Birds opening

Is it normal to play f4 as a starting move for white because many players play c4 why don’t they do f4

This is just a test question, right?

1.f4 and 1.c4 are not symmetrical.  If the Queen and King served the same functions, then yes, 1.c4 and 1.f4 would make no difference.  But here, they are vastly different.  1.c4 is the 4th moth popular first move (behind e4, d4, Nf3) while 1.f4 is 6th and for a reason.  The king as opposed to the queen.

I like the Bird's, but requires good handling and understanding of the position (not necessarily positional understanding, but that would be beneficial as well)

I have recently studied the Bird's Opening and it can be successful. Next few moves for white: 1. f4 2. h3 3. Kf3 4. e3. This is a sound kingside defense, but you may be more likely to castle queenside. Black may control the center more than White, but try to play and crush the Kingside if he dares to castle 0-0.

How do you play Kf3 on move three? That takes some real skill

I meant Nf3

Typo

oh.

H3 blocks bishop from destroying the Kingside Knight defense.

h3 is not needed.

I like to add h3 anyway, but if you think no, go ahead. I think it' the player's choice because it doesn't matter apparently. You're going to want to keep your knight sometimes, then play h3 to ensure that! Don't care? Listen to SNUDOO.

I mean, the king's knight is not needed.

I have two books on the Bird's (Move by move, C. Lakdawala and Bird's opening, T. Taylor). Taylor and Lakdawala both say after 2. ...Bg4, you should play e3, then h3. Both give examples of Danielsen destroying the guy in the variation I listed. 

Ok, you may say that but I am just giving an example of how I like to play the Birds, of course, it doesn't have to be played my way so by all means, PLAY HOW YOU WANT TO PLAY. 

I'm giving an example of how I like to play*.

I enjoy f4 but if black plays e5 I just think it's bad for white unless you like Kings Gambit and willing to play e4 on 2nd move.

well does anyone here play f4?

I have played f4 countless times, just tell me what move number you wanted.
