the funny thing about this 2...h6 thing you are speaking of...where you want to prevent a white b or n from getting to g5....is that in the bishops opening white almost never puts anything in g5 anyway. it might be more likely from an italian game (and even then the loss of time from playing h6 does not compensate...white could simply go d4 and open the position with 2 extra tempi) but in the bishops opening white is more likely to play something like f4.
But don't you know, 2...h6 also prepares ...g5 to clamp down on any f4-ideas by White.
Oh..., so cute. At least, now we know why you are in those IMs that talk about theory like GMs but, do not reach +2,400 FIDE rating (like normal IMs do).
An illiterate could search the FIDE site for actual player details.
A moron would not be a able to type "FIDE" at the Google search, though...
