Larry Christiansen
is a Grandmaster.
Larry has been one of the foremost figures of American chess for many years. A Grandmaster
since 1977, Larry is well-known as a fearsome attacking player. He has downed many of the
world's elite players, including a 12-move victory against ex World Champion Anatoly Karpov!
Larry has been a mainstay of the American national team, competing in numerous Olympiads
and team championships. He was a member of the team that won the World Team
Championship in 1993.
As well as playing in tournaments and team events all over the world, Larry is a successful writer
on the game, and his books "Storming the Barricades" and "Rocking the Ramparts" have
introduced chess players to his unique brand of aggressive chess.
Introduction and 9...Qa5+ [B33]
The Sveshnikov Sicilian has long been a popular fighting defence and has survived many
attempts at refutation. The latest craze in the line involves the move order
1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 6.Ndb5 d6 7.Bg5 a6 8.Na3 b5 9.Nd5
which will be the focus of our discussion here on TWIC. For the sake of convenience, I will adjust
all games mentioned in this article to conform with this standard move order, although of course
many games start 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e6 6. Ndb5 d6 7. Bf4 e5 8.
Bg5 a6 9. Na3 b5 10. Nd5
In my younger days I played the Sveshnikov Variation with both colours and I have a healthy
respect for this dynamic variation. Except for the Najdorf, it is unquestionably Black's most
dynamic fighting defence to 1. e4. My main attention will be on the answer 9...Be7
but of course Black has an interesting option with
9...Qa5+
which evades the pin on f6.
Nowadays,
10.Bd2
is an almost automatic answer
but the gambit 10.c3!? is interesting and very tricky. White seems to have a promising position
after 10...Nxd5 (The real test of 10. c3 is to grab a pawn with 10...Nxe4 while attacking the bishop
on g5. Then 11.b4?
a)
Also dubious is 11.Nxb5 axb5 12.Bxb5 Bd7 13.b4 Qa7 14.Be3 Qb7 15.a4
Nd4!;
b)
The best try for White is 11.Be3 Rb8 12.Nc2 intending to undermine Black's queenside
with a subsequent a2-a4 while also setting up tactics involving Bb6 Rxb6 b4.
(12.Qf3 f5!
is strong
;
and
12.Bd3 Nc5
does not give White enough for the pawn
)
One fun line goes 12...Ne7!? (After
12.Nc2, a more solid continuation for Black is 12...Be6 when 13.Ncb4 Nxb4 14.Nxb4
(14.cxb4
Qd8 15.Rc1 Rb7
is fine for Black
)
14...Rc8 15.a4! Nxc3! 16.bxc3 Rxc3 17.axb5 there is nothing
better 17...Qxb4 18.Bd2 axb5
(18...Qe4+;
and
18...a5
are also reasonable
)
19.Bxb5+ Qxb5
20.Bxc3 Qc6! 21.Qa4 Qxa4 22.Rxa4 leads to a favourable ending for Black.
Which explains why 10.Bd2! is an almost automatic move.) 13.Bb6 Rxb6 14.b4 Nxd5 15.bxa5
Ndxc3 16.Qd3 Rc6 17.a4
(17.f3 Nf6
is unclear - Black has two pieces and two pawns for the
queen with a very active game
)
17...d5! 18.axb5 Bc5! 19.Ne3
(19.bxc6?? Bxf2#)
19...Nxb5 with
chances for both sides.; 11...Qxa3 12.Bc1 Nxc3 13.Nc7+ Kd8 14.Bxa3 Nxd1 15.Nxa8 Nc3
16.Rc1 Bb7 17.Rxc3 Bxa8 is clearly good for Black.) 11.exd5 Ne7 12.Bd3! Then, if Black plays
12...h6? 13.Bd2! White is primed to play a quick c3-c4 tearing open the queenside.
After
10...Qd8
the sharpest continuation for White is
11.c4 Nxe4 12.cxb5 Be6! 13.Bc4 Ne7 14.Be3
14.0Î0 Bxd5 15.Bxd5 Nxd5 16.Ba5! Ndc3! 17.Bxc3 Nxc3 18.bxc3 d5! 19.Qb3 Bxa3 20.Qxa3
axb5 21.Qc5 Rc8 22.Qxb5+ Qd7 23.c4 Qxb5 24.cxb5 Kd7 25.a4 Rc5!
leads to a double-edged
double-rook ending with chances for both sides
14...Rc8
(Kasparov)
15.Nb6 d5!
And now two recent games:
16.Qa4
16.Nxc8 Nxc8 17.Bd3 Qa5+ 18.Kf1 Bxa3 19.bxa3 0Î0 20.Qb3 axb5
(20...d4 21.Qb4 Qxb4
22.axb4 Bf5!
looks fine for Black
)
21.Qxb5 Qc3?
(21...Qxb5 22.Bxb5 d4 23.Bc1 Ncd6
gives Black
fine compensation for the exchange. I would rate that +/= at best.
)
22.Rc1 Qxa3 23.Bxe4 dxe4
24.Qxe5 with a clear edge for White, Am Rodriguez-Llorens, Santiago 2005.
16...dxc4 17.Rd1 Nd5! 18.bxa6+ Bd7 19.Nxd7 Bb4+ 20.Kf1
20.Bd2!? Bxd2+ 21.Rxd2 Nxd2! 22.Nb6+ Ke7 23.Nxc8+ Qxc8 24.Qa5! Rd8 25.Qxd2 c3 26.Qg5+
Kf8 27.0Î0 cxb2 28.Qxe5 Qc3 29.Qg3=/+
is at least equal for Black
20...Qxd7 21.Qxd7+ Kxd7 22.Rxd5+ Ke6 23.Rb5 Bxa3 24.bxa3 Nc3 25.Rb6+ Kd7 26.a7 Nd5
27.Rb7+ Kc6 28.Rxf7 Nxe3+ 29.fxe3 Rhf8 30.Rxf8 Rxf8+ 31.Ke2 Ra8
and Black held a plus in the ending, Dominguez-Radjabov, Tripoli 2004
In conclusion, 9...Qa5+ remains a good, albeit complicated, answer to White's move order.
11.c3 Ne7 [B33]
1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 6.Ndb5 d6 7.Bg5 a6 8.Na3 b5 9.Nd5
Instead of 9...Qa5+, most Sveshnikovers play
9...Be7
setting up
10.Bxf6 Bxf6 11.c3
White occupies d5 and looks forward to bringing his bad knight into the game with Nc2. He had
other ideas like a2-a4 to weaken Black. Black is interested in creating kingside play with an
eventual ...f7-f5, working around that powerful knight on d5. Black has four main ideas after 11.c3
11...Ne7
The idea behind 11...Ne7 is simple enough - he plays to trade off the powerful outposted knight.
11...Bb7;
11...Bg5;
11...0Î0 are covered below
White's only promising continuation now is
12.Nxf6+ gxf6
and here he must choose between 13. Nc2, 13. Bd3 and the solid 13. g3.
13.g3
The Russian GM Korneev has had great success with 13. g3 - White's aim with that move is to
support e4 while eliminating counterplay on the g-file.
13. Nc2 is favoured by the Icelandic GM Steffansson,
while 13. Bd3 is favoured by the likes of Nick de Firmian, Jonathan Rowson and Sergei Tiviakov.
Rummaging through the various databases I would tend to favour 13. Bd3 or 13. g3 myself. The
play is relatively controlled compared with many wild lines of the Sveshnikov. Here are some
recent offerings with comments by me:
