King's Pawn Game: Maróczy Defense: what to play after d6?

The King's Pawn Game: Maróczy Defense (ECO B07) arises when Black sets up a hybrid Philidor-style pawn formation with pawns on e5 and d6. While dxe5 is by far the most frequent continuation across ratings, the strongest choice according to chess engines is Nf3, which develops a kingside piece while putting immediate pressure on Black's center. With an engine evaluation of +0.65, Nf3 secures a modest spatial and developmental edge without releasing the central tension prematurely.

Classical Development with Nf3

Selecting Nf3 accounts for 19.3% of games (521K recorded) and represents the engine's highest-rated option. It maintains central presence and prepares rapid kingside piece deployment. An illustrative engine continuation features Nf3 exd4 Nxd4 Nf6 Nc3 Be7, where White's active knight on d4 and harmonious development provide a pleasant opening advantage against Black's passive structure.

The Popular Exchange: dxe5

By a wide margin, players choose dxe5, appearing in 67.9% of games (1.84M recorded). Although it simplifies the position and scores an engine evaluation of +0.32, it reduces White's initiative compared to developmental approaches. The engine's illustrative line continues dxe5 dxe5 Qxd8+ Kxd8 Nc3 Nf6, forcing Black's king to forfeit castling rights at the cost of trading queens and heading directly into an early endgame.

Flexible Alternatives

Other reasonable setups prioritize queenside development or central support before clarifying the kingside. White can opt for Nc3, played in 5.2% of games (140K recorded) with an evaluation of +0.59, illustrated by Nc3 c6 Nf3 Nd7 h3 Ngf6. Alternatively, White plays c3 in 7.6% of games (207K recorded, +0.31 eval) or the rare Ne2 (+0.36 eval), both keeping options open while supporting the center.
