Unique ways of playing against 1. c4?

Whenever playing black against c4 I feel like I get outplayed in positions the other player knows better. Anyone have any interesting pet lines?

Yeah, of course. 1. ... b6(!) does the job. Ask Sasha Grischuk.

Vishy´s 1...e5 and 2..Bb4! on 2.Nc3 is not bad either (idea: play ...c6 and ...d5). I score well with it.

Against c4, maybe play King's Indian or in short play Nf6. This is what I do.

1... Nh6 !
The opponent will go crazy.

1...b5 !
Escape from the routine!

Resign! A very unique approach

The accelerated Keres variation is what I hate to see as an English player. Dangerous Weapons - Flank Openings has it under "Kostenites".

1...e6 with idea to play in queen gambit declined style even if white did not play d4 is a solid alternative.

very open line is e5, is reversed sicilian defense, and like normal sicilian is very aggressive for black, is very interesting studying this c4 line....!

1...e5! does it.
Carlsen got nothing against Caruana
