Villain 1: To my direct right, hes on mad tilt from me 3 betting him light in the small blind and stacking him a couple hands ago after exploiting his 100% button open lolz. $350

Villain 2: Sort of a new player at the table, kinda spewy?...called off his stack on a flush draw and lost to Ace high. It could've been a combo draw too but I didn't pay close attention to the hand.$300

Hero: Was very loose aggressive before stacking villain one. Tightened up my range afterwards because of an awkward showdown...table dynamics definitely got a little weird afterwards. Plus I get action every time I play a hand. $1100

Villain 1 opens to $21 UTG+2
I pick up KK and elect to flat.
Folds around to Villain 2 on the button who also flats.

Flop: JT6ss $61 with -rake
Villain 1 checks
I lead with 40
Villain 2 raises to 100
Villain 1 folds and I flat...

Looking back I should have GII here. I was seriously afraid of the 9(?) combos of JT because villain called the 21$ preflop and the standard open was around 12-15. I can only see JT or AJ raising this flop and maybe AJ would have raised pre. 66 might raise the flop too. And again, I don't have too much history with this villain. Anyways onto the turn...

Turn: 6 $261
I check
Villain 2 bets $140
Hero???

Preflop and every street was played horrible so far. 3 bet pre especially given that he is steaming.

When V2 stacked off earlier with his flush draw, was he the aggressor or the caller?

That would be really helpful to know here.

He was the caller

Thanks for reminding me....thats why I'm having a hard time making a decision. I just flatted hoping he will hang himself with the betting and my preflop 3bets have been getting tons of respect and I still get tons of action in non 3bet pots. Maybe I should've added that too? Idk

I don't mind the flat preflop sometimes. This is part of mixing it up. On the turn, though, I would raise. too many draws to let him see a free card.

As someone who probably slowplays big pairs more than most people in this forum, this is a bad spot to slowplay a big pair before the flop. It makes sense just calling if you have a reasonable expectation that there will be a raise behind you (and the ability to play well when that raise doesn't happen). It makes sense if you are unlikely to get a caller behind you and the raiser is an aggressive player who will bluff multiple streets. Neither seems true here.

My bad guys I screwed up the turn card. It should have been a 4

Errr...how do i edit?
