Thank you for all the replies so far, I am going to respond to a few of the comments and then on with the story.
Fold. Lol, I mean check. A straight is useless if the flush hits, I would prefer to control the pot than get aggressive right now. Also, your player description is a little confusing because you are using both "villain x" as well as the seat locations.
I do apologize for this, I see now that I was really unclear about the positions the way I wrote the OP, but we're way past the point of editing my way out of this. I kind of identified the villians based on who the main principles are, but hero only had a read on of the few of players involved. And UTG was the only "short stack" otherwise stacks are generally irrelavant in limit.
I should also point out that cash games are played 9-handed in this club, not 10. So I am not sure if that's the norm or not. This does cause me to think of UTG and UTG + 1 as "early position", UTG + 2 and the LoJack as "middle position" and the hijack, cutoff, and button as late position.
If it weren't a kill game though, or even if you just didn't have the leg, I'd be OK with the call here pre flop. I wouldn't 3 bet it though. Having the leg is a strong enough pressure toward making it a fold though.
I was hoping someone would catch on to why this is important, well done. Hero did consider this, but ultimately decided that UTG probably being so wide, this is still worth the call. Against a villian that is only raising 10-15% UTG, I agree this is a fold.
I'm folding kj in EP to a raise to but as played your logic is contradictory and flawed.
Villian is tilty and raising wide so you want to play him but you only call because you want to win a big pot - so you don't actually want to play him but rather all the others yet to come in behind you, but you are in EP so you don't even know how big the pot will be. WTF?
Let me see if I can explain the reasoning better. If hero goes 3 bets here, he can only really expect action from a pretty nitty range of hands, say AK, and TT+. If hero flats, he can expect action from something more like 55+, AT+, A8s+, KTs+, QJs-76s. So the raise knocks out the wrong kind of hands to build a pot. By flatting a few hands that are marginally better get in (the KQ and AQ you mention in the later post, for examples), but far more hands that are worse or at least netural to the plan of flopping big come in as well.
KJs is a sucker hand in limit poker. More so out of position. More so in a raised pot.
I would strongly challenge this statement in general, although I agree with a fold in this particular hand. I've certainly made a lot of money playing KJs over the years in LHE. If you aren't making these kinds of hands work for you, you've got some leaks post flop that could be addressed.
I agree with Rainman on this one, in limit you aren't going to get stacked over a bad kicker. The key is learning how to get away from the right flops when you make middle pair or even sometimes top pair against heavy action.
Okay on with the story.
I appreciate both sides of this decision, and I do think it was close, but
@Gobbs has hit on the deciding factor.
Definitely try to see a free card post-flop and check. If I read right, there are still two to act and you don’t want to see a re-raise (or a raise).
Hero checks and the the remaining two players check as well.
So the 12 small bets are now 6 big bets heading to the turn. (Since the rake was mentioned, it's 5% up to $4 to the reg drop and $2 on a $15 pot to the promo drop, this hand will be the max of $6)
Turn:


Small Blind Checks, Big Blind Bets, UTG Folds (Really how wide is UTG that he doesn't even have a piece of this?), Hero?
