e4 f5

I do not know the theory of this gambit but I wanted to play it because I wanted to play somethingf diffrent.It was a quite interesting game to demonstrate the importance of avoiding lack of development in a chess game.

4.f6 is bad.  It allows Black to develop a piece, regain his material, and gain a tempo.  What if White had played a normal move like 4.d4 - which controls the center and allows for Bd3 holding onto f5? Your king is misplaced, you are down a pawn and you have structural issues - this is not fundamentally sound chess.

Really, you won because of your pawn wall, and he move his queen out. Too early. Development did help...

Thanks I need more comments about this gambit.Is it playable?

Maybe black wins 0.1% after my win with fred defence
