Preflop: I don't have an overcalling range here multiway when I'm not playing IP. So I'm playing JJ is a pure 4bet in this spot.

Flop: BB might well have TT here plus low broadway hands that connect well with T8xss. So I do establish a checking range here, but JJ goes into my betting range. We might get some value from an occasional ATs and the incentive for equity denial vs. A-Q is strong. Betsize is low due to low SPR.

Turn: This is where my confusion sets in. So in general we could try to get to showdown now. What do you think about turning my hand into a bluff? Let's assume that quite some of the Ax hands got folded OTF and that we won't get any more value from weaker holdings on the river anyways after a turn check. The very nice property of turning this into a bluff would be that we get most KK-QQ to fold, a tremendous result for my holding. If we get called, we still have 9 outs vs. most holdings.

So checkback and get to showdown or ship this in?
