Gambit Idea?
Sort:
It's certainly an odd-looking gambit, IMO.
However, it's been tried once: http://www.chess.com/games/view.html?id=966845#
Didn't work too well, because it creates some very nasty opportunities for a Fool's Mate sort of setup; this ends up costing White almost all of his kingside pawns early in the game.
after bf5 check white blunder should of just captured with rook
I should try 1 c4 - b5 as a gambit...... But black should struggle to win the pawn back....
if you're not a fool, you won't be mated. N-f3 attacks the "Fool's" square [h4] and develops a piece while stopping the advance of the f4 pawn. Followed by pd4, which attacks f4, Black has to decide on whether it is to his favor to defend f4 or leave it to the bishop so that his floundering center control can be managed. And even if you don't get to castle, your pawns should be very open allowing your king to move freely under threat of check. You won't have to worry about attacks from blacks pieces if you play this right; he should be down in development and center control. After all of this is over you at least can benefit from a deadly positional advantage: an open F-file for your Rook, either obtained from King-side castling, or, with actually less risk to your king, developing the white-squared bishop. That way, black will be under pressure if he chooses to king-side castle.
P.S. : I'm not being defensive or dogmatic; these are points I would like to be considered or logically dismissed to better understand strategy in chess outside of this opening [just some kinds of basic do's and don't's].
Try these lines: 1. c4 ... e5 2. f4! ...e5xf4 (?)
