Bulgarian opening
specialities
By IM Merijn van Delft and IM Robert Ris
In this issue of CVO we take a look at the irst ive rounds
of the European Team Championship that's currently
taking place in Greece. At this point the tournament sees
Bulgaria, headed by Topalov, as the sole leaders.

hot?
Score
Topalov beat Svidler in the 8.h3 Anti-Marshall. Sune Berg Hansen
managed to outplay Aronian in the Italian Game, but instead of delivering
mate, he was suddenly checkmated himself in time trouble. Sulskis'
5.g4!? against the French Rubinstein isn't new, but does deserve
attention. Shirov is making a living out of winning with the Caro-Kann
Advance Variation in as many different ways as possible.
Morozevich's 7...g5!? in the 3.¥b5+ Sicilian backfired completely
against Delchev. Naiditsch is doing a good job with his Najdorf: check
out his wins against Djukic and Ponomariov. Below we take a look at the
Najdorf mysteries Karjakin-Cheparinov (English Attack) and Solak-Van
Wely (Polugaevsky).
In the top rated game Aronian-Radjabov Black equalized with the QGD.
Ragger won a good game with Black against Nyback's Slow Slav. In our
Game of the Week
, Gustafsson-Efimenko, Black was checkmated in
the Ragozin Variation. In the diagram position Black went for 9...¥xc3+.
The Bulgarians made the 5.e4 gambit against the Vienna Variation their
speciality (see below). Black scored 50% from the Grünfeld top level
encounters Navara-Svidler, Wojtaszek-Nyback and Vachier Lagrave-
Sutovsky. Banikas-Radjabov was a relevant King's Indian main line.
Source: Megabase + TWIC, 2500+ only
Black was under pressure in the 1.d4 d5 2.c4 c6 3.¤c3 dxc4 Slav this week, as can be seen from the games Gustafsson-Balogh
and Mamedyarov-Brunello, which we'll discuss below. This is potentially bad news for Slav practitioners, as after the main alternative
3...¤f6 4.e3 they don't reach their opening. 4...¥f5 is not good in that case and moves like 4...a6 and 4...
g6 lead to a different kind of Slav, which may not be to the liking of proper Slav players.

Beating the Ragozin
The Ragozin Variation seems to be in theoretically ine shape, but holding in a practical
game can be an entirely different story. When Gustafsson started a ierce attack, Eimenko
soon missed the best defence and was checkmated.

D37 Ragozin
18.£e1 h6 19.¥f4 £e7 20.£h4 ¤c4
Black had better refrain from the tempting 20...
g5?! because after 21.¥xg5 hxg5 22.£xg5+
¢h8 23.£h6+ ¢g8 24.¦fe1! he fails to get rid
of the pressure.

27.¦c7 and White retains the better chances
due to his pair of ¥s and his passed pawn.
24.¥xh6
A spectacular blow, which only leads to a
draw with correct play. However, nothing could
have been gained by a preparatory move like
24.¦ce1 when Black can neutralize White
'
s
initiative with 24...¤d5!.
24...¤xe4
24...gxh6? is bad because of the simple 25.¦xf6
and White retains a devastating attack without
investing any material.

25...¤f6?
This move allows White to finish the game in
style. Black should instead have played 25...

'
s apparently no win for White:
26.¥xe4 (26.¦ce1 ¤cd6 27.¥xe4 (27.£xh6?
£g5!–+) 27...¤xe4 28.¦xe4 £xe4 29.£xf7+
¢h8 30.£f6+ and White has to repeat moves.)
26...¤d2 (26...£xe4?! 27.£xf7+ ¢h8 28.£xd7
and White is a healthy pawn up, but not 28.¦f6?
£e3+! and Black even wins.) 27.¥d5 (After
27.¥h7+ ¢g7 28.¥f5 ¤xf1 29.¦xf1 £e3+
30.¢h1 £f4 31.¢g1 £e3+ White also has
to accept a draw.) 27...£e3+ 28.¢h1 ¤xf1

