rybka is worried about white playing h5 but apparently disagrees that its objectively best to stop it.

I think Nc7 is fine, followed by Be6. But h5 certainly has it's merits as well.

Now if a program played 0-0 then I'd be concerned!

I do remember those distant days......

[F. Bluemers]

imo h5 is better,white can only wait for black to manouvre around and preparing pawnbreaks.
