A81 Dutch Defense: Fianchetto Attack
A81 holds five named lines, all under the name Dutch Defense. It leaves A80 (Dutch Defense) with 2.g3. Black, to move in that position, has 20 legal moves, level for the fewest of the 20 Dutch Defense codes. White’s pieces and pawns attack four squares in Black’s half, level for the fewest of the 20 Dutch Defense codes. None of its five lines contains a capture.
