I already smelled trouble coming in with JK..
The Flop was decent enough, SB does have a big range and the flop wasn't ideal... Nevertheless i thought a CBET was protocol. When SB raises here I smell trouble... I call to see his action on turn... He pulls trigger.. And there are so many possibilities...
I'd like to hear some analyses of the hand...
Maybe a Check on Flop or Good until Turn N FOLD?
Or Good all the way and Call the Turn.

Why do you smell trouble? You have KJs in a blind battle in position vs a villain who limp-called your raise, you are golden.

I'm assuming your readless since you didn't post a read, nor your image.

Pre Flop is good,

Flop is good,

Once you call the turn, and this blank river comes, you pretty much have to call the river when readless. Nothing changed on the turn, so call. At this buy in people will show up with alot of BS, plus you're getting slightly better than 2-1.

Another thing that sways me toward calling is that the villain min-raises the flop, but shoves for pot on the turn. He's telling you that he's milking you on the flop, so why is he pot shoving the turn?
