stonewall

He did, by committing to f4 early you're creating a square (e4) where no pawns can attack, and potentially your opponent can bring a piece to later in the game, as well as weakening the castled king position.

Because it would take a book to do that...

bf5 is especially strong after 1.d4 d5 2.f4?! bf5.

simply put, 2.f4 is just = probably. Black basically is just down one tempo compared to the normal dutch. If i just want to play regular chess without much theory, the stonewall as white would probably pop up right next to the london system...

It's a very good opening...

at your level.

Why do chess players feel the need to say things like this?

It's not the need, it's the truth.

A little decorum and a little less arrogance wouldn't go amiss.

With normal play from black (normal development etc) there is very little chance for a kingside attack in the reversed stonewall formation.

• Ba6 seems to slow for me. It will probably lead to an equal game but why play difficult when easy to good enough
• g7-g6 is in my opinion a case of the cure being worse than the disease. With your pawn still on g7 black can play f6 kicking the knight from e5. With a pawn on g6, f6 will be too dangerous as will weaken f6 and g6 to much. It also leaves you open to attacks with h4--> h5 and f4 -> f5. By playing g6 you are actually justifying  the move f4.
• Bf5 seems most sensible to me as you develop and directly hit the weakend white squares. White can hardly trade his white squared bischop as it would weaking the white squares even more. I also like Bg4 after logical white move Nf3 pinning the knight and exchanging it later. With suchs a locked up center white will not have much pleasure of his bischop pair.

Ow and how are you going to get a semi open h-file ? There is no way that black is going to open it after he castled short and unless he plays g6 it will be very hard to force him to open it for you.
