QJ suey from C/O. Is this river decision easy?

[Harv72b]

Based on the reads this is a call & hope for overcall situation. Against bad opponents I would usually raise & call a 3bet.

I'm really puzzled about EP2's range here--that K[img]/images/graemlins/diamond.gif[/img] was a pretty scary card to fall on the river, and it's hard to come up with non-flush hands that EP2 could have here & bet with. AT basically sums it up, or possibly a slowplayed set. I think a weak ace check/calls, and there aren't any other missed draws for him to be bluffing with.
