The Dutch is a very difficult opening to deal with, because it’s a scheme of development where black just sets up his pieces before taking concrete action. White on the other hand doesn’t have many sharp options to punish this, at least not many promising ones. Since countering the Dutch is a work in progress I will just offer something that engines agree with for now.
I won’t even bother suggesting something against the Stonewall, because it is the prototypical anti-computer opening. Maybe white should simply play 2. Bg5 and take it from there.
Play it safe!
