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...
