It is a very long story...
Tell us everything you know about...opening....King's Indian Defence!

The general strategy in King's Indian Defence (depends on which line is played, In Saemisch line with f3 white castles long whereas other lines white usually castles short) it is mostly a race between white on queenside, black on kingside.So every tempo is so valuable.
And if white manages to capture black's light square bishop, black's attack will be ''less effective''.

Some ideas I learned :
Kings' Indian defence goals:
your goal? The king of opponent!
his goal? push a pawn to a queen or win material!
You see, our goal is a lot more active, if we get that king, it is just over.
How can we do that? Try to make the center closed.
Look your pawn, that diagonal of c7, d6, e5...forwards the king! That means your preparing a f5, to f5....And then further pawn g3 to g4 to g5 and so far.
Here a example between Garry Kasparov and Korchnoi

I know only about this opening that Radjabov and Kasparov played it!
So, maybe you can learn something from their games!

For Kings Indian defence French variation it goes like this..
1. e4 e6 2. d3 d5 3. Knight to d2 c5 4. c3 knight to f6 5. e5 knight f to d7 6. d4 c*d4 7. c*d4 knight to c6 8. Knight g to f3 g6 .....goes on
There is no King's Indian Defense, French Variation.
In fact, you line is not even a King's Indian Defense at all!
And in fact, it usually directly transposes to the Kings Indian Attack (1.Nf3 d5 2.g3 Nf6 3.Bg2 c5 4.O-O Nc6 5.d3 e6 6.Nbd2 Be7 7.O-O O-o or 1.e4 e6 2.d3 d5 3.Nd2 c5 4.Ngf3 Nf6 5.g3 Nc6 6.Bg2 Be7 7.O-O O-O).

I love it when people start trying to attack on the kingside when I play the fianchetto against their Kings Indian defense
it just isn’t supposed to work like that

This is an opening that Grandmasters -including former world Champion Garry Kasparov- use at the very top level for sharp positions.
For the way to handle the main line with Black, nothing like a game played by Stockfish14 ( blitz rating 3735 starting with the main line you may face
1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Nf3 O-O 6. Be2 e5 7. O-O Nc6 8. d5 Ne7 9. Ne1 Nd7 10.
Be3 f5 11. f3 f4 12. Bf2 g5
