Italian Game: Giuoco Piano: what should White play?

In the Italian Game: Giuoco Piano, White's most critical choices revolve around central expansion and king safety, with c3 and Re1 sharing the highest engine evaluation of +0.19. The traditional thrust c3 remains the most popular approach, appearing in 47.1% of recorded games (589K recorded), while the modern rook maneuver Re1 provides a flexible, piece-oriented alternative chosen in 3.6% of games (45K recorded).

Strategic Plans: c3 Versus Re1

The standard plan with c3 prepares queenside expansion and supports an eventual push in the center. An illustrative line runs c3 Nf6 b4 Bb6 a4 a6, where White immediately gains territory on the queenside. By contrast, Re1 focuses on reinforcing the e4 pawn early, keeping the rook active along the half-open or potentially opening e-file. The engine evaluates Re1 Nf6 c3 Bb6 d3 O-O at +0.19, showing that White often transitions back into typical pawn structures after securing the e1 rook.
