Svetozar Gligoric is considered one of the greatest KID experts ever lived.Along with Trifunovic he created the Mar del Plata variation , the most popular today line against Classical Variation.Gligoric is also considered one of the best 1.d4 players ever lived so let's see him playing as white against his favorite defense.
One step further:c5-KID

[#3]
Against KID White's aim, as we saw in the above game,is the following set-up
White's plan is to play a well timed d5 and follow with e4.
d5 is especially good if Black has played his bishop to b7 as it deactivates it.
After that the typical plans for white are a3-b4 and e4-e5
Of course that is the best case senario but it's not always easy.Black will also prepare ...b5 and ...e6 counter-attacking white's pawn structure.In some cases white has to stop ...b5 with a4
Diagram 5
Against ...e6 White's most interesting plan is the exchange on ...e6.That will leave Black with 2 weak pawns on d6 and e6.
Diagram 6
Let's see these plans in action in the following game

The exchange on e6 is not always good for White.If you don't manage to take advantage of the weak pawns(e6-d6 or only d6) Black's central majority may prove dangerous.Sometimes it is better to keep the strong pawn on d5 and Bb7 blocked.The resulting pawn structure if Black exchanges at d5 is the following:

The symmetrical position gives white very good chances of a k-side attack
Game 3
The next game is even more convincing for White's excellent attacking chances at k-side.With white , one of the experts of the line and one of the best Bulgarian player of 80's(some say the best) , Ventzislav Inkiov.
Game 4
We have some very good conclusions that worth to remember.
1)The advance of the f-pawn to f5 or the advance of the g-pawn to g5 will give white free use of e4-square for his pieces(especially the knights)
2)White should exchange Black's DSB
3)Important to remember is the retreat of Nf3(to d2 usually or in some cases to e1) followed by the f4-advance(see Game 4).
We will start examining all the suggested openings a little more detailed and we will start with King's Indian defense.
We consider King's Indian defense the following formation:
White has no sensible way to prevent Black from playing the typical King's Indian defense moves.Black temporary surrenders the centre and strikes it after castling with either ...c5 or ...e5.These 2 different central hits create completely different positions so they must be examined as separate openings although it is the same opening.
We will try to understand the pawn structure and we won't examine any lines as they are useless in Trifunovic's suggested line as it is based on understanding and not memorisation.
