The Center Game: von der Lasa Gambit with 3...Nf6

After 4.Qxd4 the centre is already liquidated, so the opening has turned into a battle of development and piece activity. Your queen sits in the middle, which is both a strength and a target. Black's most dangerous idea is to chase it with 4...Nc6 — the engine's first choice and by far the most popular move (158,628 games). From there you will retreat with 5.Qe3, and Black replies 5...Bb4+, forcing 6.c3. The resulting position is solid for you but requires careful play. Your core mission in this opening is to keep your development flowing while your opponent tries to exploit the queen's early exposure. If you can navigate those few tricky moments, the Center Game can lead to lively, attacking middlegames where your bishop on c4 and active queen become real assets.

The computer says Black's best move here is 4...Nc6, hitting your queen immediately. After 5.Qe3 Bb4+ 6.c3, Black has forced you to spend a tempo on c3, but you have kept your bishop pair and retained a playable position. This line is the main test of the von der Lasa Gambit. If your opponent knows it well, you will not get a free lunch — but you also will not be worse by much. The real opportunities come when Black chooses something else.

Many Black players assume they can develop more quietly — and the statistics show that three common moves are genuine errors that give you an edge. Here is what to look for: - 4...d6 (18,882 games): This is an inaccuracy that costs Black roughly 83 centipawns compared to the best move. Black blocks their own bishop and wastes a tempo. White scores 46.3% — already better than the overall average. - 4...Be7 (10,248 games): A mistake costing roughly 109 centipawns. Black develops but ignores the pressure on your queen. White scores 49.0% here. - 4...c5 (10,710 games): A mistake costing about 128 centipawns. Black tries to attack your queen with tempo, but the c-pawn push weakens the d5-square and leaves Black's king vulnerable. White scores 48.6%. When you face any of these, trust that you are already standing a bit better. Keep developing naturally and let the position's dynamics work for you.

A move that might look odd — 4...b6 — actually gives White your best winning chances of any popular reply. It has been played 6,037 times, and White scores a strong 53.0% from that position. Black intends to fianchetto the light-squared bishop on b7, but they are falling behind in development and leaving the queen on d4 unchallenged. If you face 4...b6, do not overcomplicate it: play simple, solid moves, and you will likely outplay your opponent in the early middlegame.
