Sandro,
Jan and I are talking about 20. g3 instead of 20. gxh3 as a second way to an
advantage. Yes, 20. gxh3 looks good for white, probably 31. Rxh6 is white's
mistake.
Jan, regarding your game below, I am not sure that Rybka played it correctly.
Black needs to stay more active on the queenside. After for example 29. c4,
black is already busted.
I am reminded of the following game (pasted below). Afterwards, Kasparov
explained that the pawn on h3 was worth a piece. Of course, Kasparov likes to
exaggerate - but have a look.
