Sicilian Defenses

 

Sicilian Defense

The favored position of grandmaster Mark Byerly.  Black will eventually fianchetto both Bishops and thereby maintain strong central pressure via counterattack.

Sicilian Defense - Closed Variation

White avoids opening the center (via Nf3, d4) and allowing Black to take advantage of his fianchetto.  But at a cost.  Black will play d6 and e6,and Qc7 which limits White’s knight development, while maintaining kingside pressure.

.

Classical variation

A symmetrical position.  Both sides have knight outposts along the dfile.  Both will castle into the kingside fianchetto.  Seems a bit drawish to me,

Sicilian Defense - Alapin Variation

White, in this system, attempts to maintain two central pawns.  Three things can happen:  Black, following d4, can allow the traditional exchange, develop normally and hope to counterattack White’s over extended pawn structure.  Black can play d3 or b3 and enter a quasi-slav defense, or Black offer a counter exchange with d5, exd5, qxd5.
