The Trompowsky Attack (1.d4 Nf6 2.Bg5) is a sharp way to avoid the main lines of the Queen's Pawn Game. When Black answers with 2...c6, you have a choice — and 3.Nd2 is a solid, flexible development that keeps the tension in the centre. The resulting position is dead level: Stockfish gives it +0.14, a tiny edge for White that's basically equal. Over 1,224 games, White scores a healthy 50.3% (with just 4.1% draws), so you can expect a fight. The interactive drill below will show you the key moment after 3.Nd2 — it's Black's turn, and how they handle the coming pawn break to d5 will shape the whole game.

Find your own #1 mistake — free →Why 3.Nd2? The Quiet but Tricky Setup
After 1.d4 Nf6 2.Bg5 c6, you have left the beaten path of the main Trompowsky (which often sees 2...Ne4 or 2...d5). Black's ...c6 aims to support ...d5 and create a solid centre, but it also weakens the b6-square and gives your queen's knight a natural home on d2. By playing 3.Nd2, you avoid the pinning ...Bg4 ideas that can arise after 3.Nc3, and you keep your c-pawn free to advance later. The knight on d2 is ready to hop to f1 or even b3 if needed, but its main job is to support the next move — d5 — which the engine rates as the best continuation. You're not rushing; you're asking Black to declare their intentions first.
The Engine's Plan: d5 and a Harmonious Setup
Stockfish's top line after 3.Nd2 is d5, followed by e3, Bf5, and Ngf3. Let's unpack that: you push your d-pawn to d5, gaining space and kicking Black's knight. Black will likely capture with ...cxd5, and you recapture ... but with which piece? The engine wants e3 first, developing the bishop and keeping the e4-square solid, then Bf5 puts pressure on the queenside light squares. Finally Ngf3 brings your other knight into play. This setup is rock-solid: you control the centre, your pieces are active, and Black has to work for equality. Against weaker opposition, that slight +0.14 edge can feel much bigger.
What the Numbers Say: Black's Most Popular Replies
In practice, Black has tried several moves here. Here's how White scores against each of the main options, based on over 1,200 games: - d5 (472 games, White scores 50.6%): The most common reply and the engine's favourite. Black challenges the centre head-on — expect a symmetrical pawn structure and a slow manoeuvring game. - Qa5 (171 games, White scores 48.0%): An active queen sortie. Black pins your bishop and eyes the a4-square. White scores just under half, so be careful — keep developing and don't let the queen cause trouble. - e6 (156 games, White scores 51.9%): This is actually an inaccuracy that costs Black about 0.8 pawns. The engine says Black should have played d5 instead. Punish it by occupying the centre with d5 yourself. - d6 (120 games, White scores 46.7%): A passive but solid setup. You have the edge — just keep developing with e3, Bf3/Be2, and 0-0. - Qb6 (90 games, White scores 45.6%): Another queen move attacking the b2-pawn. Your best response is to ignore the pawn and play d5, gaining space. - h6 (88 games, White scores 53.4%): Black asks what your bishop is doing. Retreat to h4, f4, or exchange — your highest-scoring line. Keep it simple.
Spotting the Mistake: Punishing ...e6
If Black plays 3...e6, you have a clear opportunity. The statistics show it's an inaccuracy, and the engine says it costs Black roughly 0.8 pawns of advantage. Why? Because ...e6 blocks Black's light-squared bishop and doesn't challenge your control of d5 at all. Your plan is straightforward: 4.d5! Push immediately, opening up the centre while Black's pieces are still cramped. After 4...exd5 (or 4...cxd5, both are fine for you), you recapture and enjoy a space advantage. Black's bishop on c8 is stuck behind the pawn chain, and your knights can find great squares. Many club players don't realise how serious this inaccuracy is — in the drill below, if Black chooses ...e6, the engine will show you exactly how to capitalise.

Frequently asked questions
What is the Trompowsky Attack?
The Trompowsky Attack (1.d4 Nf6 2.Bg5) is an opening where White immediately puts pressure on Black's knight, inviting Black to break the pin with ...Ne4 or ...h6. It's a flexible, aggressive system popularised by Brazilian GM Octávio Trompowsky and now used by many club players to avoid heavy theory of the Queen's Gambit or Indian Defences.
Is 3.Nd2 a good move against ...c6?
Yes, 3.Nd2 is a solid and flexible choice. It avoids the pin ...Bg4 that can harass a knight on c3, keeps the c-pawn free for later advance, and supports the central push d5. The engine evaluates the position as dead level (+0.14), and White scores just over 50% in practice. It's a great option for players who want a playable middlegame without memorising long theory lines.
How should White punish 3...e6 in the Trompowsky c6 variation?
The engine identifies 3...e6 as an inaccuracy that costs Black about 0.8 pawns. White should immediately play 4.d5, opening the centre while Black's light-squared bishop is still locked in on c8. After the exchange of pawns, White enjoys a space advantage and better piece activity. This is the key moment where you can grab a tangible edge.
What is White's best plan after 3.Nd2 d5?
After 3...d5 (Black's most common reply), the engine recommends building a harmonious setup with e3, Bf5 (or Be2 and Bf3), and Ngf3. You want to complete development, castle kingside, and then decide whether to aim for a minority attack on the queenside or central play. The position is balanced, so look for small advantages — better piece placement, control of key squares, and keeping your pawn structure healthy.
