To echo Foucault’s answer, I think you’re best calling and playing flops cautiously. Despite laying villains excellent pot odds, you’re by no means guaranteed to see the flop 4 or even 3 way.

I think shoveling 85bb into the pot with QQ after opening UTG is going to be pretty disastrous in the long run. Don’t get me wrong, I think it’s okay vs. hyper aggro players that like squeezing but, even then, for someone to 3b in MP they have to be aware that 5 more players could wake up with monsters, not to mention the UTG raiser. Even against maniacs, I think I prefer flatting with a plan to check-raise shove most heads-up flops that don’t have an A or K.

Readless, I’m going to strongly consider folding to bets on flops that don’t contain a Q, especially if multiple players see the flop. It’s kind of sick to commit 18% of your stack only to fold an overpair, but you’re not exactly crushing a range as wide as JJ+ and AK. Many players will be much tighter when they cbet after that preflop action. That said, depending on bet sizing and (to a lesser extent) flop texture, calling once in a heads-up pot and seeing how the turn plays out can’t be atrocious.
