Hi all!
I have been preparing for a tournamnt and now i was preparing against a player who plays the birds.I dont know how to play against it as black.

So please help me out nd give your views!
Regards

(Birds opening starts with 1.f4

1. ... Nh6!?

SOS recommendation.

which volume?

@CHESSFRBEGINNERS
You could try this setup: 1. f4 d5 2. Nf3 c5 (You grab most of the center since white has only the f-pawn in play, this should give you a nice advantage)
3. g3 Nc6 4. Bg2 g6 (developing)
5. O-O Bg7 6. d3 Nf6 (developing more)

Here is an example of a nicegame which black won against the bird's opening, although I would have played a different setup (the setup that I mentioned that you should try out above) to not allow white to get a lot of central space: lichess.org/Gs93xhe7#72 .

If you want you can have a look at the Fromm Gambit. Personally, I find it very playable.
I cannot guarantee the correctness of the video.

I would recommend From's gambit
The video above is accurate

I would not suggest to play a gambit, as it is a tournament game. Also, the gambit is rather unsound, look at this line, white simply has an extra pawn:
1. f4 e5 2. fxe5 d6 3. exd6 Bxd6 4. Nf3 Nf6
5. Nc3 O-O 6. g3 Nc6 7. Bg2 h6 8. O-O Bg4
9. d3 Qd7 10. e4

Thanks to all of you!!!

No problem, wish you good luck against your opponent!

I don’t know which SOS volume. But just google, there are some videos online. Btw, I play normal stuff as well.
