Donk cbet 46% (13).

Never sure how to play the spots. Feel like if we raise the donk villain is only shipping his sets... when he checks the turn to us, I guess we have to bet since some of his range is flush draws and we need to protect. should I bet a little more? Presumably we plan to fold if he check/shoves without reads?

on the River he thought for quite a while and then lead for 1/2p. looks a lot like a flush... anyone want to call for these odds?
