Trompowsky Attack
1.d4 Nf6 2.Bg5
The Trompowsky Attack — 1.d4 followed by 2.Bg5, whatever Black does — sidesteps the entire mainstream of 1.d4 theory on move two. You get a solid, positionally rich game with surprise value that lasts: Nimzo, King's Indian and Grunfeld specialists all find their preparation useless.

Trompowsky: 2...Ne4 3.Bf4 Main Line
1.d4 Nf6 2.Bg5 Ne4 3.Bf4 c5 4.f3 Qa5+ 5.c3 Nf6 6.d5
The most tested line. Black kicks the bishop, White keeps it with 3.Bf4 and then challenges the knight with f3. The check on a5 is Black's main resource; after c3 and d5 White has grabbed space and the position becomes an unusual Benoni where Black's queen is misplaced on a5.
Trompowsky: 2...e6 Modern Attack
1.d4 Nf6 2.Bg5 e6 3.e4 h6 4.Bxf6 Qxf6 5.Nf3
White grabs the full centre with e4 and happily trades the bishop for the knight. The resulting position is a big-centre versus bishop-pair race: if White consolidates with c3, Bd3 and O-O, the space advantage tells; if Black opens the game with ...d5 or ...c5 at the right moment, the two bishops speak.
Trompowsky: 2...d5 Classical Reply
1.d4 Nf6 2.Bg5 d5 3.Bxf6 exf6 4.e3 Bd6 5.c4
Black accepts doubled f-pawns in return for the bishop pair and a half-open e-file. This is the most solid answer and the one you must be ready for. White plays against the structure with c4, Nc3 and Qb3, aiming at d5 and b7 while keeping the position closed enough that the bishops cannot breathe.
Trompowsky: Vaganian Gambit (2...c5)
1.d4 Nf6 2.Bg5 c5 3.d5 Qb6 4.Nc3 Qxb2 5.Bd2 Qb6
Black snatches the b2-pawn and White gets a development lead plus the open b-file. The critical moment is whether Black's queen can retreat in time; every tempo White gains chasing her is a piece brought into the attack. Sharp, forcing and very much worth knowing before you meet it over the board.
Trompowsky: 3.h4 Aggressive Line
1.d4 Nf6 2.Bg5 Ne4 3.h4 c5 4.d5 Qb6 5.Nd2
Instead of retreating, White offers the bishop and gains time on the h-file. The idea is thoroughly modern: the rook's pawn is a piece in the attack, and Black's knight on e4 turns out to be a target rather than a strength. Requires precise play from both sides and is a nightmare for the unprepared.
Trompowsky: 2...g6 Fianchetto Answer
1.d4 Nf6 2.Bg5 g6 3.Bxf6 exf6 4.e3 d5 5.c4
King's Indian and Grünfeld players often meet the Trompowsky this way and get the structure wrong. After Bxf6 the fianchetto plan loses much of its point, because the bishop that was supposed to dominate the long diagonal now stares at its own pawn on f6. White plays c4 and a normal, comfortable game.
Key ideas
- Play 2.Bg5 against everything: one system replaces a library of main-line theory.
- Meet 2...Ne4 with 3.Bf4 — the bishop keeps its influence and Black's knight must justify its travels.
- Double Black's f-pawns with Bxf6 when it favors you: a structural edge that lasts into the endgame.
- Keep the surprise working: most Black players face the Trompowsky a few times a year, you play it weekly.
Typical plans and structures
Against the critical 2...Ne4 3.Bf4 c5, White grabs the center with f3 and d5 — the main line where the course invests its deepest work. Against 2...e6 or 2...d5, White chooses between Bxf6 structures (doubled pawns, then a slow squeeze with e3, c4 and long-term pressure) and flexible setups with e3 and Nd2. The recurring trumps: an unbalanced structure Black rarely knows, the two-bishop trades on White's terms, and middlegame plans you have rehearsed and your opponent is improvising.
Who should play it
1.d4 players who want a complete, low-maintenance repertoire weapon with genuine bite — ideal if you would rather understand one system deeply than memorize five defenses' main lines.

Frequently asked questions
What exactly defines the Trompowsky Attack?
The position after 1.d4 with 2.Bg5 — played whether Black responds 1...Nf6 (the pure Trompowsky) or 1...d5 (the related Pseudo-Trompowsky/Hopton). The defining idea is the immediate queen's-bishop sortie before Black's setup gets a say.
Is the Trompowsky sound or just a surprise weapon?
Both: it is theoretically respectable — used by elite players from Julian Hodgson to Magnus Carlsen, and famously by Vladimir Kramnik — while ALSO carrying surprise value, because most Black repertoires give it a fraction of the attention the main lines get.
What is Black's most critical answer?
2...Ne4, hitting the bishop immediately, followed by ...c5 — met by 3.Bf4 and the ambitious f3 and d5 center. That tabiya is the theoretical heart of the Trompowsky and the centerpiece of this course's repertoire.
