Owen Defense
Overview
Owen Defense is a specific line in the Semi-Open Games family (ECO B00), arising from a recognised theoretical position.
The Semi-Open Games group covers semi-open games — replies to 1.e4 where Black declines the symmetrical 1…e5 in favour of an asymmetric pawn structure.
It begins with 2 plies and takes 1. e4 b6 to reach the canonical position.
The line is a first-level refinement of King's Pawn Game.
The line has 6 documented children — Guatemala Defense, Hekili-Loa Gambit, Matovinsky Gambit, and others being widely played.
