen, NV-Sigfussion, N, Budapest First Saturday.

15...Qxa2 15...Bd7 16.Rxb7+/= 16.0–0 Bd7 16...b6 This was played only once, so I feel it is too early to evaluate the position. White should have compensation for the pawn. 17.f4 a) 17.Bh6 Rd8 18.f4 Bh8 Unclear Pushkov-Shipov, Elista 2001.; b) 17.Bb4 Bf6 18.f4 With a complex game.(18.Bb5 a5 19.Bd2) ; 17...Bd4+ 18.Kh2 a5 19.Bb5 This position needs practical tests. 17.Rxb7 Ba4 18.Qe1 18.Qc1 has not been tried, it leads to an interesting position: 18...Rac8 (18...Rfc8 19.Rxa7) 19.Qe1 Bc2 20.Bh6 Rfe8 21.Qd2 18...Rfb8 19.Rxb8+ 19.Rb4 or 19.Rb7 have been tried but they are only good for a draw. 19...Rxb8 20.Be3 Bc2 21.Qd2 a5 This keeps the position balanced. 22.f4 Bd6 23.e5 Bb4 24.Qd4 Be4 25.Qxe4 Qxe2 26.Rf2 Qb5 27.f5 Bc3 28.e6 Qb1+ 29.Qxb1 Rxb1+ 30.Kh2 Be5+ ½–½ It is very hard to draw conclusions on this particular line with h3 and Be2. There is no clear way found to neutralise it or kill the play. It is worth trying occasionally. If you are playing Black, you need serious advance preparation or expensive losses may follow.
