The Adorjan Defence arises after 1.c4 g6 2.e4 e5 in the English Opening. ECO code: A10.

Overview

Named after Hungarian GM András Adorján, this line sees Black combine a kingside fianchetto setup with an early ...e5 to seize central space. The resulting positions resemble reversed Sicilian Defence structures with Black's bishop on g7.

Strategic Themes & Plans

Black aims for a solid, flexible position with the bishop on g7 exerting long-diagonal pressure. White can proceed with Nc3, d3, and Nf3, or play d4 to challenge Black's centre directly. The position is sound for Black and can lead to rich strategic middlegames.
