A02: Bird Opening / Dutch Attack

What do you think of the Bird's Opening?

Bird's Opening / Dutch Attack is characterised by the move

        1.f4

Out of the twenty possible opening moves, 1.f4 ranks sixth in popularity in ChessGames.com's database, behind 1.e4, 1.d4, 1.Nf3, 1.c4, and 1.g3.

I played it exclusivly (and developed my own uncommon ideas in it) for 1.5 years.now Im trying to get into the A-class and gave it up, not because I didnt think I could win with it but because I needed to learn a larger variety of structures.

on the popularity subject (for me) its the only one in the grey zone.. the 5 you mentioned lead to a good game, while bird can get too systematic and cramped at times.. and then anything after the bird starts to get super shady imo

The Dunst Opening and the Bent-Larsen attack are OK.
