Against the KID when the centre is blocked exchanging the LSB is possibly an even more favourable strategic objective.
An idea that Botvinnik suggested long ago was wait for f5, then play exf5 and follow up with f4 so you get the dangerous g-pawn off and halt the f-pawn locking in the lsb. I've tried this and it actually works well, but I could almost feel my opponents were getting confused through the screen, a long wait to the next move and it didn't feel like I was gaining advantage properly as much as was just getting one through a trick, and it wasn't fun for them either, so in the end I just played the mainlines.
In the Mar del Plata with the g2, f3, e4, d5 pawn chain a lot revolves around what happens after black moves g4. Playing h3 at the right time and setting up the pieces to attack g4 and liquidate everything the moment it's played works well and white should have the better endgame, it's a very clean system that works well when done right.
Hey people i would like some help and advice on how to face the king's indian. My main accounts are 1400-1500. I know the general themes of queen-bishop battery, exchanging Black's dark square bishop and then h,g pawns go brrr🤣. I've tried the jobava london set up against KID with good results. What i need help is when I've started with d4,c4 what kind of path should i follow? Any help is welcome
