10's vs a solid player

[HollywoodDB]

This is from a live 32-man tourney. $20.00 buy in. There are about 18 people left. Top 3 pays.

The villian has only been at our table a few rounds. No huge reads other than he seems to be pretty descent.

Hero is UTG+1 with 10 [img]/images/graemlins/diamond.gif[/img] 10 [img]/images/graemlins/heart.gif[/img]($45.00)
Villian is UTG+2 with about ($37.00)
Average stack is around $50+ or so

Blinds are 1/2

PRE:
UTG mucks, Hero raises 4 making it 6 to call. Villian raises 20. Everyone folds to Hero.
Hero...?

Is this an auto fold? My thought was, why would villian make such a large bet with a higher PP. Smells like an isolation bet to me with a smaller pair putting me on a high Ace. What do you guys think?
