A very special Najdorf | ChessBase

The Polugaevsky variant

Petra Papp updates a very special Najdorf

The Polugaevsky variant in the Najdorf comes after 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 e6 7.f4 b5against which I recommend the main line 8.e5! for White.

The first time 7…b5 was played in top level chess in 1957. Two years later, Lev Polugaevsky, the Soviet grand grandmaster who was one of the strongest players in the world from the early 1960s to the late 1980s, started to energize this variation, employing it successfully in his own practice and finding many interesting ideas (see Novopashin,A – Polugaevsky,L ½-½). After its games, 7…b5 became known as the Polugaevsky Variation.

Nowadays, the Polugaevsky variant is no longer fashionable at the highest level. Wassily Ivanchuk played there occasionally several years ago, later also Jeffery Xiong, but mainly in blitz games, while Gergely Aczel, a powerful Hungarian GM, took over 7…b5 Only recently. Thanks to the super powerful engines, the line is practically refuted, so if White is booked in theory, they will have a great advantage. Nevertheless, it is still dangerous, because white must know the precise moves.

From the diagram follows 8…dxe5 9.fxe5 Qc7. A central idea of ​​this line. The black queen comes out of the keel, generating a tactical threat to reclaim the piece after capture: 10.exf6 Qe5+ 11.Be2! Qxg5 12.0-0.

Until then, everything was forced. White has a more developed position, but converting this advantage is not easy. I will investigate Black’s A) 12…Qe5?! and B) 12…Ra7.

A) 12…Qe5?!

The second most popular move, but this is already a mistake. Black tries to pressure the knight on d4 with the threat of Bc5. However, in some lines, the black queen and king can come into the line of sight on the electronic file. 13.Kh1! It helps to remove the king from the weakened g1-a7 diagonal. 13…Bc5 14.fxg7! Qxg7 and now White has a nice attacking move: 15.Nf5!

(intention 15…exf5 16.Qd5) with an excellent position, see Crosa Coll,M – Coelho,L 1-0.

B) 12…Ra7

This marvelous movement is the key idea of ​​the Polugaevsky variation. Black brings his turn into the game via the 7th rank, offering quick defense and counterplay. Of course, this move was discovered by none other than Lev Polugaevsky himself. 13.Qd3! The strongest answer. White must control squares e4 and e3. Their next plan is to play Ne4 hitting Black’s queen. 13…Rd7 14.Ne4!.

14…Of5. This is the main move, Black puts pressure on the two knights in the middle. (There are 14…Qg6?! take the queen away from the queen. 15.Bf3! White protects the knight on e4, making his queen mobile. 15…Bb7 and now after the coin sacrifice 16.Qc3!! Bxe4 17.Rae1 !!

White won a creative attacking game at Szczepankiewicz,D – Gesicki,J 1-0).

15.Nf3!.

Retreating the knight to f3 gains tempo. This is the critical position of the whole line. I will investigate the queen’s movements B1) 15…Qc7 and B2) 15…Qxb2.

B1) 15…Qc7 is quite solid, but it’s still easy for white to show a stable advantage: 16.Qe3! Qa7 17.Qxa7 Rxa7 18.Nfg5!.

Even after the queen exchange, White’s game remains very active. 18…g6 19.c4! Using the b5 hook to open the queenside is a common idea, see Pasti,A – Aczel,G 1/2.

B2) 15…Qxb2. Capture what is often considered a poisoned pawn. This should also give White a clear advantage, but White must already be very familiar with dynamic attacking moves. 16.Qe3! Bb7 17.Rab1!.

The queen on b2 is strong, so it is important to deflect her. This is another critical line of the Polugaevsky variant, with one final branch:

B21) 17…Qxc2 18.Nfg5!!.

A very powerful all-round move. The knight protects his colleague on e4 and simultaneously attacks Black’s vulnerable kingside. Now 18…Qc7 is the most natural, but after 19.Rbc1 Qe5 20.Bg4 !!

White has a lot of play.

And if black blocks the kingside with 18…g6?white can open the position with 19.Rbc1! Da4 and now 20.Nxe6 !!

winner – all these lines are checked in the game Negi,P – Hermansson,E 1-0.

B22) 17…Qxa2

After this capture, I think white has two equally good moves giving more than enough compensation for the sacrificed pawns: 18.Nfg5 and 18.Kh1. These two sequences are carefully examined in the game Abdumalik,Z – Kamalidenova,M 1-0.

Summary: 6.Bg5 is one of the sharpest moves against the Najdorf. The Polugaevsky Variation 7…b5 is objectively not recommendable for Black, but leads to sharp and difficult lines that can lead to surprise. White usually has to sacrifice material to attack the black king. I think the strongest way for black is 15…Qc7 followed by 16…Qa7 to swap queens, although this allows white to open the queenside with the standard c2- pawn breaks. c4 or a2-a4. A typical attack move for the first player is Nfg5!. From what I have analyzed in this article, if white knows all these precise moves and ideas, he will have a much better position on the opening exit! 🙂
