note that 15-30 has a 2/3 sb structure

Suppose its folded around to you and you are in the sb and the BB is moderately aggressive (ie- 2 AF). You know you can play 2-7o here, but if the bb raises you are pretty [censored]. How do you approach these situations? Does the at-first-greater implied odds make up for the risk of being raised and being out of position the entire hand?
