Donking madness makes me feel lost.

[Drontier]

Ok, so no reads on the table. On the turn, sb had a very hesitated call. I'm pretty damn sure I'm still ahead on the river, but I figure I'd go for the overcall after the hesitation. But hey, maybe sb will call two cold anyways. Can someone tell me the best way to play this hand?
