Was the BB known for slowplaying? Or would he protect an overpair on the flop such as Jacks or Queens. I think he would have to raise w/ TT-QQ, KK and AA are possible but they can afford to take a card off. And a 3 is unlikely since the pot is raised? And would small blind bet into the raiser w/ trips? My first thought was to push the flop since most overpairs would want to protect the flop vs overs thus they would have raised. I think theres a good enough chance that your facing a 7x, overs or a lower pocket (hopefully not 77). Plus what Lloyed just said, your stack is getting small (soon to be 10 big blinds next hand) and you need to find a good situation to make a move and this looks pretty good.
