Sicilian Defense: what should White play?

In the Sicilian Defense after an early central strike by Black, White's strongest and most common continuation is exd5. This capture liquidates central tension, challenges Black's pawn structure, and secures an engine evaluation of +0.98. Across 1.70M games recorded in this position, White chooses this option in 83.0% of encounters and scores 56.5% of points.

The Strategic Value of exd5

Choosing exd5 accepts the challenge against the pawn on d5 and forces Black to invest tempi or positional concessions to recapture. In the primary continuation exd5 Nf6 Bb5+ Bd7 Bxd7+ Qxd7, White develops with tempo by checking the enemy king before trading off light-squared bishops. This sequence preserves White's lead in activity while leaving Black's queen exposed on the d7 square.

Alternative Continuations for White

White occasionally employs alternate setups, though none yield the same statistical advantage as the main capture. The check Bb5+ appears in 4.8% of recorded games (81K recorded) and achieves a +0.24 evaluation, leading into Bb5+ Bd7 Bxd7+ Qxd7 exd5 Qxd5 where White scores 53.1%. Natural development via Nc3 is seen in 7.2% of games (122K recorded), but after Nc3 d4 Bb5+ Bd7 Bxd7+ Qxd7, Black pushes forward to contest space, leaving the engine evaluation at -0.14 with a 50.1% score for White.

Quiet Setups and Minor Tries

Other alternatives surrender the central initiative. The quiet pawn shield d3 accounts for 4.5% of games (77K recorded) and an evaluation of +0.13, often continuing d3 e6 Qe2 Be7 g3 b5 where White scores 49.8%. The jump Ne5 appears in just 0.6% of games (9.6K recorded) with an evaluation of -0.02, leading to the line Ne5 dxe4 d3 Nf6 Bf4 Nbd7. Because these secondary moves allow Black easy equality or counterplay, theory heavily favors the primary capture on d5.
