  3. Defending against double fianchetto

My opponent loves to fianchetto so I'd like to learn some general tips on playing against this style.

For example, as white he'll begin with 1. e4 and then proceed to fianchetto, usually both bishops.

Knowing this, how would you open as black?

Very concrete theory. Fianchettoed bishops provide latent dynamism during the whole game even if they are blocked. So there’s nothing you can do „in general.“

If he begins with e4, counter it with e5.
Fianchettoing wouldn't make much sense then (except maybe in some Vienna Fianchetto lines)

Thank you, @Sarg0n and @Vycm.

It's true I've asked a rather general question, so I'm not looking for a silver bullet. Just wondering if any black openings tend to play well or poorly vs white fianchetto bishops.

Fianchetto bishops are strong. A good defence is often to line up a chain of pawns that the bishops must stare at: b7-c6-d5 against g3, Bg2 and g7-f6-e5-(d4) against b3 and Bb2.
Classical example: Petrosyan-Fischer 6th match game 1971: 1 Nf3 c5 2 b3 d5 3 Bb2? f6!
