Chess Opening Theory/1. d4/1...f5/2. Nh3

2. Nh3 Dutch A80 Dutch defence 2. Nh3 A rare but respectable sideline where White chooses to develop their knight to the edge of the board. Despite going against common opening principles, this move is sound. 2...Nf6 is the most common move, continuing with the plan of controlling e4 alongside the f-pawn. The game can progress many ways, but the most common is the Blackburne variation, 3. g3 e6 4. Bg2, where the knight doesn't block the kingside bishop's sight, and is essentially similar to a Bladel but from the White side. 2...e6 usually leads to the same line, just from a different move order, through 3. g3 Nf6 4. Bg2. References See also
