The Dutch Defense 1. d4 f5 is an attempt to create an imbalance in the position on move one and prepare for a King-side attack by Black. Most common variations are The Classical: 1. d4 f5 2. Nf3 Nf6 3. g3 e6 (and a later d6); The Stonewall: 1. d4 f5 2. Nf3 Nf6 3. g3 e6 4. Bg2 d5; and The Leningrad 1. d4 f5 2. Nf3 Nf6 3. g3 g6 with play much like the Kings Indian Defense without having to manouver the Knight to get the f-pawn to f5. Sometimes White avoids the fianchetto and plays e3 and Bd3, though these are less common at higher levels. A number of move 2 tricks have been employed by White to gum up Black's desired setup: 2. e4 (Staunton Gambit); 2. Bg5; and 2. Nc3.
