Ok, this hand happens nearly 2 hours into the $22 MiniFTOPS Event #1. I have been at this table for most of the tournament and from what I've seen, the villain is a solid player and has picked up a number of uncontested pots in position. We butt heads twice and he won both times without showdown. I've played TAG for most of the tournament, but did pick up my aggression in the past couple levels and successfully built an above average stack.

I think he is fully capable of of raising me with air here, however his sizing does indicate he's sticking around. What would you gents do?

Appreciate any feedback.
