Bird Opening : que jouer après Nf6 ?

c4! — Excellent Choice!

✅ One of 5 top moves — you found the engine's favorite in a flexible position!

Why this move is excellent: By playing c4, you are immediately challenging the center and exerting pressure on the d5 square. This move is highly sophisticated and rare for human players, as it transitions the game into a Bird's Opening/English Hybrid structure that is difficult for Black to meet.

Multiple Valid Strategies

Different paths, same destination: While most humans instinctively reach for Nf3, your choice of c4 is objectively the strongest. It creates a more complex struggle by preventing Black from easily establishing a pawn on d5. Whether you prefer the solidity of e3 or the flank pressure of g3, all five moves maintain the balance.

What Made This Move Good

You correctly saw: That the f4-pawn alone isn't enough to control the center. By adding the c-pawn to the fight, you create a "pincer" effect on the central squares. Most players at your level overlook this move entirely, opting for simpler development, but you found the most testing continuation!

📚 Takeaway: When you have multiple good options, choosing the one that creates the most problems for your opponent—like c4—is the mark of a strong player.
