The idea

A flexible, fianchetto-friendly flank opening. Instead of planting pawns in the middle right away, White controls the centre from the side and fights especially hard for the d5-square. It can transpose into many other structures and often resembles a Sicilian with the colours reversed and an extra tempo, so it rewards understanding over memorization.

Your plan (White)

Press on d5 with the c-pawn, a knight on c3, and a bishop fianchettoed to g2. Develop flexibly, castle, and keep transpositional options open — expanding on the queenside or breaking in the centre when the moment is right.

Heading into the middlegame

The English is a fight for d5 and a flexible, transpositional game. Fianchetto Bg2, develop Nc3 and Nf3, castle, then pick the plan the centre allows: queenside expansion (Rb1, a3, b4–b5 — a reversed-Sicilian space push), the central d4 break, or simply piling on d5. In the Symmetrical, use your extra tempo to break the symmetry first; in reversed-Sicilian lines, you're playing Black's favourite opening a move up. Understand the plans and the moves follow.

Lines

Symmetrical VariationNew

Black mirrors your moves, so use your extra tempo to break the symmetry first — fight for d5 and expand on the queenside before Black does.

Reversed SicilianNew

When Black grabs the centre with ...e5, you play a Sicilian a tempo up — press on d5, fianchetto to g2, and steer the reversed-colours middlegame.
