Nc3 {Some consider this as a problem with the Dutch, but I'm  inclined to disagree. Rather, it cannot be right to put the knight in front of  the c-pawn so early. The upside is that White can force Black to adopt a Stonewall pawn structure  and  avoid tons of theory.} Nf6 {There are other alternatives here, but if indeed the lines discussed after move 4 are no good for White, then this seems like a very principled continuation.} 3.Bg5 d5 4. e3 $5 {This move is a bit unusual, but I have spent plenty of time reassuring myself that Black is doing fine after} (4.
