The Trompowsky Attack is what you get after 1.d4 Nf6 2.Bg5 — and it’s one of the cheekiest second moves in all of chess. Instead of letting Black wheel out the Nimzo-Indian, the King’s Indian, or the Grünfeld (three giant bodies of theory White would normally have to wade through), White just pokes the f6-knight on move two. The message is blunt: “Do something about that knight, or I’ll swap it off and wreck your pawns.” It’s a low-theory, flexible, slightly annoying surprise weapon — the kind of opening that makes a well-prepared opponent’s careful homework completely useless.
The 30-second version
- Moves: 1.d4 Nf6 2.Bg5 · ECO: A45 · You play it as: White.
- The idea: attack the f6-knight at once; if Black isn’t careful, Bxf6 doubles Black’s pawns. Sidesteps the Nimzo, KID and Grünfeld entirely.
- Why people love it: almost no forced theory to memorize, and it drags booked-up opponents into unfamiliar territory.
- Best for: d4 players who want a sound, practical surprise weapon and hate memorizing 25 moves of mainline prep.

The Trompowsky's most common line: 2...Ne4 hits the bishop, White retreats to f4, and a flexible, low-theory middlegame begins.
What’s the big idea behind the Trompowsky?
Most 1.d4 games go 1.d4 Nf6 2.c4 (or 2.Nf3) and then White braces for whichever huge defense Black has prepared. The Trompowsky says: no thanks. By playing 2.Bg5, White develops a piece and immediately attacks the f6-knight, threatening to take it.
Why does that matter so much? Because the f6-knight is Black’s most natural developing piece, and if White ever plays Bxf6, Black has to recapture with a pawn — either …gxf6 (busting up the kingside) or …exf6 (handing White a long-term structural target). So Black has to spend a move doing something about the threat, and that’s where all the Trompowsky’s lines come from. White, meanwhile, has dodged the entire mainline theory tree in a single move. That’s the whole appeal: maximum disruption for minimum memorization.
What are the main lines?
Unlike a rigid “system,” the Trompowsky branches based on how Black answers the threat to f6. Here are the big four — we go deeper on the variations page.
2…Ne4 — the most common reply
Black shoves the knight forward to e4, hitting the g5-bishop and gaining a tempo. White simply retreats — usually 3.Bf4 (the main move, keeping the bishop active) or 3.Bh4. It looks like Black got a free tempo, but that advanced knight can become a target, and White is happy to chip at it with f3 later.
2…e6 — solid, and inviting the sharp 3.e4
Black supports a future …d5 and frees the f8-bishop. White’s most ambitious reply is the sharp 3.e4!?, grabbing a big center. After 3…h6 4.Bxf6 Qxf6 5.Nc3, White has a broad pawn center and a lead in development — double-edged and fun.
2…c5 — striking the center, accepting doubled pawns
Black hits d4 immediately. White’s thematic answer is 3.Bxf6 (doubling Black’s pawns) 3…gxf6 (or …exf6) 4.d5!, grabbing space and clamping the position. Black gets the bishop pair and open lines in return — a genuine fight.
2…d5 — the quiet, solid approach
Black just builds a normal pawn center. White can still play 3.Bxf6 exf6 (or …gxf6) and steer toward a comfortable, slightly better structure, or keep pieces on with 3.e3. Calm and reliable for both sides.
What are the plans for both sides?
For White:
- Decide early whether to grab structure with Bxf6 (doubling Black’s pawns) or keep the bishop and develop with e3, c4 (or c3), Nc3, and sometimes e4.
- Use the time Black spends reacting to f6 to grab a central or space advantage — d5 clamps, e4 expands.
- Aim your pieces at the weaknesses you created: those doubled black pawns won’t run away.
For Black:
- Don’t panic about the doubled pawns — they often come with the bishop pair and open files as compensation.
- Hit the center fast with …c5 and …d5, and develop actively.
- After 2…Ne4, be ready to support or reposition the knight rather than leave it stranded.
Strengths and weaknesses
Why you’ll love it:
- Tiny theory burden. You learn a handful of plans, not a forest of forcing lines.
- It dodges everything. No Nimzo-Indian, no King’s Indian, no Grünfeld — all sidestepped on move two.
- It’s annoying to face. Opponents leave their prep behind and have to think from move three.
The catch:
- It’s not objectively better than the mainlines. With accurate play Black equalizes comfortably.
- Giving up the bishop pair with Bxf6 is a real concession — you’re betting structure beats bishops.
- Strong, well-prepared opponents know the antidotes, so the surprise value fades at the top.
Who plays the Trompowsky?
Its greatest champion is English grandmaster Julian Hodgson, who used it for years as a main weapon and scored brilliantly with it, turning a sideline into a respected attacking try. Former Women’s World Champion Antoaneta Stefanova has wielded it too, and even Magnus Carlsen has wheeled it out to dodge preparation at the elite level. When the world champion reaches for your “offbeat” opening to avoid an opponent’s homework, you know it has real practical teeth.
A fun bit of history
The opening is named after the Brazilian champion Octávio Trompowsky, who played 2.Bg5 in the 1930s and ’40s. For decades it lived in the shadows as a curiosity. Then a wave of English attacking players — Hodgson above all — adopted it in the 1980s and ’90s and proved it could be a genuine fighting weapon, not just a quick-draw dodge. (You’ll sometimes see it called the “Tromp” for short.) Today it’s a beloved club-level surprise and a regular guest even in grandmaster games whenever someone wants to sidestep a wall of preparation.
Is the Trompowsky right for you?
If you’re a d4 player tired of memorizing mainline theory, the Trompowsky is a dream — one cheeky move and you’re in your own world. If you love practical, unbalanced positions where understanding beats memorization, you’ll feel right at home. If you specifically want to fight for a big theoretical advantage every game, the Tromp will feel a little modest — it gets a sound, playable game, not a refutation.

FAQ
Is the Trompowsky Attack good for beginners? It’s a solid, low-theory choice — you learn plans instead of memorizing lines. The one thing to grasp early is why Bxf6 (doubling Black’s pawns) is the point. See the beginner’s guide.
Is the Trompowsky for White or Black? It’s a White opening — White chooses it with 1.d4 Nf6 2.Bg5. Black just picks how to meet the threat to f6.
Does the Trompowsky avoid the Sicilian/Nimzo/King’s Indian? It can’t avoid the Sicilian (that’s a 1.e4 thing), but as a 1.d4 weapon it neatly sidesteps the Nimzo-Indian, King’s Indian, and Grünfeld in one move.
Can the Trompowsky be beaten? It can’t be “refuted” — it’s sound — but Black equalizes comfortably with accurate play, usually via 2…Ne4, 2…e6 or 2…d5. See how to beat the Trompowsky.
Why play 2.Bg5 instead of a mainline? To dodge huge bodies of theory and drag the opponent into an unfamiliar, practical fight. It’s a surprise-and-disrupt weapon, not a bid for a forced advantage.
