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

In the Italian Game: Two Knights Defense, Knight Attack, Normal Variation, White faces a critical juncture with over 6.6 million games recorded in the database. The engine's highest-evaluated continuation is d4 (+0.77), which immediately challenges Black's central control, while the historic and highly aggressive piece sacrifice Nxf7 (+0.65) serves as a sharp and viable alternative. Moves that fail to contest the center dynamically, such as d3 (-0.29), concede the initiative and tilt the evaluation toward Black.

Central Break with d4

The strike d4 seeks to open lines against Black's king and unseat Black's advanced coordination. In the illustrative line d4 Nxd4 c3 b5 Bd3 h6, play transitions into an open tactical battle where White secures a slight territorial advantage. Striking at d4 prevents Black from consolidating smoothly and yields an evaluation of +0.77.

The Fried Liver Attack via Nxf7

The sacrifice Nxf7 launches the famous Fried Liver Attack, dragging the enemy monarch into the open board. Following Nxf7 Kxf7 Qf3+ Ke6 Nc3 Nb4, White exposes the black king on e6 to sustain immense attacking pressure, retaining an evaluation of +0.65. While statistically slightly below d4, this line poses immediate, severe practical tests for Black.

Passive Alternatives to Avoid

Quiet developing moves forfeit the initiative gained by the early knight sortie. Opting for d3 leads to d3 f6 Nc3 Bb4 Ne4 Be6 with an evaluation of -0.29, while O-O (-0.36) permits O-O Qxg5 Bxd5 Bd7 d4 Qg6. Similarly, Nc3 drops to -0.76 after Nc3 Qxg5 Bxd5 Nd4 d3 Qg6, showing that White must play forcefully with either d4 or Nxf7 to maintain the upper hand.
