Preflop: 3bet vs the open - once you flat (which is certainly okish) and the SB sqzes I'm not a fan of backraising it - we are pretty deep - and I obv. wouldn't wanna stack off for 264 bbs here. We are IP to both guys, we have a great MW hand - we still dominate big chunks of their ranges. So yeah once you don't 3bet and just peel the open - I'm always just flatting here.
Flop: I'm not really a fan of betting small here - you generally wouldn't do this with your value hands like AQ - and I certainly want to put some hands like middle pairs under some pressure - both villains are pretty capped / rather weak here once they check so I'd bet around 8$.
That being said with all the equity you have you can't really screw this hand up and cbetting small certainly will be a profitable play.
Turn: Just check back and realize your equity
River: Def. giving up
