Van Geet Opening: Reversed Nimzowitsch: what should White play?

d4! — Excellent Choice!

✅ One of 2 top moves — you found a winning strategy!

Why this move is excellent: By playing d4, you immediately challenge the center and put the question to the e5 pawn. This move opens lines for your d1 and c1, transforming the game into a dynamic struggle for space.

Multiple Valid Strategies

Different paths, same destination: While Nf3 is a standard developing move that most humans (about 3%) would consider, your choice of d4 is much more direct. It forces Black to react to the tension on e5 immediately. Both moves are objectively equal, but your choice leads to a more open, tactical game.

Your Continuation

After d4: exd4 Qxd4 Nc6 Qd3

In this line, your d4 becomes a powerful central figure. Even if Black kicks it with Nc6, you simply retreat to d3 and maintain a solid, space-advantaged position.

What Made This Move Good

You correctly saw: That the c3 already supports the center, making the d4 push perfectly timed. Most players at your level reflexively retreat with Nb1 (an 88% human error!), but you recognized that moving forward is the key to maintaining the initiative.

📚 Takeaway: In positions with multiple good moves, trust your style! Whether you prefer the immediate punch of d4 or the steady development of Nf3, both paths lead to a great game.
