ok, i guess most GM playing these systems as white are clueless or at least would suffer against u.
No! Most of the GM's play this lines they know that if Black gets active on the Queenside there is no direct Kingside attack for White. Sometimes chess is getting hard to play only White's. I am sorry
How does White blunt Black's Kingside attack in the Petrosian? EASY!
1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 O-O 6.Be2 e5 7.d5 a5 (or 7...Na6 - take your pick) 8.Bg5.
Now Black is forced to play 8...h6 or White will completely dominate after he moves his Knight from f3 to I believe d2. Black is not allowed the luxury in this line of storming the pawns like he is in the Mar Del Plata!
Oh, and the four pawns is not busted. White is fine, and I'd even go as far as saying better, after 6...e5 7.dxe5! (not 7.fxe5) dxe5 8.Be2.
Stronger for Black is 6...c5 7.d5 e6 8.Be2 exd5 9.cxd5 Bg4 with an equal game. 6...Na6 is also interesting and White has had some trouble proving more than equality, but again, it doesn't bust the 4 pawns, and if the London is fine, so is the 4 pawns King's Indian.
What the heck are you talking about?!
7...dxe5 8.Be2? What kind of a joke is this?
