The Dutch Defence's name is commonly linked to Elias Stein, who worked in The Hague and recommended ...f5 against 1.d4 in his 1789 writing. The opening later developed into several distinct systems rather than one fixed sequence. Its first move remains memorable because Black immediately contests e4 with the f-pawn while accepting changes to the king's protection.
After 1.d4 f5, Black has made an ambitious commitment. The pawn helps control a central square but no longer guards its original diagonals around the king. White can develop normally or challenge the setup directly. This balance between space, activity and king safety explains why the Dutch requires tactical awareness as well as a plan.
The major structures make different use of that commitment. The Leningrad develops the bishop to g7. Stonewall formations place pawns on dark squares and create a different set of strengths and weaknesses. Classical setups develop the bishop elsewhere. A move that fits one structure may be inappropriate in another, especially when the centre can open quickly.
Practise the Leningrad main line and watch how Black prepares central play after developing and castling. Compare it later with a Stonewall position, concentrating on the bishops and the e5 square. The history gives the first move a name; practical study gives it a purpose. Before launching a kingside attack, check whether your own king and central position can support the ambition.
