I didn't have much of a read as to what the min raise from UTG could have meant. He wasn't a particularly strong player, but I don't remember ever seeing him min-raise 1st in. He did a lot of limping earlier at the last two tables when he was megastack and wasn't afraid to call big reraises with mediocre holdings like Q8s...

What's my play here?
