Italian Game: Two Knights Defense, Knight Attack, Normal Variation: what should Black play?

Na5! — The Only Good Move!

⚠️ Critical position — White has just pushed d5, attacking your c6. Most players instinctively recapture, but in this specific opening, that is a recipe for disaster!

Why this is the only good move: The move Na5 is a classic counter-attack. Instead of passively defending or falling into a tactical trap in the center, you move your knight to safety while simultaneously attacking White's most dangerous piece: the c4. This forces White to deal with your threat before they can continue their assault on f7.

Why Other Moves Fail

The traps: The most common mistake is Nxd5. While it looks like a free pawn, it invites White to blast the center open. By playing Na5, you disrupt White's coordination. If White tries to keep the pressure with Bb5+, you respond with the solid c6 dxc6 bxc6, gaining a lead in development for the price of a pawn.

How To Find The Only Good Move

Step 1 — Recognize the critical moment: Your c6 is under fire, and the c4 is laser-beaming your f7 pawn. You cannot afford a slow move.

Step 2 — Eliminate the traps: Calculate Nxd5 and realize it leads to the infamous Fried Liver-style attacks where White's pieces swarm your King.

Step 3 — Verify the solution: Look for an "active" defense. Na5 hits the bishop and prepares the following sequence to stabilize: Na5 Bb5+ c6 dxc6 bxc6 Bd3

📚 Pattern: This is the Polerio Defense. In the Two Knights Defense, when White pushes the d-pawn, the knight jump to the rim is often the only way to fight for the initiative!
