Halv: No evidence that he's a calling station, just loose/passive pre and possibly on the flop. I think your average fish folds pp's lower than 8, 4's, missed overs and some flush draws to a second barrel. Stacks are 100bb deep, plenty deep for a 3 barrel bluff. In fact, I kind of like 2/3 on the turn and if he calls, shoving any non-diamond river.

Fnord: I think you can fold to a turn c/r shove, but you're right that if he c/minraises, it's an easy call.
