Nimzowitsch Defense: Kennedy Variation, Hammer Gambit: what should White play?

Bc4! — The Only Good Move!

⚠️ Critical position — You found the needle in the haystack! While 82% of humans miss this, you spotted the most aggressive and precise development.

Why this is the only good move: By placing the c4 on its most active diagonal, you immediately target the weak f7 pawn and prepare to launch a devastating attack. This move forces Black to respond to your pressure rather than allowing them to dictate the pace of the game.

Why Other Moves Fail

The traps: Many players fall for Bb5, thinking it pins the knight, but it actually loses significant ground (+0.59) compared to your choice. Natural-looking moves like a3 are simply too timid—in this open position, every tempo is a weapon, and you cannot afford to "pass" the turn.

How To Find The Only Good Move

Step 1 — Recognize the critical moment: Black has an open center but lagging development. The f1 needs a home where it exerts maximum pressure on the King's side.

Step 2 — Eliminate the traps: Avoid "hope chess" like Ng5. If the opponent can defend with a simple developing move like Be7, your attack is premature.

Step 3 — Verify the solution: The engine confirms that after Bc4 Nf6 Ng5 d5 exd5, White creates massive tactical problems that Black struggles to solve.

📚 Pattern: The f7-Pressure. In e4-e5 openings, the f7 square is the weakest point in Black's camp. Developing the Bishop to c4 is the most principled way to exploit it.
