Grob White Elo1000: what should White play?

In this position from the Grob, White's most effective continuation is c5, which gains central space while directly targeting Black's misplaced knight on b6. By kicking the piece immediately, White takes the initiative and earns an engine evaluation of +0.72. Across the database, 2,645 games reach this position, where pushing the c-pawn stands out as the only option that grants White a clear advantage.

The strategic point of c5

Advancing with c5 punishes Black's early knight maneuver by compelling the piece to relocate again. The primary illustrative continuation runs c5 Nd5 d4 c6 e4 Nc7, where White seizes broad spatial control across the center with pawns on d4 and e4. With Black's minor pieces driven backward into passive defensive squares, White establishes harmonious piece development while preserving the advanced g5 flank pawn.

Alternative moves and their drawbacks

Other choices forfeit White's initiative and allow Black to claim an edge. Passive options such as e3 evaluate at -0.25 after e3 d5 c5 N6d7 d4 e6, handing Black time to strike at the center. Defending the pawn cautiously via Qc2 yields -0.39 following Qc2 d5 cxd5 Qxd5 Nf3 Bf5, while d3 evaluates at -0.45 in the line d3 e6 Bf4 d5 Qc1 dxc4. Finally, attempting piece development with Nc3 leaves the pawn vulnerable, dropping to -0.53 after Nc3 Nxc4 e4 Nb6 d4 d5. Consequently, direct expansion with c5 remains the principled response.
