The key to the fiancetto?

Hello chess.com community! I have a question..

Lately I have been trying out the Kings Indian Defence, which involves playing Nf6 and then fiancetto your bishop on the kingside. Now, the problem is that the knight on f6 is blocking the diagonal that the bishop is supposed to attack.

I've played about 25 games with the Kings Indian Defence now, but the knight often stays there until the endgame. It doesn't have alot of good jumpsquares, since white's pawns are securing the centre and the kingside position. It could go back to the 8th rank, which doesn't make alot of sense. It just seems that the fiancetto'd bishop is wasted on the g7 square.

Another question about the fiancetto: White often comes in to g5 to attack your knight on f6. Now, it's possible to kick the bishop with h6, but this leaves your castle position rather weak. Any other suggestions on how to deal with a bishop on g5?

Any help is appreciated.

f5 is usally the key to many indian defenses to break the center in other words

Thanks alot, I'll keep that in mind!

...Nh5 is also often played, again with the goal of ...f5.

Usually the center becomes closed, after say ...e5 and white's d5, and then black's bishop "goes to sleep" until the center is forced open later (often by tactics, Nxe4, Nxd5, ...f5 exf5 e4, that sort of thing) and it's suddenly got a lot of squares available.

The diagonal of the bishop is less blocked in other Fianchetto defences. However the trick is to plan somewhere useful for the Knight and then you can move it openning the diagonal.
