Transpositions with Nc6 and Bg7

The engine's preferred continuation for Black's top choice runs Nc6 c4 Bg7 Nc3 d6 O-O, establishing a harmonious setup with pawns on c5 and d6.

Central and Flank Alternatives

Other setups offer distinct strategic paths for Black. The immediate development Nf6 (+0.29) leads toward symmetrical or King's Indian structures following Nf6 c4 Bg7 d4 d5 Nc3.

The aggressive flank thrust h5 is evaluated at +0.43, meeting h5 c3 Nc6 e4 Bg7 O-O, though it slightly lags behind the standard piece developments in engine evaluation.
