About the Dutch Defense
Black answers 1.d4 with 1...f5, grabbing the e4 square. It is ambitious and aims for a kingside attack, but it weakens Black's king a little.
Black controls e4 with ...f5, ...Nf6 and sometimes ...d5 (Stonewall).
A common attacking plan is ...Qe8 to h5 with pieces moving to the kingside.
Beware the e8-h5 diagonal; early Qh5+ or Bg5 tricks can hurt.
