Can check-raising the river on a board like that be +EV with any hand besides the absolute nuts? Remember, DN called fairly easily with the 4th nuts. I'd say there is at least a 50% chance he calls with the 5th nuts, which would be 5-9, 5-8 or 5-6 I believe. 8's full or 9's full is an insta-call.

Even Gus is not c/r-ing with anything less than quads in this situation.

Moreover, DN put in a value bet on the river. No way was his river bet designed to force Hansen to fold. If DN had had an overpair then he either overbets the river representing a monster (to force Hansen to fold a straight or trip fives) or checks it down figuring that Hansen gave up on the river and that he (DN) most likely has the best hand. A value bet when the pot was so huge would be far too tempting for Gus to call. Therefore, Hansen c/r-ing a value bet should signify to DN that Hansen is mother-f**king nutted.

Moreover, if Hansen has either trips, a straight or 5's full and he is putting DN on an overpair then there is no way he check-raises the river. This is value-betting time b/c DN is checking down an overpair in fear of a rivered straight or trips. Additionally, if DN is playing an overpair to the river then pocket 8's has to be a hand that he is putting hansen on. Thusly, the 8 on the river is an action killer for DN and Hansen has got to bet first to extract max value. The c/r erases the possibility that Hansen is putting DN on an overpair.

I'm not saying that it was an easy fold -- no way it was -- but, i think it is a clear fold in retrospect.
