Loose party bad beat table; flop a monster that improves on turn

[pshabi]

Not too much in terms of reads here. I'm going to street by street, so no one gets jaded by the results of the hand.

Critique all streets please.

Raise the flop next time. Aces and flush draws and gutshots aren't going anywhere. Checking the turn was bad too. If you bet and they have Aces theyre not putting you on a 5 at all and will raise you.

Check/raise the flop (and cap if 3-bet), lead the turn

[PokerSparky]

With so many players between you and the OB, you have to raise the flop.

Lead the turn and get paid big by other aces.

EDIT: Oh my! Not betting the turn is a disaster.

Another vote for check/raise the flop. Except that I'd call a 3-bet with the intention of check/raising the turn, as well.

When the case 5 shows on the turn, that changes my play to leading out &amp; hoping that someone with an A decides to play capping war with me.

Why not lead the frop?

I wouldn't lead the flop. UTG either raised with an A or he didn't, but if he did then he's going to raise my initial bet &amp; probably drive some people out. If he didn't, then you don't get his autobet to play off of and you might not collect any bets from him at all.

Plus, check/raising the flop is consistent with what a flush draw would do, and I'd love for the other players (especially the PFR) to think that's what I have.
