The Trompowsky Attack (1.d4 Nf6 2.Bg5) pins the knight immediately and forces Black to make an early decision. It's an aggressive alternative to mainline d4 openings with significantly less theory.

Named after Brazilian player Octávio Trompowsky, this opening has been used by elite GMs including Julian Hodgson and Ding Liren. After 2.Bg5, Black must decide: play ...Ne4 attacking the bishop, ...e6 to develop normally, or ...d5 for classical play. Each response leads to distinct positions. The Trompowsky is an excellent practical weapon because it takes Black out of their preparation early.
The Trompowsky Attack is named after Octavio Trompowsky, a Brazilian player who employed 2.Bg5 regularly in the 1930s and 1940s. The opening remained a relatively obscure sideline for decades, occasionally appearing in the games of players who wanted to avoid mainstream d4 theory. It gained significant credibility in the 1980s and 1990s when English GM Julian Hodgson became its leading practitioner, winning numerous brilliancies with aggressive play and demonstrating that the Trompowsky was more than just a surprise weapon. In the modern era, Ding Liren used the Trompowsky at the highest level, including in important tournament games. Magnus Carlsen has also played it occasionally, and its popularity has surged at club level as players seek ways to avoid the enormous body of theory in the Queen's Gambit, Nimzo-Indian, and other mainline 1.d4 systems.
The Trompowsky's strategic idea is to force Black into an early decision about the f6 knight. After 2.Bg5, Black must choose: challenge the bishop with ...Ne4, accept doubled f-pawns after Bxf6, or play quietly with ...d5 or ...e6. Each response leads to structurally distinct positions. If Black plays 2...Ne4, White retreats to f4 or h4 and the game often features a big center for White after d5 and e4. If Black plays 2...d5 3.Bxf6, White gives up the bishop pair but gets a solid center and the potential for a kingside attack. The Trompowsky player should be comfortable with multiple pawn structures since the opening branches early. White often aims for a position with central pawns on d4 and e4 (or d5 and e4), a spatial advantage, and pressure on the kingside. Black's main counterplay involves using the bishop pair (when White takes on f6) or challenging White's center with ...c5 or ...e5 breaks.
The Trompowsky leads to diverse structures depending on Black's response. After 2...Ne4 3.Bf4 c5 4.f3 Nf6 5.d5, White has a Benoni-like structure with a strong d5 pawn. After 2...d5 3.Bxf6 exf6, Black has doubled f-pawns but the bishop pair and semi-open e-file. This structure often leads to strategic battles where Black tries to use the bishops in open positions while White exploits the doubled pawns. After 2...e6 3.e4 h6 4.Bxf6 Qxf6, White has a big center but Black has the two bishops and an active queen. The variety of structures is both a strength and a challenge for Trompowsky players.
In the 2...Ne4 lines, tactical ideas often revolve around White's f3 move and subsequent central expansion. The d5 pawn advance can create tactical threats when supported by e4. Knight jumps to d6 or f5 are common themes once White establishes a big center. In the Bxf6 lines, tactics often arise from the open e-file and Black's attempts to exploit the bishop pair. The Qd2/O-O-O setup can lead to opposite-side castling with mutual attacks. In some lines, White sacrifices a pawn with e5 to open the position for the minor pieces and create kingside threats. The pin on f6 can also create tactical pressure if Black is not careful about the move order.
Julian Hodgson is the Trompowsky's most famous champion, having played it extensively at the GM level for over two decades with excellent results. Ding Liren has used it at the very highest level, bringing new credibility to the opening. Magnus Carlsen employs it occasionally as a surprise weapon. Richard Rapport, known for his creative opening choices, has also played the Trompowsky. At the club level, it has a large following among players who prefer practical positions over heavy memorization.
A model Trompowsky game where Hodgson demonstrated the attacking potential of the opening. White built a large center and launched a kingside attack that Black could not withstand.
Ding Liren showed that the Trompowsky is viable at the absolute top level. His precise handling of the middlegame demonstrated the opening's strategic depth beyond just being a surprise weapon.
The Trompowsky is one of the best openings for players who want a complete 1.d4 system without learning mountains of theory. Start by learning how to handle Black's three main responses: 2...Ne4, 2...d5, and 2...e6. Each leads to a different type of position, so understand the typical pawn structures and plans for each. Julian Hodgson's games are the best starting point for understanding the opening's attacking ideas. The theory is manageable, with most lines requiring only 8-10 moves of preparation. Since the Trompowsky branches early (at move 2!), spaced repetition is particularly useful for remembering the correct response to each Black setup. Openings.gg lets you import a complete Trompowsky repertoire and drill the branching points, which is exactly what you need for an opening where the critical decisions come so early in the game.
Excellent for beginners and club players. It avoids the massive theory of mainline 1.d4 openings and leads to positions where understanding plans matters more than memorization. The ideas are straightforward: develop the bishop early, build a center, and play for a kingside attack. It is one of the most practical opening choices for improving players.
2...d5 is the most solid and popular response, leading to stable positions. 2...Ne4 is the most challenging, directly attacking the bishop and leading to sharp play. 2...e6 is flexible but can allow White a big center. All three are playable, and the choice depends on your style. 2...d5 is recommended if you want a quiet game; 2...Ne4 if you want to fight for the initiative.
Neither is objectively better. The Trompowsky is more forcing and leads to sharper positions since 2.Bg5 directly challenges the knight. The London (2.Bf4 or 2.Nf3 followed by Bf4) is more flexible and solid. The Trompowsky is better for aggressive players who want to create early imbalances, while the London suits those who prefer a reliable, low-risk setup.
Very little compared to mainline openings. You need about 8-10 moves of preparation against each of Black's main responses (2...Ne4, 2...d5, 2...e6). The total amount of theory is a fraction of what the Queen's Gambit or Nimzo-Indian require. This is one of the Trompowsky's biggest practical advantages.
Yes. Ding Liren, Magnus Carlsen, and Richard Rapport have all played it successfully against top opposition. Julian Hodgson proved for decades that it is a legitimate weapon at the GM level. While it is not as deeply analyzed as the Queen's Gambit, the positions it creates are rich and complex enough to provide winning chances at any level.
2...c5 is a less common but playable response, usually leading to a Benoni-like structure after 3.d5. White typically gets a spatial advantage while Black aims for queenside counterplay. The position is less well-analyzed than the main lines, which can be an advantage for the prepared Trompowsky player. Most theory focuses on 2...Ne4, 2...d5, and 2...e6.
