Overview

Owen Defense: Unicorn Variation 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.

The line arises from 6 plies — specifically the moves 1. e4 f6 2. d4 b6 3. c4 Bb7.

The line refines Barnes Defense, which traces back to the root opening King's Pawn Game.
