Van Geet Opening: Pfeiffer Gambit — Black's Repertoire Guide
The Van Geet Opening (1.Nc3) is an offbeat way for White to dodge mainline theory, and the Pfeiffer Gambit (2.f4) turns it into a sharp fight. After 1.Nc3 d5 2.f4 d4 3.Ne4 e5, you have already sidestepped every passive line — Black is actively fighting for the centre. The engine rates this position at -0.15, which is basically dead level: neither side is better out of the opening. With Black winning 52.4% of the 191 games in the database, you are the one with the higher score. The drill below lets you practise the critical reply to whatever White tries next.

By playing 3...e5, you challenge White's knight on e4 immediately. You are saying: 'You pushed your knight forward early — now it better have a good square to go to.' Black's pawn on d4 already cramps the knight's retreat, and 3...e5 attacks it again while opening lines for your own pieces. If White captures on e5, you recapture with the knight (Nxe5) and develop naturally to c6. If White flinches with a move like d3, you will have gained time and space. Statistically, Black scores over 52% from this position — not dominant, but clearly the side with the plus.
White's Best Move: fxe5
The engine says the only move that keeps the game level for White is 4.fxe5, which has been played in 106 of the 191 games. The sequence goes 4.fxe5 Nc6 5.c3 Nxe5, and Black is perfectly fine. Your knight lands on e5 with tempo, targeting White's pawn on c3 and eyeing light squares. From here, Black can develop naturally with d6, Be6, Nf6, and castle kingside. White scores just 42.5% in this line — you are already pressing. Memorise this one sequence so that when White plays the best move, you are ready.
Punishing White's Inaccuracies
White will often try something else, and the engine says most alternatives are outright inaccuracies or mistakes. The three most common errors are: d3 (played 33 times, loses ~0.9 pawns), Nf3 (14 times, loses ~0.7 pawns), and g3 (5 times, loses ~1.2 pawns). Against d3 or g3, Black can simply take on f4 and keep the extra pawn — White's compensation is an illusion. Against Nf3, Black can push ...e4, kicking the knight and keeping the pawn. In all of these, you should be aiming to take the f4 pawn and then consolidate with natural development (Nc6, Bg4 or Bf5, Nf6, and castling).
What About The Other Moves?
White has a few other tries that the database mentions. e3 (19 games) scores 52.6% for White, which might look scary, but that line often transposes into a French Defence-ish structure where White is playing with an exposed knight on e4. Nf2 (only 3 games) scores 66.7% for White, but you should never fear tiny-sample statistics. If White plays e3, your simplest approach is to develop naturally: Nc6, Nf6, Bb4+ (or Be7), and castle. The knight on e4 is unstable; you can kick it with ...f5 whenever you want. Trust the position – Black's central pawn duo and lead in development are real assets.

Frequently asked questions
Is the Pfeiffer Gambit sound for White?
According to the engine, the position after 3...e5 is dead level at -0.15. That means White is not better — but they are also not losing. The gambit is perfectly playable for both sides at club level. Black's practical results are slightly better (52.4% wins).
What should I do if White plays 4.d3?
The engine labels 4.d3 an inaccuracy that loses ~0.9 pawns. Black should simply capture the free pawn on f4 with 4...exf4. White's knight on e4 is awkward, and Black can follow up with Nc6, Bb4+, and consolidate the extra pawn.
How do I play after 4.fxe5 Nc6 5.c3?
Recapture with 5...Nxe5. From there, continue developing with d6, Be6, Nf6, and castle kingside. Your knight on e5 is well placed — White's c3 pawn is a target, and you have easy natural development.
