Dutch Defense

The Dutch (1.d4 f5) is the most aggressive Black reply to 1.d4. Black immediately attacks the e4 square and plans a kingside attack with ...Nf6, ...e6, ...Bd6 or ...Bg7 depending on the setup chosen. The opening sacrifices structural soundness (the f5 pawn weakens the king position) for direct attacking chances. It's the choice of fighters - Botvinnik used it as Black, and Nakamura and Carlsen have ventured it at the top level.

Main line: Stonewall

The Stonewall Dutch (1.d4 f5 2.c4 Nf6 3.g3 e6 4.Bg2 d5 5.Nf3 c6) is the classical setup. Black builds a wall of pawns on c6, d5, e6, f5 - rock-solid in the centre and ready for a kingside attack. The dark squares are weak (especially e5 and the d4-h8 diagonal), but Black accepts that in exchange for the attacking chances. The plan: ...Bd6, ...O-O, ...Ne4, then ...Qh4 or ...Rf6-h6 with a direct assault.

Variations

Leningrad (...g6)

Instead of building a wall, Black fianchettoes: 1.d4 f5 2.c4 Nf6 3.g3 g6 4.Bg2 Bg7 5.Nf3 O-O 6.O-O d6. This is a Dutch / King's Indian hybrid. The bishop on g7 is strong, the f-pawn supports a future ...e5 break, and the king is decently safe. Less material-heavy than the Stonewall and more dynamic.

Classical (...e6 + ...Be7)

The original Dutch setup. Black plays ...e6, ...Nf6, ...Be7, ...O-O, ...d6 - a flexible structure without committing to the Stonewall's pawn formation. Less common today but a sound alternative for players who don't like the dark-square weaknesses of the Stonewall.

Staunton Gambit (2.e4)

The classical refutation attempt. White offers a pawn to break Black's central pawn front. After 2.e4 fxe4 3.Nc3 Nf6 4.Bg5, Black has to play accurately. Modern theory says 4...Nc6 or 4...c6 holds, but the practical chances heavily favour White. Many Dutch players avoid the Staunton by playing 1...e6 first (transposing into a French if White doesn't go d4) or 1...Nf6 (transposing into a Leningrad).

Anti-Dutch (2.Nc3 or 2.Bg5)

Some White players prevent the Dutch entirely with 2.Nc3 (going for an early e4) or 2.Bg5 (the Hopton Attack, harassing Black's structure immediately). Both are practical attempts at killing the opening - the Stonewall plan only works if Black gets to build it.

Common traps

Don't open the diagonal: in the Stonewall, the long h1-a8 diagonal points right at Black's king. If you ever play a move that opens it (like ...c5 too early, breaking the c6 pawn), White's bishop on g2 can suddenly join an attack on the king. Keep that pawn chain intact.

Watch the e5 square: in the Stonewall, e5 is the dark-square outpost White most wants. If a white knight reaches e5 and you can't kick it, the whole position becomes bad. Always have a plan for ...Bxe5 or ...Nxe5 ready if the knight lands.

Typical plans for Black

In the Stonewall, the plan is direct kingside attack: ...Bd6, ...Qe8-h5, ...Ne4 cementing the outpost, then ...Rf6-h6 for the rook lift. In the Leningrad, the plan is ...e5 break followed by a King's Indian-style assault. Either way, Black is attacking - if you survive 25 moves of passive defence, you've gone wrong. The Dutch is one of the few openings where Black plays for the win from move 1.
