Is Fianchetto-ing the Kingside Bishop at the Start as Black a Bad Opening?

I noticed that the chess engine gives a reading of +0.6 after taking the first two moves as Black to fianchetto the kingside bishop, which sounds like trouble for black. Is this a bad opening?

A theory says that fianchettoed bishop are a tiny bit stronger than "regular ones", B>N is a part of the equation. g6 lines are considered "normal".

So, simply no. Anyway, a position can only be a win or a draw.

PS: actually I played KID games and when I started with 1. ... g6 I got a further inaccuracy.

Just a random example: only one inaccuracy, guess what?

It is a good opening

White starts every game with a slight advantage, just because of moving first. And engines famously misunderstand the King's Indian Defense: they see the first half dozen moves as growing that advantage, just because of all the space White grabs in the center. But the whole idea of a hypermodern opening like that is to let White overextend himself, then punish him for it.

I am not anything like a GM, but I've heard a number of them talking; and, as I understand it, the consensus is to just ignore the analysis for opening moves like that. Heck, if you play 1.e4 on some analysis boards, the engine will actually tell you, "Inaccuracy: best move was 1.d4." ;) (At least I swear I encountered this once, somewhere.) In any case, while such analysis is quite useful later on, at the very beginning of a game it should be taken with a grain of salt.

The thing about the King's fianchetto is all about the bishop. Don't trade the bishop for a knight. It will create a death trap for your castled King. The strength lies in the bishop eventually gaining control of the long diagonal...sometimes much later in the game. You might also look into the "Robatsch Defense" :]
