So I got abused in chat by this (by a moron though, so it's all good). My thinking was that if I check the turn and river, he might bet with his JJ or QQ or AQ or KQ or whatever, whilst if I bet either of them, he's folding. Oh, and UTG is a complete drooler: 80/10/0, dropped $400 in past hour, my proudest buddy list addition for the day.
