I would check call. You've got 3 people in the hand with a 4 straight as well as the nut straight (Q/J). Those people all called 2 cold preflopo. Your hand is behind to A/K, K/Q, Q/J, K/10 and as of the river any hand with an 8. You also chop with any other K/J. If it's raised are you planning on calling? I dont see how you can call or want to call if the river is raised here.

I just saw your post above mine. Like I said I can't see how you call a raise here. All you beat is a pure bluff. There are too many legitimate hands that are raising this river for you to think your K/J is good here. That's why I don't see how this is an easy bet.
