Knight position in KID

I've always heard that the knight is excellent for h5-f4 maneuvers and also a6-c5  ones too. The knight can also move to e7 or d8 to clear way for the crucial ..f5 advance. If for not these wonderful maneuevers black wouldn't have a good position.

Recently i've heard that the best position for the knight is on f7. This can be achieved through continous maneuvering of the kingside knight in the 6. ..Na6 or 7. ..na6 variation of the KID. I myself don't see much about it..

I usually bring the knight via d7 to c5.  It is a great square and is fairly well maintained by putting a pawn on a5.  From there it has the option of coming back to e6 when attacked in some lines.

These considerations don't make sense in abstract. It depends on the requirements of the specific variation especially in an opening like KID where both players have wide variety of setups to choose from.

Agreed Shakaali; even in my over the board games where it is more about system and less about theory I have seen my knight go to d7, e8, h5, even g4 occasionally.  There are a lot of things white can do to "rain on my parade".  I still like it best when I get the thing to c5.
