Trompowsky Attack: The Complete Guide
The Trompowsky Attack (the Trompowsky Opening) — its main lines, the plans for both sides, and how to tell whether it fits your style.
Starting position and moves
The Trompowsky Attack (also known as the Trompowsky Opening) is an opening for White, classified under ECO codes A45. It begins with:
The idea behind the Trompowsky Attack
White pins or provokes the f6-knight immediately, sidestepping the entire theory of the Nimzo-Indian, Queen's Indian, and King's Indian in one move. If Black takes on g5, White recaptures with the pawn (or reroutes the queen) to build an unusual but sturdy structure with attacking chances down the semi-open g- or e-file. It is a favorite try for players who want a distinct, low-theory repertoire against 1...Nf6.
Main lines and key variations
| Variation | Moves |
|---|---|
| Main Line (2...Ne4) | 1.d4 Nf6 2.Bg5 Ne4 3.Bf4 c5 4.f3 Qa5+ 5.c3 Nf6 |
| Raptor Variation | 1.d4 Nf6 2.Bg5 Ne4 3.h4 |
| Poisoned Pawn (...Qb6) | 1.d4 Nf6 2.Bg5 Ne4 3.Bf4 c5 4.f3 Qb6 |
| 2...d5 (Queen's Gambit-like) | 1.d4 Nf6 2.Bg5 d5 3.Bxf6 exf6 |
Main Line (2...Ne4): Black kicks the bishop with a knight jump to e4; White retreats to f4 and builds a solid centre with f3/c3, often gaining the bishop pair advantage later.
Raptor Variation: A sharp, provocative try where White advances the h-pawn immediately rather than retreating the bishop, aiming for quick kingside expansion.
Poisoned Pawn (...Qb6): Black grabs at b2 and d4 with an early queen sortie instead of the quieter ...Qa5+; White must choose between defending b2 passively or counterattacking with c3 and Qc1, letting Black take the pawn.
2...d5 (Queen's Gambit-like): Black declines the pin fight and takes a Queen's Gambit Declined-style centre; White doubles Black's f-pawns for a long-term structural target.
Plans for both sides
White's plans
- Provoke structural weaknesses by trading the g5-bishop for the f6-knight at the right moment.
- Build a broad pawn centre with c4/e4 while Black is still untangling from the pin.
- Use the semi-open g-file or e-file for a kingside attack once castled.
Black's plans
- Challenge the bishop immediately with ...Ne4 to gain time and disrupt White's plan.
- Accept doubled pawns in some lines in exchange for the bishop pair and open lines.
- Play a solid ...d5 or ...c5 central response to sidestep the sharpest tactics.
Typical pawn structure
Highly flexible and move-order dependent — the Trompowsky can lead to doubled Black f-pawns and open lines, a Queen's Gambit-style centre, or a sharp knight-versus-bishop skirmish on e4/g5. There is no single defining pawn skeleton; the opening's identity comes from White's early bishop sortie rather than a fixed structure.
Famous practitioners
The Trompowsky Attack has been championed by Julian Hodgson, Peter Wells, Wesley So (as an occasional weapon). Hodgson–Rausis, Wijk aan Zee 1993: One of Julian Hodgson's many demonstration games with the line he did more than anyone to popularize at grandmaster level in the 1980s-90s.
Strengths and weaknesses
Who should play the Trompowsky Attack?
1.d4 players who want to dodge the vast theory of the Nimzo-Indian and King's Indian complexes with a single flexible move. Well suited to club and improving players who prefer understanding a handful of typical structures over memorizing forcing lines.

Frequently Asked Questions
Is the Trompowsky Attack good for beginners?
Yes — it is one of the lowest-theory ways to meet 1...Nf6 while still posing real problems. Rather than memorizing deep Nimzo-Indian or King's Indian theory, White learns a handful of recurring structural ideas (doubled f-pawns, the bishop pair, quick central expansion) that transfer across many games.
What happens if Black just takes the Trompowsky bishop with 2...Ne4?
3.Bf4 is the standard retreat, keeping the bishop active on the a7-g1 diagonal and preparing c3/f3 to support the centre. White often ends up with the bishop pair and a comfortable position after Black's knight relocates back to f6 or d6.
Who popularized the Trompowsky Attack?
English grandmaster Julian Hodgson is most associated with bringing the line to prominence in the 1980s and 1990s, scoring many wins with it at strong international level and inspiring a generation of players to adopt it as a practical weapon against 1...Nf6.
