Chess Opening Theory/1. d4/1...d5/2. c4/2...e6/3. Nc3/3...f5

'''1. d4 d5 2. c4 e6 2.Nc3 f5'''

The Dutch Stonewall, contrived through a transpositional trick! This variation avoids the 2. Nc3 and 3. Bg5 lines against the Dutch. Black opts to play f5 only after White plays c4 and Nc3.

Black gets a bind on e4 while creating a hole on e5, but White can play f3 to guard e4 while black does not have similar option to protect e5. White will try to blast open the position by arranging to play e4 at an appropriate time. Black will try to build up against White's King with a kingside pawn roller. Qh5, Rf6, etc. with a King's Indian-type attack on White's King is always on cards. White also has play on the queenside. Black's Queen Bishop is a tricky piece. It could be a problem piece for black in certain variations. In others, it aims for a deadly sacrifice on h3 at an opportune moment, as in the King's Indian.
