To me this decision is close between folding and 3-betting. Cutoff could be wide and on a button steal, suited aces are usually a good choice for a loose 3-bet to around 3500, given we make it hard for someone to have AA. But if you respect the opener probably has a good Ax or a mid pair, then I think folding is the play.
So to me I probbaly raise > fold >> call.
Hero calls 1,400 (2.33bb)
SB folds
BB folds
Pot: 4,300 (7.17bb)
Flop: Q♠ 8♣ 5♠
CO bets 2,200 (3.67bb)
Hero: ?
Or we take option C. So bottom pair with an overcard and no backdoor flush draw and we really don't know if villian is just putting in a continuation bet or flopped a Q, or may have a pocket pair bigger than 8s. He could just be c-betting with the parts of his range that missed, but most of that is Ax and we hold an ace ourselves. Maybe some KJ, KT bluffs are in play?
so here I think fold > call >>>>>>>> raise.
We caught about the least something that we could with this hand. We do have position so in that sense a call in hopes of getting a free turn might not be the worst thought either, so again I think it's close.
Hero calls.
Pot: 8,700
Turn: 8♦
CO bets 4,000
Hero: ?
This is a really bad card, I think you had close decisions to fold on the first two streets, this should be the escape for sure. Villain is not giving up, meaning I think he's probably on AQ, KQ, QJ, KK or maybe even A8 or QQ to which we are now drawing completely dead. Unless you really think this guy is spewing, and that's just not something I am going to attribute to an unknown, this is a fold.
Hero calls.
Pot: 16,700
River: 5♥
CO shoves 17,000
Hero: ?
We don't know if this card helps or not, but this now screams A8 or QQ to me. We caught the "best" possible card, and it's only good if villain has KK, AQ, KQ, QJ AND is deciding to shove the river here. I think you should have folded the turn, I certainly think you should fold the river even after you get the data point that the river "helps" your hand, you also have the datapoint that the villain is betting into a board that should be somewhat difficult to bluff.
Haven't seen the result yet. I'll see if you have posted it.
