I cannot choose a chess opening.

I always play the following

White :- 1c4
Black :- 1...f5 against 1d4 and 1...d5 and 2... Nf6 against 1e4

These seem to be pretty good according to me. I like these free and easy-moving types of positions without many positional blockades.

possible counterplay for black on c, b and a with the pawns, good placement of the bishop c8 which threatens important squares, white will try to push the black bishop back and there are flaws to exploit on h and g with patience
