The Van Geet Opening: Hulsemann Gambit — Playing for Black

The Hulsemann Gambit (1.Nc3 e5 2.e3 d5 3.Qh5) is an offbeat attempt to catch you off guard. White develops the queen early, hoping you'll panic or blunder. By playing 3...Be6, you've kept your cool: you defend the e5-pawn, develop a piece, and avoid traps. Your main long-term goals are simple. First, finish developing your kingside — get the knight to f6, castle, and let White's queen become a target. Second, don't let White's early queen activity turn into real pressure. The engine says you are slightly worse, but that advantage is fragile. If White doesn't know what to do next, you'll equalise quickly. In fact, many of White's alternatives to the best move are clear mistakes you can punish.

The engine's best move is 4.Qxe5 — White grabs the pawn and forces you into action. The top continuation runs 4.Qxe5 a6 5.Nce2 Nc6, and now White's queen has to retreat while you gain time with development. The move 4...a6 is a cool-headed response: it prevents any ...Bb5 ideas and asks White to show their hand. Then 5.Nce2 gets the knight out of the way of the c-pawn, and 5...Nc6 attacks the queen, forcing it to move again. You'll have given up one pawn, but you're ahead in development with two pieces already out and more coming. If you prefer, you can also consider 4.Qxe5 Nc6 directly — either way, you're betting that your activity outweighs White's material edge. The statistics bear this out: across 789 games where White took the pawn, White still only scored 54.1%, so you are winning over 45% of the time as Black.

Many White players don't know the correct response here. If they guess wrong, you can seize the advantage. Here are the three most common errors and what they cost White. Nf3 (29 games played) is an inaccuracy that loses about 1.0 pawns. White should have taken the pawn with 4.Qxe5 instead. After 4.Nf3, you can play 4...Nc6, developing with tempo and keeping your pawn structure intact. Bb5+ (12 games) is a mistake costing about 2.0 pawns. White checks to disrupt you, but after 4...c6 (or even ...Nc6, blocking) the bishop has to move again and you gain time. Nb5 (4 games) is also a mistake, losing about 2.2 pawns. It attacks nothing important and just wastes a move — you respond 4...Nc6 or 4...a6 and White's position looks silly. If your opponent plays any of these, you can exit the opening with a comfortable plus.

The 848-game database tells a clear story: White's best score comes from the most popular move, 4.Qxe5 (54.1%), but even that isn't crushing. Look at the alternatives: 4.Nf3 scores 51.7% for White — barely above even. 4.Bb5+ scores 58.3%, but it's a mistake that the engine punishes — those games likely feature Black not finding the best reply. The real clue is at the bottom: after 4.e4 (four games, White scored only 25.0%) and especially 4.Nb5 (four games, White scored 0.0%), White's results collapse completely. That tells you most White players who wander into this gambit aren't prepared. If you know the right responses, you'll be the one pressing for a win. The only result that's rare is the draw (3.5%) — this is a sharp position where someone usually cracks.

No matter what White plays on move 4, your plan is consistent. Get your knight to f6, castle kingside, and target White's queen if it overextends. The queen on h5 is a liability — if you can chase it with tempo moves like ...Nc6 or ...g6, you'll develop for free. Don't rush to win the pawn back immediately; your compensation comes from activity. If White played 4.Qxe5 and the game goes 4...a6 5.Nce2 Nc6, White's queen will likely go to g3 or f4. You can then play ...Nf6, ...Be7, and ...O-O, and you'll have three pieces developed to White's two, with a central pawn majority to boot. The Hulsemann Gambit is a real opening where knowledge beats surprise — and now you have the knowledge.
