$100 NL: Simple preflop question from the BB

[spex x]

I'd been at this table for a while. Both but button and SB have been pretty solid, but a bit tight/passive, I'd been playing pretty tag. I'd been catching some good hands and 3 betting quite a bit preflop, but not hitting much and having to muck a lot after the flop. So table image was probably a bit more on the laggy side.

Everyone folded to the button, who raised to $5. The SB reraised to $20. I was in the BB w/ AKo. Should I reraise or fold?

Fold or push. Your description of SB makes me lead a bit towards folding, esp if SB is not known to resteal at all. Otherwise, I think this is a good situation to push, as you might catch SB trying to resteal.
