First of all, your output does in no way state which scores are bounds
and which are exact, so everyone will assume they are *all* exact.

Secondly the point of the position was that Bxa8 is a *really* bad move,
and a score of <= +3.81 is not exactly suggesting this. Crafty's +0.56
eval (contrary to +3.16 for b6) gets a lot closer to the point, for
example.
