OOP - Out of position.
Not really OOP in the sense that you have the button, but with the action having yet to be closed by the original raiser in MP, you risk getting reraised and being blown off your 88s. It would be ugly and you'd be lighting 10bb on fire.
In other words, you're counting on the MP flatting and closing the preflop action. If you're confident he's rarely going to reraise, then it's a standard call. Otherwise, you're in position and I like how you had the button, guaranteeing the option of checking behind because he's never bluffing
the river in that spot.
I think the +EV move would be to fold despite flopping the bottom end of the straight draw, which would be dominated by QQ/AQ (if someone didn't have KQ already), and there are enough players to think that someone has a flush draw, dirtying more of your outs. Your draw's much stronger on a 765 board, which you could technically just open-shove the flop profitably against the overpairs, versus the J109 flop which is suicide.
Another detail is that you're OOP on the flop in that it checked through the blinds - then the CO bet, and after you call, both of you would be checkraised on this flop a fair percentage of the time.
A good thing to think about in these sort of spots is "What would need to happen in this hand for me to confidently value bet the river?" Here, you kind of need a running full house, no?
On the turn, the CO's check-call turn kinda looks like the CO possibly having AK of diamonds on the flush + broadway draw. He misses the river, I'd just check it back.
Another set of possibilities in my mind is that *he* flopped a set with JJ/10s/9s. Then his c-bet (are the rest of his non-club/non-diamond AK/AQ combos really c-betting into 4 other players on a board *that* wet and connecting with the callers?) makes sense. Horrible turn card, so he can only check-call to boat up or failing that hope for a free showdown. If you've seen him 3-bet 1010s and 99s so these fall into his range, then the other play is to shove the river to fold these hands out. If your read is that he may have one of these hands.
If he's a trapping type of player, you can infer if he had KQ/AQ. With two flush draws, would he really c/c the turn with any combos except KQ/AQ of diamonds/clubs? With QQs alone, he'd get the rest of the money in to protect his hand after you bet I'd think. I'm leaning toward the AK/KK/JJ/1010/99 side of his range rather than the QQ/KQ/AQ range. Just speculation.
Interesting hand and runout. What did he have?
