I gather you don't want BB to call you? That you just want to take down the blinds?

It doesn't look to me like stealing the blinds once does a lot for you. If MP2 wins an all-in hand in the next round or so, you'll still be tight with 2 others for next to be blinded out, depending upon whether there are antes and exactly when the blinds go up again.

And to answer your question, I think a normal BB would call you with any pocket pair or any ace - just the hands that would be favored to win against you. I say that because he can survive losing an all-in, although it would hurt him - he would still have a slight chip lead on SB and MP1 (after he takes the blinds) and MP2. But if he wins the all-in, he pulls even with the chip leader, and anyway he probably knows from reading 2+2 that the bubble is time when chip leaders should be building their stacks.

So, the safest thing is to wait and see what happens to MP2, but if you want to be proactive, you might try to get BB to call you with a bad hand. How? Well, think about this - he's the second biggest stack, but the biggest is to his immediate right. Thus, he presumably hasn't been able to do much bullying because he doesn't know what UTG will do. But his BB is the one time that he doesn't face that uncertainty - UTG has already folded. So, what if you raise to 3000, like you want to force him out? He may react by thinking you'll be concerned about the pay bubble and think he can easily force you off your hand by going all-in on you - then you call him.
