I dont think he's donking here with a draw. Fish tend to do this with any top pair, but since he's unknown, who knows. The size of the bet certainly gives the impression that he has a made hand to protect.

I think I'm raising to 15ish and folding to a push. Depending on how bad he is you might get value from KJ/QJ/J10. If he pushes its safe to say he has 33, 55, AJd, AK/AQd, maybe even A2d or A4d if he's a fish. More likely a set tho.
