But why would you fold to worse hands on the river at all!!!111oneoneonecos(0) That wouldn't be +EV!
Sorry wut? I am not folding to a hand he might or might not have, I am folding to a range that crushes me.

"Exceptionally exploitable" would mean something close to folding the non nuts every time we are raised. Seems to me our two pairs, even if they are the top of our range, is very far from the nuts and way behind the range of villain when he shoves spade river. Surely, there are better spots to make balance plays.
