"Why would you play dutch in the first place?"
---
I'll try to answer the question, just for the sport. higher-rated players, or Dutch players, are welcome to correct me. let's see how accurate I got.

As far as I know:
Classical Dutch - give up some space for attacking chances. see GingerGM.
Stonewall Dutch - Played by Botvinnik and Carlsen - Positional, Defensive. Space-grabby.
Leningrad Dutch - A try to play K.I.D setup with 2 tempo up because f5 has already been played. Gotham say it's terrible, and that he only plays it because he's lazy.
---
About the diagram, they play 1...e6, and only then f5 - to avoid 2.Bg5!

"people probably play the dutch because they want to lose" ahh, priceless.
There's a commerical with cowboys, when it says "Americans love to win", so someone asked "as opposed to Other nations, who like to lose?". okay, if it's time for jokes, I'm all in:
Shallow and pedantic

My favorite Dutch Defense is a good swift kick to the groin with wooden clogs!
