Hero Folds. Even though this guy is a donk, his AF of 0.74 indicates that he does not bet with nothing. This pot is small. Consider that you will likely have to call a river bet as well; effectively, you are getting only 3:1 pot odds.
A larger pot might swing this decision to a call, but unless you have a specific read that this guy is a habitual bluffer, then this is an easy fold.
