It seems obvious that all the programs like Rh5.  The worry is that this is
a possibly bad move on a deep enough search, although I don't believe this
myself (yet).

Kasparov seems to think that Bg7 is best.  But when he 	says 'best' I am not
sure what that means, exactly.  IE 'forced win'?  'good prospects'?  Etc.  And
of course he _could_ easily be wrong, although I would tend to not think this
is the normal case...

Your 1.24 is getting closer to DB Jr's score than mine reached, although I
didn't let it run overnight.  Think I will crank it up and let it burn for
a while myself...
