Dodging bullets?

So, a decent player 3-bets preflop from the BB. Even if he also knows that MP1 is "hopeless", MP3 is an unknown, and it's less likely that he thinks you're stealing, so maybe you expand his holdings to JJ+/AK/AQ. When he 3-bets you on the flop, JJ/KK are gone, imo, and you're behind everything else he could be holding.

But, you have the NFD plus other outs and 2 opponents who look like they're not going anywhere. So, I don't hate the cap on the flop.

When the Q falls on the turn, you just pulled ahead of AK, and QQ disappeared. That's all. That leaves you behind 6 combos of AA/AQ and ahead of 12 combos of AK. So, folding isn't an option.

Call or 3-bet?

You just lost MP1's dead money. You're situation isn't going to change, no matter what falls on the river. But, you look like a 2:1 favorite, here, IF IT'S EQUALLY LIKELY THAT HE'S HOLDING AA/AK/AQ. The question is, "Are the 3 hands equally likely?" and I think the answer is: you don't have a good enough read. So, call the turn raise, call any river, and see what he shows you.
