Sicilian Defense: Delayed Alapin Variation, with d6

Definition

The Sicilian Defense: Delayed Alapin Variation, with d6, is a branch of the Sicilian that arises after the moves
1. e4 c5 2. Nf3 d6 3. c3.
By postponing the typical Alapin move c3 to the third move, White first develops a knight, inviting Black to commit to …d6 before the Alapin structure appears. The result is an opening that blends ideas of the traditional Alapin (2. c3) with positional nuances introduced by Black’s early pawn move to d6.

Typical Move Order & Position

The most common sequence is:

1. e4 c5
2. Nf3 d6
3. c3 Nf6
4. Be2 Nc6 (or 4…g6)

After 3. c3, the position features:

• White pawns on e4 and c3 ready to support d2–d4, staking out a broad center.
• Black has committed to a Scheveningen-style pawn structure (…d6, …e6 or …g6) rather than the open Sicilian …d5 break seen in main-line Alapins.
• The early …d6 prevents White’s thematic e4–e5 advance and opens the f8–a3 diagonal for Black’s dark-squared bishop.

Strategic Themes

• Central Expansion. White aims for d4 at a suitable moment, often after reinforcing with Re1 or d3.
• Piece Play vs. Pawn Play. By delaying c3, White keeps the option of developing the queen’s knight to c3 in some lines, trading a pawn center for faster development.
• Black’s Flexibility. The move …d6 allows Black to choose among Scheveningen (…e6), Dragon (…g6), or Classical setups (…Nc6, …e5).
• Transpositional Potential. The game can transpose into a 2…d6 Anti-Sicilian, a Closed Sicilian, or even certain lines of the Open Sicilian if White later plays d4 and Black trades on d4.

Historical & Theoretical Background

The Alapin (2. c3) gained popularity in the late 19th century through Russian master Semyon Alapin. The delayed version appeared later as players searched for fresh Anti-Sicilian ideas with more flexibility. Grandmasters such as Sergei Tiviakov and Evgeny Sveshnikov have experimented with it, while several rapid-play specialists (e.g., Hikaru Nakamura) have adopted it as a surprise weapon.

Illustrative Example

Caruana – Giri, Wijk aan Zee 2014. White employed the Delayed Alapin to steer the game away from Giri’s Najdorf comfort zone, later seizing the initiative on the light squares and converting a complex middlegame.

Practical Tips

• For White:
  • Be ready for rapid development with Be2, O-O, and Re1 to support d4.
  • Keep an eye on the e4 pawn; Black’s …Nf6 and …d5 breaks can target it.
• For Black:
  • Choose a setup you know: Scheveningen (…e6), Dragon (…g6), or Classical (…Nc6, …e5).
  • Do not hurry to exchange on d4; sometimes keeping the tension favors Black’s minor-piece activity.

Interesting Facts & Anecdotes

• Because White avoids 2. c3, some databases mistakenly classify early games under “Closed Sicilian” headings; the line has only recently been codified in modern ECO tables as B53.
• During a post-mortem at the 2019 Saint Louis Rapid, Magnus Carlsen remarked that he chose the Delayed Alapin to “ask one small question” of Black on move two—illustrating the line’s reputation as a practical, low-risk probe.
• The variation was featured in several computer vs. human matches; engines often defend comfortably with Scheveningen structures, prompting grandmasters to seek precise, engine-proof move orders.
