This line of the Vienna Game quickly becomes a fight for the centre. After 4...c6, you've prepared ...d5, challenging White's strong bishop on c4. Your bishop on b4 pins the knight on c3, adding pressure to e4. The position is symmetrical in development but with different plans: White wants to keep their centre and bishop active, while you want to break open the centre with ...d5 and get your pieces into the game. The statistics across 88,738 games tell a remarkably even story: White wins 48.4%, draws 3.8%, and Black wins 47.7%. That's as close to 50/50 as chess gets — a great place to test your understanding of the middle game without worrying about refutations.
The Most Popular Replies and How to Answer Them
Let's look at what White plays most often from this position, and how you should respond. The most-played move is Bd2 (37,293 games, White scores 49.6%). This unpins the knight and prepares to trade bishops — you should respond with ...d5, challenging the centre immediately. Next is a3 (12,110 games, White scores 48.0%), attacking your bishop. Retreat to ...Ba5 or trade on c3 — both are fine. Bg5 (11,535 games, White scores 48.2%) pins your knight to the queen, but as we'll see below, this is actually a mistake. Ne2 (10,204 games, White scores 48.2%) reroutes the knight to g3. Nf3 (9,015 games, White scores 46.2%) develops normally but is also inaccurate. And f4 (5,451 games, White scores 49.2%) tries to attack immediately but weakens White's kingside. Against each of these, your plan is the same: aim for ...d5, develop your pieces, and equalise.
The Engine's Choice: Bb3
The Stockfish evaluation at depth 16 recommends White play Bb3 — retreating the bishop before you can chase it with ...d5. This avoids the pin and keeps the bishop on the a2-g8 diagonal. After Bb3, the engine's suggested line is ...d5 Bd2 dxe4. You get the central break you wanted, and after ...dxe4, the position opens up in your favour. White scores slightly better after Bb3 than after the popular alternatives, but even here, the evaluation remains close to equal. If your opponent plays Bb3, don't worry — just follow up with ...d5 and you're fine.
Three Common Mistakes White Makes
The database reveals three moves that lose White nearly a full pawn compared to the best option. Each is classified as an inaccuracy (losing about 0.8–0.9 pawns). Bg5 is the first: it pins your knight but leaves White's bishop vulnerable and doesn't address the coming ...d5 break. Nf3 develops a piece but ignores the central tension — you can punish it by playing ...d5 immediately. f4 is the most aggressive mistake: it tries to open the f-file but weakens White's king and does nothing to stop ...d5. In all three cases, your response is the same: push ...d5, open the centre, and enjoy the better chances. If you see any of these moves from your opponent, you've already won the opening.
