Italian Game: Giuoco Pianissimo, Normal: what should Black play?

In the Italian Game: Giuoco Pianissimo, Normal, Black faces an immediate pin against the f6 knight caused by the g5 bishop. The primary recommendation is h6, which directly questions the bishop and holds an engine evaluation of +0.14.

Relieving the Pin with h6

With over 1,057,835 recorded games reaching this tabiya, h6 remains the critical test of White's setup. By attacking the g5 bishop immediately, Black forces White to decide between retreating or yielding the bishop pair. An illustrative engine continuation demonstrates this dynamic via h6 Bh4 Be7 Bg3 d6 a4, where Black reroutes the dark-squared bishop to e7 to cleanly break the pin while maintaining a solid pawn structure in the center.

Central and Queenside Alternatives

Black also possesses several viable alternatives that delay the confrontation on h6. The waiting move a6 scores an engine evaluation of +0.21, anticipating queenside expansion, as seen in the line a6 Bh4 h6 c3 g5 Bg3. Classical development via d6 evaluates at +0.22 and follows d6 Nc3 h6 Bh4 Bg4 h3, creating symmetry in central piece activity.

Positional Adjustments

Other sound setups focus on prophylaxis or immediate unpinning. The direct retreat Be7 is evaluated at +0.28, continuing Be7 Nc3 d6 a4 h6 Bd2, which neutralizes the pin without creating kingside pawn weaknesses. Alternatively, a5 evaluates at +0.33, with the continuation a5 Nc3 Be7 h3 d6 a3 securing space on the flank before addressing the center.
