Thanks for the info Tobias,

 I've been analyzing these positions for a few hours and I think I know less now
than when I started! At short depths the engines think black is ok. When prodded
all of a sudden white is clearly better and then suddenly black is ok again but
wait... You get my point. From a practical players perspective it would be very
difficult to play as black, where as white has many ways to play and risks
nothing. Is 10...b6 refuted? I wouldn't even venture a guess!
Regards
Tony
