chess opening

The dutch defence is where black plays an early f5 against white's d5. The stonewall variation is where black places pawns on c6, d5, e6 and f5. This forms a strong pawn chain (hence stonewall) with control over e4 (where black may place a knight) but with some dark square weaknesses *e.g. e5).

thanks for telling

Actually, the Stonewall attack is where white does black's setup. 

The Stonewall defense is where black does the setup.

There is no need for black to play the dutch - instead, the stonewall can result from the queen's gambit declined, and other variations even.

Interesting. I didn't know that the Stonewall attack existed for white. I have never come across it. 

I did know that the stonewall for black could results from QGD and a few other variations.
