Weird preflop checkup

[fivesense]

Been quite a while since i found myself in a tough spot preflop. Thought this was kinda interesting but who knows.

Canterbury 30-60
Game is very good. Most players are just in town for a series of tournements and are of no real threat limit poker wise.
UTG in this hand usually plays 15-30 and is out of his confort zone. I've definatly sensed he's playing tight and borderline "scared".
UTG+1 bad passive fishy player. Loser in the game and not important to note.

UTG opens, UTG+1 coldcalls, you look down at 8 [img]/images/graemlins/spade.gif[/img] 8 [img]/images/graemlins/club.gif[/img] , with what frequency are we three beating here? How bad, if at all, is just coldcalling in the anticipation of winning a huge pot if you flop a set.

Some things to consider: Game is bad enough where calling three cold may not be that big of an obstacle to 2-3 players behind us.
Players in this game are bad enough that coldcalling really wont translate into a hand range to them-they are thinking about their own cards far more than yours.
UTG's hand range is gonna be pretty tight but definalty includes AQs, AKs, AKos, AQos along with the regualr monsters.
Even if we are behind UTG theres a good chance we can control the amount of bets he puts in if we are behind i.e. he will shut down pretty quickly when shown strength.

Anyways probably not life or death either way but i'd like to hear some thoughts on it. Thanks a bunch
