Doh - a little late to the party but ...

Given that his line looks a lot like KsKx to me too, wouldn't the most callable river bets by you be either a $4-$6 range or a push?
Even with a push he'd have to assume you were bluffing roughly 50% of the time to be profitable is that right?

Your line appears to me to be one of JJ, AJ, 89s/9Ts or a 1-pair bluff to me but I don't think I can assign a 50% or even a 30% to the bluff so I don't think KK can normally call there.

Would a bet right around $8 range be less likely to be called than the push (which looks like either a bluff or a fake bluff)?
