B01 Scandinavian Defense

Also filed here: Van Geet Opening.

B01 holds 46 named lines from two openings, most of them (45) under Scandinavian Defense. It leaves B00 (King’s Pawn Game) with 1...d5. Material is no longer level at the end of 21 of its lines; the widest gap, two pawns in White’s favour, comes in Scandinavian Defense: Kloosterboer Gambit. With 46 named lines it is the second-largest code of the 100 codes in volume B.
