UTG is a 28/12/1.5 player over 73 hands. The only specific note I have on him is that he raised 46s UTG once, but I pegged that as "I'm bored" play. Should I expect A[img]/images/graemlins/club.gif[/img]5[img]/images/graemlins/club.gif[/img] or a set that was resisting a turn raise?

I can't put him on a hand that bluffs.
