The first diagram is winning for White. It's winning for White without the Gambit. The "gambit" by Black just makes matters worse for himself.
The Stonewall setup (f5/e6/d5) is TERRIBLE if White is still able to get his Bishops to f4 and d3.
For example: 1.d4 f5 2.c4 Nf6 3.Nc3 e6 4.Nf3 d5?? (4...Bb4! =) 5.Bf4! followed by 6.e3 and 7.Bd3. This is TERRIBLE for Black. Your line, throwing a pawn away with it, is even worse! The fact that White has no pawn on c4 is meaningless. Black's problem is the dark squares!
The fact that White can play Bf4, e3, and Bd3 makes the other lines by White irrelevant. It only takes one line to bust the idea.
The Stonewall should be a "Last Resort" and should only be played if White has committed to g3. If White makes no move to fianchetto his Bishop, Black should play ...b6 and ...Bb7 AFTER he has solidified control of e4, like 1.d4 f5 2.g3 Nf6 3.Bg2 e6 4.Nf3 d5 5.O-O Bd6 6.c4 c6.
But after say, 1.d4 f5 2.Nf3 Nf6 3.Bf4 e6 4.e3, once again, 4...d5?? is a blunder, and so would 4...b5? 5.cxb5 d5??.
Don't try to re-invent the Wheel. The Dutch Defense is WAY older than you or I am.
hey so i played 6 moves against the engine "of course i set up the pieces before"
the setup is d4 f5 c4 b5 cxb5
1.d4 f5 "dutch defense" 2.c4 and then the "gambit" is b5 after that the bot I guess accepts it and eats the pawn cxb5 and i push to the middle d5
if you play the dutch defense 2.c4 you could just push to d5 and they won't eat you since you could eat with the queen
