A very special Najdorf

by ChessBase
5/10/2022 – When White wants to tackle the Sicilian Najdorf Variation — 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 — very directly, 6.Bg5 is a popular choice. After 6...e6 7.f4 the rare 7...b5, the Polugaevsky Variation, leads to sharp and difficult positions. Petra Papp brings the theory of this variation up to date in her article for ChessBase Magazine #207, explaining typical strategies and motifs for both sides.

The Polugaevsky Variation

Petra Papp updates a very special Najdorf

The Polugaevsky Variation in the Najdorf arises after 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 e6 7.f4 b5, against which I recommend the main line 8.e5! for White.

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

Nowadays, the Polugaevsky Variation is not fashionable at top level anymore. Vassily Ivanchuk used to play it occasionally several years ago, later also Jeffery Xiong, but mainly in blitz games, while Gergely Aczel, a strong Hungarian GM has taken up 7...b5 only recently. Thanks to the super strong engines, the line is all but refuted, so if White is booked-up on theory, they will enjoy a great advantage. Still, it remains dangerous, because White must know the precise moves.

From the diagram follows 8...dxe5 9.fxe5 Qc7. A central idea of this line. Black's queen steps out of the pin, generating a tactical threat in order to win back the piece after the capture: 10.exf6 Qe5+ 11.Be2! Qxg5 12.0-0.

Up to this point, everything was forced. White has a better 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 it's already a mistake. Black is trying to pressure the knight on d4 with the threat of Bc5. However, in some lines the black queen and king can get into the line of fire on the e-file. 13.Kh1! It's useful 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!

(intending 15...exf5 16.Qd5) with a great position, see Crosa Coll,M - Coelho,L 1-0.

B) 12...Ra7

This wonderful move is the key idea in the Polugaevsky Variation. Black brings their rook into the game via the 7th rank, providing defence and quick counterplay. Of course, this move was discovered by none other than Lev Polugaevsky himself. 13.Qd3! The strongest reply. White has to control the e4 and e3 squares. Their next plan is to play Ne4 hitting Black's queen. 13...Rd7 14.Ne4!.

14...Qe5. This is the main move, Black puts pressure on both knights in the centre. (The rare 14...Qg6?! takes the queen far away from the queenside. 15.Bf3! White protects the knight on e4, making their queen mobile. 15...Bb7 and now after the piece sacrifice 16.Qc3!! Bxe4 17.Rae1!!

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

15.Nf3!.

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

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

Even after the queen trade White's play remains very active. 18...g6 19.c4! Using the hook b5 to opening up the queenside is a common idea, see Pasti,A - Aczel,G 1/2.

B2) 15...Qxb2. Capturing what is often considered a poisoned pawn. This should lead to a clear advantage for White as well, but the latter already has to know the dynamic attacking moves very well. 16.Qe3! Bb7 17.Rab1!.

The queen on b2 is strong, so it's important to deflect it. This is another critical line of the Polugaevsky Variation, with a final branch:

B21) 17...Qxc2 18.Nfg5!!.

A very powerful multipurpose move. The knight protects its colleague on e4 and at the same time 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 pry open the position with 19.Rbc1! Qa4 and now 20.Nxe6!!

winning - all these lines are checked within the game Negi,P - Hermansson,E 1-0.

B22) 17...Qxa2

After this capture, I believe White has two equally good moves giving more than enough compensation for the sacrificed pawns: 18.Nfg5 and 18.Kh1. Both these continuations are thoroughly 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 which can result in a surprise. White must usually sacrifice material in order to attack the black king. I think the most solid way for Black is 15...Qc7 followed by 16...Qa7 to trade queens, though this allows White to open up the queenside with the standard pawn breaks c2-c4 or a2-a4. A typical attacking move for the first player is Nfg5!. From what I have analysed in this article, if White knows all these precise moves and ideas, they will have a much better position out of the opening! :)
