I know this guy is getting mad because 2 orbits ago he 3-bet shoved against my button raise. I flop the nuts, but those are the worst turn and river cards I could imagine. How would you guys play flop and turn and would you call the river shove?</font>

How did you flop the nuts? (76 is the nuts).

I'd check behind on the turn and call anything less than $30 on the river and fold for anything more than that.

Given the fact that he donk bet into you and then called your raise, he could easily have a draw (something with a 2, 6, or spades). I doubt he donk bets a set, but I wouldn't rule it out given he cold called from the BB (for me, that usually means a pair that i'm playing for set value).

Given turn and river action, I think you are beat by most of his range. Instead of betting the turn, I check behind and call a smallish to medium bet.
