E92 King's Indian, Petrosian system, Stein variation

lol this guy :D

never said that, whoever is willing to sit as a toilet

an early b6 is apparently a must, it's underestimated

Interesting lines merowig, are they from gm rep series? Don,t bother with the OP, who isn't interested in interacting with anyone and is just a troll

It basically means the P is you while the other fake modesty patzer is me. Right? Your modesty is fake, and making the difference between the two makes it obvious, or whoever builded up the entire fake construction in the first place.

Apparantly not the GM rep series, although has main idea of h6-h5, followed by bh6 to get bad bishop to work. In lines shown in Speelman game prefers 

16...Be3xB 17RXB Qe7 intending h4, Nh7-f6-h5.

I don't even know what the "gem rep series" are.

It's just a game I studied myself while building my own repertoire, annotated with my modest personal analysis.

It's from a book. The troll can interact with a book as well, if he really wants it. Plenty of them. I can even get it for free.

Koronias has a ongoing book series for quality chess, the Petrosian variation is covered in this one

very similar to your lines upto a point.

I'm aware of the variation 16...Bxf2 but I prefer by far 16...Bc5.

Probably a matter of taste to some extent, I like the move itself.

But also, in the 16...Bxf2 variation, Black knight is still in a6, there is no exchange of pieces leading to a pleasant endgame (or slow White manoeuvers if he refuses it), the b4 push comes very quickly and the c5 push as well (see the strategical pawn sacrifice at move 21th in this game, it is commented in CB database), White can turn the center into a total mess and farewell Black's wing manoeuvers.

So... I stand with 16...Bc5. ;)

Don't have book to hand, but think has black playing c5 himself, and analysis is around Zotnik v Kuzmin 1989.

I needed a book some 20 years ago :)

Kotronias I guess, and Zlotnik

Yes, in the aforementionned Valejo Pons-Cvitan game, Avrukh advises ...c5 at some point.

I like too much the wing manoeuvers to even think about choosing this line. Taste.

Yes, we know about chessbase as well, were using it a bit too some 10 years ago, however with not exactly every possible single item in it, we were lazy I guess. 2 old back then already.
