Vienna Game: Stanley Variation with Bb4 — A Complete Guide for White
After 1.e4 e5 2.Nc3 Nf6 3.Bc4 Bb4, you've reached the Stanley Variation of the Vienna Game. White's fourth move, 4.Nf3, develops naturally and leads to a position that is remarkably balanced. Across over a million games in the Lichess database, White scores 50.9% — almost exactly half. The engine agrees: Stockfish evaluates this at -0.04, a dead-level position with neither side holding an edge. That means you are starting from a perfectly fair fight. The question is: can you navigate it better than your opponent? The drill below will help you practice the critical moment: what to do after Black captures on c3.

By far the most popular move in this position is Bxc3, played over 507,000 times — roughly half of all games. Black trades their bishop for your knight on c3, doubling your c-pawns. This is the engine's top recommendation as well. After you recapture with bxc3, Black continues with ...d6, and the engine suggests you reply with Be3. Why Be3? It develops the bishop to a useful square, guarding the d4 pawn and preparing to castle kingside. You now have the bishop pair and an open b-file to work with later. The position remains roughly equal, but your two bishops can become a real force in the middlegame, especially if the centre opens up.
Black's Most Dangerous Alternative: Castling
The second most common Black reply is O-O (167,000 games), giving you a different test. Here Black ignores the tension on c3 and simply gets their king to safety. White scores just 49.6% against this move, so it's nothing to fear — but you need a plan. A natural continuation is to castle yourself and maintain the pressure. Your bishop on c4 eyes the f7 square, your knight on f3 controls the centre, and you still have the option to push d4 or prepare an attack on the kingside. Don't rush to capture on c3 yourself; Black might retreat the bishop to c5 or a5, and you'd rather keep the tension.
The Statistics That Matter
The numbers tell a clear story about which Black moves give you the best chance. Against the obscure move h6 (played just 21,000 times), White scores a whopping 56.0%. That's because h6 is a genuine mistake — the engine says it loses about 1.3 pawns compared to the correct Bxc3. What's your punishment? Simply continue developing: 5.d4 exd4 6.Nxd4 and you'll have a comfortable edge. Similarly, c6 is an inaccuracy that loses roughly 0.8 pawns. Both of these moves neglect the central tension, and you can seize the initiative by striking back in the centre.
The Typical Middlegame You're Aiming For
When Black plays the best move (Bxc3) and you recapture with the b-pawn, you're steering toward a specific type of middlegame. You'll have doubled c-pawns, but also the bishop pair and a half-open b-file. Your pawn structure means you should be alert for play on the queenside — sometimes a well-timed c4 break can open lines for your bishops. Meanwhile, your king is safest on the kingside after castling. The engine line 5.bxc3 d6 6.Be3 gives you a solid, harmonious setup. From there, play can revolve around controlling d4, deciding when to push e5, and using your bishop pair to outmanoeuvre Black's knight-and-bishop army.

Frequently asked questions
Is the Vienna Game Stanley Variation good for White?
Yes, it's perfectly fine for White. The position after 4.Nf3 is dead level according to Stockfish (-0.04), and White scores 50.9% across over a million games. You're not gaining an advantage from the opening, but you're not at risk either — it leads to rich, playable chess.
What is the best move for Black in the Stanley Variation?
The engine recommends Bxc3, which is also the most common move in practice. Black trades their bishop for your knight, doubling your c-pawns. White then recaptures with bxc3 and continues with d6, followed by Be3 to complete development.
How do I punish h6 or c6 as White?
Both are mistakes. Against h6 (which loses about 1.3 pawns), you can play 5.d4 exd4 6.Nxd4 and enjoy a clear edge. Against c6 (an inaccuracy losing ~0.8 pawns), you again look to seize the centre. White scores 56.0% against h6 and 50.2% against c6, so these moves are gifts.
Should I capture on c3 if Black doesn't take first?
Not necessarily. If Black plays O-O, Nc6, or d6, there's no rush to take on c3. Your knight is actively placed, and you can continue developing — castling, playing d4, or repositioning your pieces. Only capture if it gives you a concrete benefit.
