djames I agree that it would take some serious nuts to fold the river for one bet. I'm not sure if I could do it in that spot, but a river 3-bet is pretty damn good sign of strength.

If he has KK-TT, the turn bet he put in is costing him money because he's only drawing to two outs. So even though you let him see the river card, you're still making +EV. If you raise, he folds, and you don't win any more.

Do you think he still has AK-AQ on a flop check-raise 3-bet? There's only 1 combo of AA, so you're looking at KK-TT most of the time, so you want to optimize your play for those hands.
