This is a bad raise that I would easily open fold, not just because the BB is a huge stack but because the button/SB are also large. You want nothing to do with what's essentially a steal raise here.

So you get called and he underbets the QJx flop. I think you have an average of maybe 5 outs here, but what you do depends on his play. Calling sucks because you're going to be facing another bet on the turn, so IMO, this is a very quick push or a quick fold (keeping in mind in order for the push to work, you have to know he's bluffing/won't call over 50%). There's not really an in between.
