== Extra tempo v's Pawn structure == 

 "The KIA is a mirror image of the setup adopted by Black in the King's Indian Defense. Yet, because of White's extra tempo, the nature of the subsequent play is often different from that of a typical King's Indian Defence." 
 This is POV but I believe the above is incorrect, the reason subsequent play is often different is because of the pawn structure adopted by Black is unlikely to be those adopted by White playing against the KID.
