  IMlday: Back when I was a 13-year old B-player I remember getting the Varna Olympiad bulletins (in Bulgarain algebraic!) and being really really impressed with how Petrosian managed to avoided trading dark-squared B's. The 'Tiger' seemed better out of the opening despite his eccentric looking 'Hippo' defence. Nowadays 10..h6 seems ordinary; back then it seemed magical.
Jul-02-09  parisattack: Sort of a 'Half-Hippo' (No early QB fianchetto)- Petrosian played it a few times. In the CG base see also his win against Sabitov.
Oct-17-09  kurtrichards: Tiger played the Hippo.
Nov-17-11  birthtimes: How to play the opening, middlegame, and endgame as Black...instructional on so many levels...
Jun-20-12  Garech: Great game from Tigran.


Jun-20-12  shalgo: What happens if White doesn't start pushing his kingside pawns right away but waits with 51.Kf4?

It looks like running the Black king toward the queenside might not work. White can then create a passed pawn on the kingside. For example:

51.Kf4 Kd5 52.f3 Kc5 53.g4 Kb5 54.Ra1 a4 55.gxh5 gxh5 56.Kg5 Kb4 57.Kxh5 a3 58.Kg5 Kb3 59.f4 Kb2 60.Rh1 a2 61.h5 a1=Q 62.Rxa1 Kxa1

This is a tablebase draw, although White's only move is 63.f5! All others lose. (For example, 63.h6 Rg6+ 64.Kh5 Rg1) After 63.f5 Kb2 64.h6 Kc3 65.h7 Ra8 66.Kf6 the draw is clear.

Can Black improve on this play? Perhaps he could try switching his rook to the side of the pawn:

51.Kf4 Kf6 52.Ke4 Re6+ 53.Kf4 Re5 54.Rc4 Ke6 55.Rc7

I am still not sure whether Black can win this.
