A new way to counter

the Perenyi Attack

By IM Merijn van Delft & IM Robert Ris

Frequency

This week we cover the exciting last round of Nalchik,

the French and Italian Leagues and the tournaments

in Dubai and Benidorm. Special attention goes out to

the young French star Maxime Vachier-Lagrave who

scored an impressive 4 out of 4 for his team.

WHAT’S HOT?

The last round of the FIDE Grand Prix in Nalchik featured some fascinating

opening choices. Svidler-Grischuk was a French Winawer that ended in

a quick draw, with the twist that Black played a line that we thought to be

refuted (details below). As we pointed out in CVO 12, Gelfand is possibly

the greatest expert on beating the Chebanenko Slav. The ultimate prove

was his win over arguably the biggest expert on the Black side, Karjakin.

The tournament was decided in Aronian-Leko, a game that had it all.

Score

The strong French League provided several notable novelties. Our Game of

the Week for instance was a hardcore battle in the Najdorf Perenyi Attack.

In the diagram position Vachier-Lagrave came up with the new move order

8...¤c6!?. Naiditsch was successful with the currently fashionable 6.h3

against the Najdorf and Berg (in Benidorm) with his favourite 6.¥g5.

Nijboer-Stellwagen was an exciting theoretical duel in the Caro-Kann

Advance Variation. Fontaine-Landa was also fascinating, but Black

seemed to have simply forgotten the theory. Komarov-Naiditsch saw new

developments in the Vienna. In the Italian League, Kiril Georgiev showed

impressive technique after repeating the tricky concept from last week ’ s

Kasimdzhanov-Aronian. In Dubai, Volkov tried an interesting pawn sacrifice

in the French (see the PGN file).

This week a heated discussion took place on ChessVibes.com concerning the Petroff. Whether the opening is boring or not, at the moment

it is definitely not hot. Last week we had Leko with two crushing wins and this week White has

scored 3.5 out of 4 against the Petroff at grandmaster level. In Bacrot-Alekseev, Black should

have played the prophylactic 6...h6.

A new move order in the Perenyi

Basically Black is theoretically OK in the Perenyi Attack, but in practice it is not so easy to be on

the defending side facing all those piece sacriices. With a completely new move order Vachier-

Lagrave tries to take the sting out of White’s attack.

The Pereny Attack is one of the sharpest

variations against the Najdorf and has been

popularized by attacking players like Kotronias

and Shirov already two decades ago. The

main alternative is 7.f3 leading to the English

attack, while 7.¥e2 most likely transposes to the

classical Scheveningen.

Black mainly opted for more direct approaches:

a) 8...g6

critical branch in the Perenyi) 11.g5 was the

In CVO 12 we analysed Morozevich ’ tricky 6...£b6, but the main line is still 6...cxd4 7.¤xd4 ¤e7. While 8.c4 is

the most frequently played move, Nijboer consistently plays 8.¥g5 and not with bad results. Against Erenburg

and Postny he faced the more solid 8...£d7 before, and now in Nijboer-Stellwagen, French League 2009 the

sharp 8...£a5 was tested again. This stuff is mainly known from the fantastic encounter Motylev-Bareev, Moscow

2005, but Nijboer was the first to get his novelty in with 10.¤bd5!?. Stellwagen reacted well by exchanging the

dark-squared bishops, not fearing to have his king stuck in the centre. At first sight the knight invasion looked

very promising, but after some consolidating moves Stellwagen could eliminate it. After that, Black had the better

prospects and Nijboer admitted that his countryman let him escape from a highly dubious situation. A tense

struggle not untypical for the Caro-Kann Advance Variation!

As we noted last week, the Winawer is back! The positions in the gambit line 7...cxd4 (or 7...£c7) are very difficult

to handle in practice. Actually we had the impression that White is doing well against 7...0–0 lately. To our surprise

Grischuk played 8...£a5 against Svidler, a line we thought to be refuted! The following spectacular line was a

joint effort and has been published before in both the late Dutch magazine Schaaknieuws (Van Delft) and the

Rybka 3 book (Noomen): 9.¥d2 ¤bc6 10.¤f3 f5 11.exf6 ¦xf6 12.£h5 ¤f5 13.c4! (stronger than the direct 13.g4)

Aronian-Leko was a most impressive all-decisive last round encounter. Both players were sharing first place a

full point ahead of the rest. Many chess fans expected a quick “grandmaster draw” and most chess professionals

would have used the white pieces to test the opponent in a well-prepared theoretical line and settle for the draw

as soon as Black had survived the test. It was not the opening itself that was particularly interesting, but the

opening choice of Aronian to just go for an unclear position without forced lines that was admirable. Leko looked

excellently prepared throughout the tournament and now he was forced to play chess from the start. After the

Nimzo-Indian with 4.e3 appeared on the board, the ¥ pair against the ¤ pair seemed to be a tricky balance,

which may have been disturbed at first after the unforced 24...¥c4?!. The active Black pieces were pushed back

and with the positional exchange sacrifice 34.¦e5! White got into total control.

In CVO 17 we mentioned that Black seems to be doing fine in the Vienna. Apart from 6...dxc4, Black has another

sharp line with 6...b5 at his disposal. The character of play is more risky and since Kramnik ’ s novelty 14.axb5!

the line was considered to be dead for Black. Last summer Ivanchuk introduced a new idea and comfortably

equalized with Black against Gustafsson. Komarov ’ s 20.£e2 was an unfortunate error, after which Naiditsch

seized the initiative and won the game smoothly. We don ’ t like 17.¤e4 that much, because the ¤ doesn ’ t have a

clear function (in fact it only blocks his own ¥). Possibly 17.¤f5!? is still an interesting try, although it doesn ’ t lead

to a clear edge for White. All in all an excellent surprise weapon in a must-win situation for Black!

Who:

Maxime Vachier-Lagrave

Born:

October 21, 1990

Nationality:

France

Rating:

2684

Expertise:

Najdorf and Grünfeld

Why:

The young Frenchman has spent most of his career so far in the shadow

of his age mates Carlsen and Karjakin. One can see similarities in chess

style with the legendary Garry Kasparov: Vachier-Lagrave prefers a

sharp tactical fight and is not too shy to take the necessary risks, and

consequently plays the same openings as ‘The Boss’. The following

game, played last weekend in the French team competition (where

Vachier-Lagrave scored an impressive 4 out of 4), is a nice example of

what the White player is capable of with his pieces. An early exchange of

queens doesn’t necessarily mean an easy life, as Spanish GM Magem

discovered.
