The Dutch Defence begins 1.d4 f5 (ECO A80). Black fights for the e4 square at once and aims at active play on the kingside - it is one of the most combative answers to 1.d4.
The price of that activity is a slight weakening of Black's own king with ...f5. The opening leads to several structures: the Stonewall with pawns on d5, e6 and f5; the Leningrad with the fianchetto ...g6 and ...Bg7; and the classical systems.
The Dutch appeals to players who want to play for a win with Black and do not mind a little risk. Botvinnik and Nunn both used it, and it still produces lively play that is uncomfortable for the opponent.

Drag a piece onto the board, or click a piece and then click the squares. The cross beside the pieces sweeps every piece of that colour off the board, and a single piece can be dragged off the edge.
