Sticky Goo Defense

A very cool variant I invented for 1. e4 e5 2. d4 dxe4 3. Nc3 f5. I call this the Sticky Goo Defense, its designed to counter a hyper-aggressive black pawn pusher. This allowed me to win a relatively easy match in 8 moves against a higher tier opponenet. See if you can spot a weakness or a way to improve it.
