You don´t avoid it with this, you walk straight into the Vienna gambit, 3... d5.
How to avoid vienna game

If you really don't want to meet the Vienna at all, just don't play e5. Go for the Sicilian (1. ...e4 c5) or even Scandinavian. (1. ...e4 d5)
If you're just looking for a counter to this gambit, play d5 after White plays 3. f4. This is the main line. White will do fxe5. From here, respond with Nxe4. You should be fine from here.

This is one of the openings that you have to really know what you are doing. Just play 1...c6 caro kann if you're not comfortable with 1.e4 e5

recently, I felt that I met vienna game and I was lose. so I don't like vienna game
so I did conceive how to avoid it in the condition e4 e5
how do you think?
I enjoy Vienna Game because I loathe King's Knight. But if you want to do something about Vienna Game, then play the countergambit.