26.¦xf6! £xf6
26...gxf6 27.¥h7+! ¢h8 (27...¢xh7 28.¥f8+
wins the £.) 28.¥f5 and soon mate will follow.
27.¥h7+!
This pretty move might have been overlooked
by Efimenko in his calculations. Inferior is
27.¥g5? g6! and Black stays alive.
27...¢f8
Other ¢ moves wouldn

either: 27...¢xh7 28.¥g5++–; 27...¢h8 28.¥g5

29.¥g6+ and White wins.
28.¥g5 ¦e5
28...£e5 is strongly met by 29.¥d3! f6 30.¥xc4

9...¥xc3+
The most fashionable continuation. The
alternative is 9...¤e4 which was played in
Kramnik-Ponomariov amongst others and has
been covered in CVO 46, 82 and 84.
10.bxc3 0–0 11.¤d4 ¤e4 12.¥f4 ¦e8
a) 12...£xa2 13.¦c2 £a5 was recently played
in Eljanov-Moiseenko, Saratov 2011 and now
instead of 14.¤b5? our improvement is 14.c6!
which was suggested in CVO 146. 12...¤dxc5
13.f3 ¤f6 14.£d2 ¥d7 15.c4 favored White in
Le Quang Liem-Peralta, Mulhouse 2011. A
game quiz was produced around this model
game for CVT 8.
13.¥e2
The immediate 13.¥d3 is less precise, since
after 13...¤dxc5 White has to make another
move with his ¥.
13...£xc5
A novelty. In an earlier game Black failed to
reach equality after 13...¤dxc5 14.f3 ¤f6
15.¤b5 ¤e6 16.¥e5 ¤d7 17.¥g3 ¤b6 18.0–0²
Cmilyte-Koneru, Moscow rapid 2011.
14.0–0 ¤b6 15.¥d3 ¥d7 16.f3 ¤f6 17.¥g5
£d6
Another option is 17...£e7 when White keeps
an edge after 18.¦e1! (but not 18.£e1?! h6! and
the weakness of the pawn on e3 can be felt.)

The diagram position was reached in one of the most important games at the European Team Championship,
Karjakin-Cheparinov, which helped the Bulgarians beat the Russians 3–1. 19.¢b1 was the first new move and
Black replied with the logical 19...¥g7. Without knowing any details, one wonders why White would ever want to
play a position like this, with a powerful unopposed ¥ on g7 and the long diagonal opened by b3. Black's ¢ on e8
is also much safer than usual in the Sicilian. When the queens came off Black had a very good endgame which
he indeed went on to win. Just like Solak-Van Wely, which you can also find on this page, we have another
theoretical mystery. Karjakin belongs to the absolute elite and plays the Najdorf with both colours, but here even
a player of his class got lost in a swamp of information. Hopefully we'll soon get to see this line again at the
highest level, and see what's really going on here.
1.e4 c5 2.¤f3 d6 3.d4 cxd4 4.¤xd4 ¤f6 5.¤c3 a6 6.¥g5 e6 7.f4 b5 8.e5 dxe5 9.fxe5 £c7 10.exf6 £e5+

In the pre-computer era the famous grandmaster Polugaevsky spent months repairing his variation against
assaults by players like Tal. It's had a reputation of being 'basically refuted' for decades, but with every new
generation of engines everything has to be checked again. In Solak-Van Wely the diagram position was reached
and here White went for 19.fxg7, a move that is known to lead to a rook ending (!) which Black can draw without
too many problems. It has also been known for a few years now that 19.a4! b4 20.¦xb4! transposes back to the
important game Leko-Ghaem Maghami, Yerevan 2001, which is very good for White. Note that 17.¦ab1! is in
fact the most accurate move order, since it prevents the black £ from escaping via b4. Last year I (MvD) used
this line to score a quick win against Rietveld. Did Van Wely know about these problems and did he use the
Polugaevsky as a surprise weapon? Or does he have an improvement somewhere? I couldn't find a defence
for Black so far. Time will tell.

