Vienna Game: Hamppe-Meitner Variation — The Trap That Works on Black

Right after 3.Na4, Black's bishop on c5 is under attack. The engine's top choice is Bxf2+ — a check that rips open your kingside. The full engine line runs: Bxf2+ Kxf2 Qh4+ g3. Black gives up a bishop for a pawn and a tempo, hoping to generate an attack against your exposed king. This is the most principled continuation, and the engine confirms it's Black's best try. In practice, though, Black players often avoid this sharp line — and that's where you get an edge. The most popular move in the database is Bb6 (over 5,500 games), which simply retreats the bishop. The engine marks that as an inaccuracy that loses roughly 0.8 pawns of advantage for Black. Your task in the drill is simple: after your opponent doesn't play Bxf2+, punish them.

Looking at the numbers from 23,648 games played from this exact position gives a sobering picture for White. White wins just 46.1% of the time, while Black scores 50.0% — that's a 3.9% gap, plus 3.9% draws. With Stockfish's evaluation at -0.12 (a tiny edge for Black), the theory says this position is essentially equal. But the practical results show that White underperforms compared to the engine's assessment. That means the typical club player doesn't know the right follow-up after 3.Na4. If you learn the key ideas below, you can push your win rate well above that 46.1% average. The drill is designed to teach you the precise responses to each of Black's five most common replies.

Three of Black's popular replies are outright errors according to the engine. Here's what to watch for: Bb6 (played in over 5,500 games) is an inaccuracy that loses about 0.8 pawns. Black preserves the bishop but misses a better chance. d6 (nearly 2,900 games) is also an inaccuracy, losing about 0.6 pawns. Bd4 (over 2,200 games) is a full mistake, costing Black roughly 1.3 pawns. Whenever your opponent plays one of these moves, you've already gained a measurable advantage. The engine's best answer to each of these is Bxf2+ — but Black chose something else. Your job is to take over the game with simple, developing moves that consolidate your edge while keeping an eye on your king's safety. The drill will show you the engine's recommended continuation after each of these suboptimal moves.

The Hamppe-Meitner Variation is ideal for players who want an active, tactical game without memorising 20 moves of theory. Black's best response (Bxf2+) leads to an imbalanced position where you're up a piece for two pawns after Kxf2 — you just need to navigate the queen check on h4. If Black avoids that line, you're simply a tempo or more ahead with a comfortable game. This opening suits aggressive players willing to accept short-term king exposure for long-term material advantage. The drill will let you practice each of Black's five most-played replies until your response is automatic. That 46.1% win rate is waiting to be improved — one drill at a time.
