It looks like both moves lose and Fritz 8 is switching from b5 and Bb7 as the scores drop worse for one move then the other. Don't blame Junior...I think the position is lost no matter what is played. Look what Fritz 8 shows after a long search. Both b5 and Bb7 scores drop as the search gets longer, and the program bounces back and forth beween the moves. Seeing this you can not be too hard on Junior as Fritz 8 would also chose b5 at certain times. If Bb7 is drawing then Junior was unlucky because I bet it would also bounce between Bb7 and b5 in its search.
