It depends on what situation you are in. If you are short, its a shove.
Otherwise you have to guage what you think the other guy is doing. Reraising from the BB seems a bit polarizing to me. He may have you beat bad with JJ, QQ, KK, or AA. However, you could be racing with AK, AQ etc.
Obviously, if you have a read on the guy on the BB that would help. Also, knowing what your image is. Is BB trying to squeeze because you have been stealing alot?
Calling is ok but only b/c you will be in position and can represent lots of
hands.
I do think that folding is actually an option depending on pot
odds and reads. Like I said before, unless he is just restealing with air you will at best be racing so if early in a tourney or something like that i think folding is ok as there will be better spots instead of
gambling.
