Is this a spot to donk(he's never folds to a cb but I don't have stats when facing donk bet)? I feel calling the raise is fine because he's bound to have a lot of j8 or air type hands that raise my silly looking donk. Can I call a turn bet here?

nh wp. i prefer c/c flop instead of b/c, but other than that nh. (i might 3b though since he min'ed a button)

I like the donk, just because so many players will raise a donk with air. Otherwise you got as much value as you could.
