10/20, KK v River Checkraise

[JemY]

Pot Odds: 2 to1, we need to win 30% of the time

Would he not c/r a FD with overcards on the flop? If he does have a FD,I wouldn't expect
him to c/r AI river with a busted FD more than 20% of the time. (already a generous number)
Now we need to win another 10% of the time against his range for the call to be breakeven.
There is obviously no hand he is check raising AI for value that you beat.
Do you really expect him to raise 89 AI for value? If he thought he was good he would just
snapcall this, of course. Raising would be stupid since your hand is either an overpair
that's not going to fold a lot, or air that he can now beat.
Same goes with the AJ type-hands that he played previously.
If he thinks ace high is good, he's calling (same explanation as before).
And I don't see how he could be raising 99 or TT here.
There are many hands in his range that have you crushed (67, 78, 54, A2, 88, T9dd) and
really few that you beat (missed flush draw with overcards, for the most part)

To me we don't win here much more than 20-25% of the time. So fold > call
