Overview

Van Geet Opening: Pfeiffer Gambit, Sleipnir Countergambit is a gambit, classified under ECO code A00 within the Flank Openings family. As with all gambits, one side sacrifices material early — usually a pawn — in exchange for development, open lines, or initiative.

The Flank Openings group covers flank openings — systems that delay the central pawn break and instead develop pieces and pawns on the wings.

It begins with 7 plies and takes 1. Nc3 d5 2. f4 d4 3. Ne4 e5 4. Nf3 to reach the canonical position.

It is a variation of Van Geet Opening: Pfeiffer Gambit, which itself descends from the root opening Van Geet Opening.
