Overview

Owen Defense: Naselwaus Gambit is a gambit, classified under ECO code B00 within the Semi-Open Games family. As with all gambits, one side sacrifices material early — usually a pawn — in exchange for development, open lines, or initiative.

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 5 plies and takes 1. e4 b6 2. d4 Bb7 3. Bg5 to reach the canonical position.

It is a variation of Owen Defense, which itself descends from the root opening King's Pawn Game.
