The engine-preferred move is cxd5, offering an evaluation of +0.56 and resolving the central tension while preparing an advance on the kingside.

Central Clarification with cxd5

The capture cxd5 immediately challenges Black's pawn structure and relieves the dual pressure against d4 and c3. An illustrative engine continuation demonstrates how play can unfold: cxd5 exd5 e5 Ne7 Nf3 c5. In this sequence, White gains space in the center with an advance to e5, meeting Black's counter-strike against d4 with classical piece development.

Another highly evaluated option is Bd2, which carries an engine evaluation of +0.60 across 9.3% of games (20K recorded). By directly breaking the pin on the c3, White scores 54.2% in this line.
