Thanks for your comments, Jordan! FWIW, I had 8k behind in the second pot (not counting the BB), which is 27bb. Agreed about getting looked up light--e.g., JTo in the button when I did shove! However, I didn't want to wait too long to shove for that reason--so A2s from the HJ seemed like my best shot.
Re: the second hand, I really don't like a preflop shove vs. a potentially trappy UTG limp (she was a brand-new player who had just sat down the hand before, with a stack of maybe 50bb). I would have done it with AJo, obviously, and probably also with ATs ...but I think A9s doesn't have nearly enough equity against most of what I get called with. I'm only really happy about seeing 88 or 77 there...just about the rest of her limp-calling range has me crushed, if she IS trapping. I agree I have a lot of FE vs. everyone but the UTG limper, and, as it turned out, I WOULD have had it against her unless she had a very weird way of playing KK or JJ! But at 27bb, I opted to play it safe--at 20bb, i would have shoved, for sure.
Nor do I like the flop lead because I think in a limped pot there are wacky 2 pair hands (including AQ, which many are afraid to 3bet with and therefore might just call vs an UTG limper; A7o, Q7s, maybe Q7o in LP)...as well as lots of 2nd and 3rd pairs , all of whom may call. Since *I* didn't raise pre, I obviously don't have a big ace, so while my hand is disguised, it's not strong enough on that board to scare off all the other limpers--e.g., my opponent would almost certainly have called on the flop with his queen and backdoor flush (unless maybe I made a pot-sized bet, but that's 1/4 of my stack, so that's going to be hard to fold to a shove--yet any shove almost certainly beats me on the flop).
All of this is a strong argument for betting out with a big hand (better than one pair) on the flop, and I would obviously have been thrilled to check-shove a draw (especially a draw to the nuts and/or one with a little extra equity), but that UTG limper is also a factor in not betting the flop. If she limped with a big hand hoping for a raise, betting into her is deadly. If she has KK (or, weirdly, JJ or KQs, or something like that--a hand she wants to play but not call a 3b with pre), she'll probably call the flop, but she'll also call with AA, AK, AQ, or QQ (why else would she trap pre if she didn't want to trap post?)--and then what do I do OOP on the turn? She can bluff me all day long, and she can also get me to pay her off all day long....
I still feel torn about the turn bet (which Carlos speculates may be equal EV to a check), because I can increase my stack by 25%, which for all the reasons you say, Jordan, is worth a lot. However, in a 6-way pot, I think it's nearly impossible to get through without at least one caller, especially after the flop was checked, which I'm guessing is why Carlos prefers a check-fold (and why I probably should have, especially given how much more precious stack size is in a bounty).
I think if I don't bet the turn I MIGHT be able to call a turn bet, depending on size, because of the heart draw...but then I'm OOP and anyone can bluff the flush if a heart comes in. And if a heart doesn't come in, I might still be paying off a two-pair hand or a set, since there are so many more 2-pair hands than usual (Q7s, Q5s, 57o, and all the suited aces).
I do hate to publicly admit an error! But I think folding the river is correct unless I have a heart, as Carlos says, and maybe not even then. Maybe I can call a much smaller bet. But that's the problem with being OOP in a 6way pot--especially a LIMPED pot with wide ranges--which is the argument for not having gotten involved on the turn.
Going back to Carlos's range analysis, I probably should say that there are tons of hands in my range that are better than a weak one-pair hand with which to bet and/or call the flop, turn, and/or river--all the two-pair hands (on the flop/turn), all the heart draws (on the turn), 77, 55, 57, Q7, A7. With all those hands in my range, I shouldn't be getting involved with weak one-pair hands (although that 25% of stack is pretty compelling!!!!!!....and it's also why it was so hard to fold the river.
You can make the argument that if I bet the turn and then fold the river, I'm pretty exploitable to being bluffed whenever a heart comes or the board pairs. I think that's true--and another reason for not betting the turn, given the range analysis: both of us should have stronger ranges than I was assuming (I was just thinking about maybe being good on the turn instead of taking all our ranges into account). Therefore, a weak one-pair hand shouldn't get involved, period, on either street (because having bet the turn, it's REALLY hard not to call the river, and I can be exploited by anyone who knows anything!).
