assume no reads

there's enough turn cards that can be really good for me so I'd want to call a bet, but i dont think i can call a raise if i bet. HU id bet, but 3 handed is there more value in checking?

assume i have a read that CO min bets or bets small with weak made hands, but bets bigger otherwise. then, c/c depending on his bet size (if he bets) is def the right idea, right?

assume i have a read that CO and/or SB are decent/tricky opponents who may bluff raise a flop like this to put pressure on AAxx or big card hands or that they may bet out the turn if the flop gets checked through, what's our line then?

With no reads, I think we have to bet. Villain has a very tight range to raise you and you're drawing to two outs on the turn at best if he does. Checking is bad because we can't reasonably call a turn pot-sized bet that isn't an 8 either, imo.

Bet $4.

plenty deep enough to fire a barrel and see what happens

Agreed. Throw out a feeler. I think the overwhelming belief of our villain at this point will be that you have AAxx, as your PF raise and 1/3 bet on semi-junk coordinated board tell that tale. Odds are no one flopped a 2 pair on you here. Unless someone mined their set you and your "AA" are still good here. If you get a caller, reevaluate on the turn because if you can turn a top set or a OESD, it's going to be hella concealed and ripe for money making. Obv fold to any sort of resistance/re-raise.

Just want to add that if you're going to make bets this size, you have to do it when you flop the nuts too, at least sometimes.
