Sorry about spewing in all threads, but I have a new toy I can't resist playing around with.
I played around with the Combonator. Assuming he raises his preflop post with a very tight CO open raise, then assuming he folds trash on the flop, the result becomes surprisingly dominated by trashy made hands on the turn. Edit:I assume too he isn't raising flop with anything. (I assume he'd slowplay what he perceives as monsters, like J9. This goes well together with a poster.)

The given your turn bet, I again removed his complete trash. Resulting river equity 10%.
(Edit: It is still a check-call on the river. He is probably not betting stuff like 4x, 5x, 6x but will be bluffing some.)
