Trompowsky Attack

Key ideas for both sides

Plans and pawn structure

The Trompowsky is about the f6 knight. If White takes it, Black gets the bishop pair and White gets the better pawns, and White then builds the center with c4 and Nc3 or with e3 and a bishop on d3. If Black jumps to e4 first, White chases the knight with f3 or supports the bishop with h4, and the game turns sharp. Black's plans revolve around activity: open lines for the bishops, strike with ...c5 or ...d5, and use the queen against the b2 pawn that the bishop left behind.

What the Trompowsky Attack is about

The Trompowsky Attack begins 1.d4 Nf6 2.Bg5. White develops the c1 bishop at once and threatens Bxf6, which would leave Black with doubled pawns. It is a direct way to avoid the long theory of the Indian defenses, because Black has to deal with a concrete problem on move two.

In 6637 games White scored 52.1%. The engine sees 2...c6, 2...d5 and 2...h6 as Black's best moves, all of them close to equal. In each of the top lines White does take on f6, so Black should be ready for the bishop-pair structures that follow.

The main variations

The Classical Defense, 2...e6, is the most played reply, with 1713 games and White scoring 52.4%. Black prepares to recapture on f6 with the queen, so a trade does not hurt the pawns. The most popular follow-up is the Big Center Variation, 3.e4, where White uses the pin to grab space with both center pawns.

The Edge Variation, 2...Ne4 3.Bh4, keeps the bishop on the h4-d8 diagonal. The knight on e4 is active and the engine prefers Black slightly. White often follows with f3 to drive the knight back.

The Raptor Variation, 2...Ne4 3.h4, is the sharp try. White leaves the bishop on g5 and protects it with the h-pawn, so if Black takes the bishop, White's h-file opens. White scored 52.7% in 223 games.

The engine's top choices are quieter. After 2...c6 3.Bxf6 exf6 4.c4 d5 5.cxd5 Qxd5 6.Nc3, Black has the bishop pair and an active queen. After 2...d5 3.e3 c5 4.Bxf6 gxf6 5.dxc5 Nc6 6.a3, White has won a pawn for the moment, but Black has central control and open lines. 2...h6 3.Bxf6 exf6 forces the decision at once and leads to similar bishop-pair positions.

Typical plans for White

White's choices start with the bishop. Take on f6 when Black's recapture damages the pawns, and then build the center. Against doubled f-pawns, c4 and Nc3 or e3 and a bishop on d3 are the standard setups, and White's pieces aim at the light squares Black can no longer cover with pawns.

• Against ...Ne4. Retreat to f4 or h4 and challenge the knight with f3, or go for the Raptor with h4.
• Against ...e6. The e4 push gains space while the pin holds. If Black breaks the pin, White keeps a broad center.
• Cover b2. With the bishop gone from c1, b2 is loose. Nc3, Qc1 or a well-timed Bxf6 keep it safe.

In the bishop-pair structures, keep the position closed for as long as you can. Black's bishops need open lines, and every move that keeps them shut helps White.

Typical plans for Black

Black's first decision is about structure. With ...e6, a trade on f6 is met by the queen and Black's pawns stay intact. With ...c6, ...d5 or ...h6, Black accepts doubled pawns or an e-pawn recapture and gets the bishop pair in return.

After the trade, Black should open the position. Pawn breaks with ...c5 or ...f5 give the bishops lines, and a queen on b6 or d5 often hits b2 and the center at once. The engine's line with 2...c6 shows this: the queen recaptures on d5 and stands well.

• After ...Ne4, keep the knight active and be ready to meet f3 with a retreat to f6 or d6.
• Do not let White play e4 for free while the pin is still on.
• Castle where your pawns are healthy. After gxf6, the kingside is often not the right home.

Mistakes club players make

• Grabbing b2 without care. A queen on b2 can be chased while White develops with tempo. Check the follow-up before taking.
• Retreating the bishop again and again. White players who move the bishop four times fall behind in development. Decide early whether to trade on f6.
• Black ignoring the pin. In the ...e6 lines, a careless setup lets White play e4 and e5 with tempo.
• Passive play with the bishop pair. Two bishops need open lines. Keeping the center closed hands White the better structure for nothing.
• Taking on g5 in the Raptor without a plan. The open h-file can give White a fast attack.

Who should play it

The Trompowsky suits White players who want to avoid the main theory of the Indian defenses and get an unbalanced position early. It needs little memory work but a good feel for pawn structures, since most games turn on the bishop pair against better pawns.

For Black, it is a fair fight. Players who like the bishop pair should welcome ...c6 or ...h6 lines, while those who want a normal structure can choose 2...e6.

How to play against it

As Black, decide in advance how you feel about doubled pawns. If you dislike them, play ...e6 so you can recapture on f6 with the queen, or jump to e4. If you accept them, ...c6 or ...h6 followed by the e-pawn recapture gives you the bishop pair. Keep the b2 pawn in mind; it is often the first target.
