Trompowsky Attack: Classical Defense with Nf3 – Playing as Black

The Trompowsky Attack starts when White plays 2.Bg5, immediately pinning your knight. By choosing 2...e6 followed by 3...Be7, you've entered the Classical Defense, a flexible and solid setup. Your main idea is straightforward: break the pin and challenge White's centre. You're already threatening to capture the bishop with ...h6 (if White allows it), and you'll soon look to play ...d5 and ...c5, fighting for central space. Unlike some sharper Trompowsky lines, this Classical Defense with Nf3 leads to a more positional struggle. The engine says you are slightly worse by +0.29, so the opening hasn't solved all your problems — but it's a playable, low-risk position where Black can aim for a comfortable middlegame.

From this position White has several options, and knowing how to respond to each will save you time on the clock. Here are the main continuations you'll face: - e3 (by far the most common, 137,145 games): White prepares to develop with Bd3 or Nbd2. You should continue with ...d5, fighting for the centre. White scores only 50.4% here — a balanced result. - Nc3 (40,813 games): White develops the knight. Again, ...d5 is a good response, and Black actually scores better than average — White wins just 46.7% of these games. - Bxf6 (38,440 games): White trades bishop for knight. After ...Bxf6, you have the bishop pair and a clean position. White scores 47.5% — slightly below the draw rate. - c4 (24,089 games): White aims for a Catalan-style setup. Play ...d5 or ...O-O and you're fine. White scores 49.7% — essentially equal. - e4 (9,003 games): This is the mistake we'll cover next. Notice it's the least common of White's main options.

If White plays 4.e4, you've caught them in a clear mistake — the engine says this loses about 1.3 pawns, and the best move instead was Nbd2. After 4.e4, Black should immediately strike back with ...d5, which is part of the engine's recommendation of Nbd2 c5 e4 d5. The position becomes sharp: White has a pawn on e4 and you have one on d5, and your light-squared bishop on c8 suddenly gains scope. Don't be afraid — this is where your homework pays off. While White scores a poor 44.3% from this position (the worst of any option), you can push for an edge if you play actively. The moral: if your opponent rushes to push e4 without preparation, be ready to refute it.

The computer's top choice for White (at depth 16) is 4.Nbd2, which scores a formidable 53.4% for White in practice — the highest win rate of any continuation. After Nbd2, the engine plans to follow up with ...c5, and then White plays e4, reaching a position with ...d5. So you should be ready for this sequence. Black's plan is still the same: get your pawns to d5 and c5, develop your pieces, and castle. The key is not to panic when White plays Nbd2 — it's a strong, patient move, but Black's position is solid. Focus on piece activity and central control, and you'll create counterplay even in the most critical line.
