Was a long time since last post on this forum.
It appers that Ivanchuk tried g3 system against Radjabov yesterday and Radjabov play this aggresive line against it and became posinally busted after several blunders including a major tactical blunder that lost the game.

No White always goes h3 in this line (before castling) - otherwise the early ...Qc8 followed by ...Bh3 eases Blacks task considerably. So its a tempo down plain and simple. I see what you mean in that White has castled but in the move order given White could delay castling if he likes transposing to the "main-line" of this sideline, but as it happens I believe 0-0 is decent also. In short - this particular line is complete rubbish for Black.

Dont understand this at all - Black goes ...Bg4 and after h3 just goes back to d7 - he's lost a tempo on a different line which is not so great either - immediate ...Bd7 and ...Qc8.

After immediate ...Bd7 and ...Qc8 White will not play h3 and Kh2, so I don't think you can say that Black loses a tempo. Exactly these moves h3 and Kh2 are supposed to provide the justification for ...h7-h5-h4. If that logic is correct is another matter.
  

The book had the effect good books usually have: it made the stupids more stupid, the intelligent more intelligent and the other thousands of readers remained unchanged.

I've played against this a few times as White, for some reason its popular amongst club players but ultimately insufficeint in my view - I usually play a recomendation of Rogozenko involving b3, Bb2 and eventual Nf4 or Nd5 - once White eventually arranges to put his king safe by castling Blacks whole setup looks artificial and extravagant.

Discovered this game today from Swedish championships, junior class. Black plays very aggresive agianst g3 system and tries to mate white in usual white yugoslav attack style with h5 h4 etc. White won but there are improvments.
