A82 Dutch Defense: Staunton Gambit
Also filed here: Rat Defense.
A82 holds six named lines from two openings, most of them (five) under Dutch Defense. It leaves A80 (Dutch Defense) with 2.e4. White’s pieces and pawns attack nine squares in Black’s half, the most of the 20 Dutch Defense codes. Material is no longer level at the end of four of its lines; the widest gap, one pawn in Black’s favour, comes in Dutch Defense: Blackmar’s Second Gambit. Black, to move in that position, has 21 legal moves, the third-lowest count of the 20 Dutch Defense codes.
