Van Geet Opening
Quick reference
1.Nc3, also called the Dunst Opening after American master Theodore Dunst, develops a piece on move one without committing to any pawn structure at all. Dutch international master Dick van Geet built an entire practical repertoire around it and gave it its more commonly used name today, using the move's genuine flexibility — it can transpose toward an open e4-style center, a closed English-style setup, or something entirely its own — to steer opponents into positions they hadn't specifically prepared for.
Flexible, not decisive
This is nowhere near dubious — a developing knight move can't be objectively bad on its own. What limits it is that the flexibility is largely one-sided: White gets to decide later what kind of game this becomes, but doesn't gain any concrete advantage from the move order itself. Most club players who could play the Van Geet just as easily reach similar positions through 1.e4 or 1.c4 directly, with the benefit of far more established theory to lean on if things go wrong.
Where it bites hardest
The sharpest test is 1...d5 2.e4, striking the center immediately and daring Black to prove the extra flexibility didn't cost White anything. After 2...dxe4 3.Nxe4 Nf6, attacking the centralized knight, 4.Ng3 retreats to a useful square eyeing f5 and e4 again later — a common and thematic knight route in these open-center Van Geet lines, and the point at which most club opponents, unfamiliar with the specific move order, start making small inaccuracies that a more standard opening wouldn't have provoked.
Don't try to out-flex a flexible opener
Matching White's flexibility move for move is the wrong instinct against 1.Nc3 — striking the center directly with 1...d5 or 1...e5 works better. Concrete central play forces White to show a hand that the whole point of the move order was to keep hidden a little longer.
When White follows up by fianchettoing rather than pushing e4, the game often heads toward structures much closer to the English Opening, which covers that flank-development family in far more depth.

Frequently Asked Questions
Is the Van Geet Opening the same as the Dunst Opening?
Yes — Theodore Dunst's name attaches to the earliest American analysis of 1.Nc3, while Dick van Geet's name is more commonly used today because of how extensively he played and wrote about it in the mid-to-late 20th century. Both names refer to the identical first move.
Does 1.Nc3 rule out any particular White setup later?
Not really — it's compatible with transposing into an open e4 game, a closed English-style c4 setup, or even certain d4 structures, depending entirely on White's second move. That range is the opening's whole selling point, even though it doesn't force anything by itself.
Why doesn't this get taken more seriously given how flexible it is?
Flexibility for White doesn't automatically translate into an advantage — Black gets to react to whatever White eventually commits to, and in most lines ends up in perfectly normal, well-understood positions anyway. The opening's real value is practical unfamiliarity rather than any lasting structural edge.