The Slav with 3...dxc4 has been serving Black quite well in the last couple of months. Despite Vallejo's
painful loss against Aronian (CVO 143), Black seems to be doing fine in the complications arising from 4.e4
b5 5.a4 b4 6.¤b1 ¥a6 7.£c2, while the alternative 6.¤a2 also hasn't brought White any successes lately
(CVO 134). Therefore new ideas have to be explored and recently White scored two important victories with
4.e3. Mamedyarov completely crushed the Italian Brunello with the novelty 11.¤d2! improving upon the game
Avrukh-Guramishvili. The PGN-file shows that 8...e5 is currently in a critical state. Hence, the Hungarian expert
Balogh prefers 8...¥a6 which he successfully employed earlier this year against Yu Yangyi. The Chinese GM
avoided a repetition of moves and eventually lost that game. This time Gustafsson attempted to improve with
13.0–0 and quickly seized the initiative. In the diagram position Black committed a serious error with 19...exf4?,
after which he gradually went down. Instead, 19...¤c5! would have led to unclear complications.
1.d4 e6 2.c4 ¤f6 3.¤f3 d5 4.¤c3 dxc4 5.e4 ¥b4 6.¥xc4 ¤xe4 7.0–0 ¤xc3 8.bxc3 ¥e7 9.¤e5 0–0 10.£g4 ¤c6

Since the game Aronian-Anand, Bilbao 2011, where the Armenian crushed the current World Champion in
25 moves, the Vienna with 6.¥xc4 has also drawn interest from other top players. This week three important
theoretical encounters were played in the variation 6...¤xe4 7.0–0 ¤xc3 (Anand's choice of 7...¤f6 is less
appealing) 8.bxc3 when the most common retreat is 8...¥e7. In Sulskis-Lupulescu, Black went for 8...¥d6 which
is pretty dangerous because of 9.¤g5! when White seizes the initiative on the kingside. In several earlier games
an immediate repetition of moves had been forced, though Sulskis' novelty 11.¦e1! seems more challenging.
After 8...¥e7, Topalov introduced the new idea 9.¦e1 0–0 10.h4, but Pelletier didn't crack under the pressure and
in fact managed to hold a convincing draw. In Cheparinov-Meier, another of the Bulgarian's ideas was revealed
with 12.¦ae1 after which his opponent faced a strong attack on his ¢. Something has probably gone wrong
with the notation, as the game abruptly finished on move 27 in a position where Black could still have fought on.

Baron-Mamedov, Corsica Masters, 2011
A fairly normal Sicilian structure where Black has managed to activate his ¤ to c4 and White has failed to generate
active play on the kingside. The following idea is a typical idea to make progress in this kind of structure.
21...d5!
22.e5
After 22.exd5 ¤xd5 23.¤xd5 ¥xd5 24.¥xd5 ¦xd5 Black retains a stable advantage thanks to his better
structure and superior minor pieces.
22...¤e4 23.¥xe4
The ¥ has to be eliminated due to the threat of ...¤f2.
23...
dxe4 24.£e2 ¥b4?!
A more challenging continuation might have been 24...e3!? with the idea of meeting 25.¥xe3
with 25...¤xb2! when Black
’
s advantage is indisputable.
25.¦a4 a5 26.¦d1?
The decisive mistake. White should
have tried 26.¤xa5 ¥xa5 27.¦xc4 £e7 when Black has sufficient compensation, but probably no more than that.
26...¦xd1+ 27.¤xd1 ¥a6 28.£xe4 ¦d8 29.¤f2 ¥b7 30.£e2 £c6
and Black won.

Wang Hao-Ding Liren, Chinese League (Qingdao), 2011
In this typical King's Indian position White played an even more typical exchange sacrifice:
25.¦cc6! a3
Accepting the sacrifice also gives White a clear edge: 25...¥xc6 26.dxc6 ¦c7 (26...¦bb8 27.¦xa4±) 27.£xb4±.
