Key ideas of Against the Dutch
Put your bishop on g2. It hits d5 and e4 and keeps your king safe.
Against the Leningrad, push the d-pawn to d5. It gains space and blunts the g7 bishop.
Against the Stonewall, the e5 square is a hole. Trade the dark-squared bishops and aim your pieces at e5.
Prepare the e4 push with your pieces. It opens the centre while Black's king is a little open.
The f-pawn has left Black's king. Watch for a queen check on h5, above all after ...h6.
