Kádas Opening: what should White play?

In this position arising from the Kádas Opening, White maintains a modest advantage and should prioritize central expansion with either e4 or c4. While the engine narrowly prefers e4 with an evaluation of +0.58, the flank push c4 (+0.49) directly contests central territory in King's Indian or modern defensive setups. With over 54,000 games recorded from this position, establishing control over the center remains White's clearest strategic direction.

Central Claim with e4

The most frequent choice is e4, appearing in 39.1% of games (21K recorded) with White scoring 53.1%. By pushing the e-pawn, White seizes broad space across the board while taking advantage of Black's early wing commitments. An illustrative engine continuation follows e4 Bg7 Nc3 d6 Bg5 Nf6, where White steadily develops minor pieces around a secure central foundation.

Flexible Setups with c4 or Nf3

The engine's top positional suggestion is c4, which occurs in 8.0% of recorded games (4.3K recorded) and yields a 51.3% score. It often transitions into classical queen's pawn structures, as seen in the continuation c4 Nf6 Nf3 Bg7 Nc3 O-O. Alternatively, Nf3 is chosen in 35.5% of games (19K recorded), achieving a 53.5% score and an evaluation of +0.47. It frequently transposes into similar territory after Nf3 Nf6 c4 Bg7 Nc3 O-O, preventing Black from challenging the center immediately.

Alternative Knight and Pawn Moves

White also tests Nc3 in 12.3% of games (6.7K recorded, scoring 53.6%), leading toward lines like Nc3 d5 e4 dxe4 Nxe4 Bg7 with an evaluation of +0.36. Less ambitiously, e3 is seen in 5.2% of games (2.8K recorded) with an evaluation of +0.22, where White scores only 46.7% after e3 Nf6 c4 Bg7 Nc3 d5.
