My god, this is going to be complex. Long post, so skip it if you think atmosphere and backgrounds make no difference on how to play a hand...
First, background: I am a reg at this casino, and all but one player at the table knows me and has played with me before. They see me as solid, usually tight, friendly, and chatty. As for me, I am a solid hand reader who tends to play ABC TAG postflop, but a bit loose preflop, as an adjustment to the game. I'm not crazy, but I've definitely added SCs and lower PPs to my range. I can happily dump my air and feel no overwhelming need to c-bet every flop, etc.
The NL games at this particular casino tend to play bigger than others in the area, due to the buy-ins. For the 2/3 game, the buy-in is 100-500, and most of the players in this game are experienced enough to know to buy in for at least 100BB. Game plays like the 2/5 games at neighboring casinos. Much of the play in these games has been influenced by one noteworthy reg (lets call him Vinnie) who CRUSHES these tables, mainly by limping behind with marginal holdings and making huge hands, or calling big pre-flop raises with SCs and the like with the sole purpose of cracking big pocket pairs, and finally relying on his amazing human/body language observation skills to help him read players (he's a former cop who i swear, is the most eerily observant human being i've ever met). This leads to unskilled players trying to play "tricky", which of course leads them into trouble. I try to avoid this trap, though i admittedly find myself doing it from time to time.
I call this TTBLV: Trying To Be Like Vinnie.
The casino is in the process of developing a high limit poker room, to try to break into hosting a big game in north san diego county, and as 2/3 was the largest game running, we were the training ground for some of the dealers on proper procedures for running the board multiple times last night. Keep this in mind...
Now the hand (which i botched entirely):
Heroine (CO): $525 behind, I had bought in for $300 about an hour before and had recently stacked a shortie when he shoved into my KK with JT on a J-high board. We ran it twice and I scooped, ldo. Shamefully, I must admit a slight feeling of TTBLV in this hand...
Villain 1 (UTG): ~$160 behind. Very weak player who gets married to overpairs and has trouble seeing danger on coordinated boards. One of the aforementioned who likes to try to play "tricky". TTBLV.
Villain 2(MP): ~600 behind, has been at the table about as long as I have. VERY solid semi-reg who is currently the only player at the table that I am actively trying to avoid tangling with.
Villain 3(BTN): $700 behind. another reg who demonstrates a level 2 understanding of the game, but plays WAY too many hands and can get super spewy towards the end of his sessions, and I rarely see him cash out chips. Also TTBLV
Villain 4 (BB): ~$1600 behind. This is an unknown player. I hadn't seen him before, and he had played a few non-eventful hands since i sat down at the table. I don't know how he got the stack he was nursing, but at first he struck me as a nit. looked VERY tired...perhaps had been playing all night...
Preflop action:
V1 (UTG) minraises to $6. This screams "monster PP" to me based on my knowledge of this villain. V2 (MP) calls, MP+1 calls, Heroine(CO) sees 7

8

and I call. V3 (BTN) also calls, as do SB and V4. This limpfest (essentially) was a foregone conclusion when UTG minraised. Pot is $37 after rake.
V3 leans over to me and says sarcastically, "nice minraise under the gun to build the pot for his aces or kings". This may not have been proper etiquette, and i "shushed" him, but it basically was the same thing I was thinking at the time.
By the time it gets to me in the cutoff, I feel like my odds are so good to call that i can't really pass it up, especially with a middle SC. Should I have repopped it here? Fold pre? Stop playing poker forever?

I know...stop TTBLV
Anyway, the flop:
J

7

9
SB checks, V4 donkbets $15, V1 calls $15, V2 calls $15, MP +1 folds, heroine ???
I am now wondering if my initial read on V1 as having a big PP is correct. Am also baffled by donkbet of less than half pot by V4 in the BB, as well as V2's call behind the initial raiser. Admittedly, donkbets by random live low limit players always seem to confuse me. For some it means they have the nuts, others a weak made hand, others, a bad attempt at a semi-bluff. I have never ever seen any of them actively donkbetting to induce a raise. way too high level for them, i fear.
OK, next step: I call the $15, V3 folds, SB folds. Pot is now $97 heading to the turn. Is my call here horrible spew? Would raising be worse? Should my cards have been mucked so fast I'm almost acting out of turn?
Turn: 2
BB checks, UTG SHOVES for $139. V2 folds, Heroine ??
I now have a gutshot, a flush draw, and a pair, facing a somewhat large overbet. This reconfirms my suspicions that V1 has an overpair to the board, I still have V4 to act behind with his ~$1600 stack, and I'm left feeling that my major mistake here was not having a PLAN for the hand from the minute I looked at my cards preflop.

*bangs head on felt* shouldn't I have seen this coming?
Oh, and go ahead and add into this mix of fun the fact that we could run the river twice if it came down to me heads up with V1. I honestly have NO idea how this effects odds and outs calculations. Could I consider a "double river" to follow the same rules as if there were still two cards to go? This was, of course, a lot to try to process in the midst of the hand, especially with all the wannabe HSP and PAD players at the table going "you can run it twice, you know!" in my ear...lol
After a brief foray online, it's good to be back, though I was really starting to win online when yesterday happened =/ Anyway, I'm prepared for all the harsh words you can throw at me...believe me, I spent most of the drive home last night trying to decide how to play this hand better.
