BB is a loos-ish passive-ish typical low stakes fish.

We raise in the CO with 66. BB calls. Flop comes



BB checks to us, we cbet and he calls.

The turn brings the Kd

:Kd:

At his point his range is

a) Lots of drawy stuff that will call a bet.
b) Lots of 78, 9T, 77 type stuff that beats us, but folds to a bet.
c) A relatively small amount of stuff that beats us and never folds.

So if we bet here we are pretty much dividing his range into 2 parts, and we are bluffing the stuff we are behind while getting value from the stuff we are ahead of. Thats a pretty big fundamental theory win for us.
