Do you like my line here? I think I had to call that raise, so I'm thinking I should have just pushed in first. I think this maybe a standard play, but I was wondering if anyone else plays it any differently. I figured I would have a race at the best, but as you know you have to win these kind of hands to win these large tourneys. So's what's everyone think?

This is a good push from UTG, but a call here is also almost automatic. Bad players will push with a lot less than AQ, especially if you've been raising a fair bit. Any reads on BB?

nope, he just moved here, the table overall was fairly tight though

[Exitonly]

yea. push to start. but since you didnt, oh well think you gotta call now.

Push. You're pot committed with your raise to begin with.
I see few realistic scenarios where you'll fold after raising. Pushing is the most powerful play.

Unless he's holding exactly AA, KK, QQ or AK you're getting the right odds to call. With no reads this is a tough call but I think you have to make it. There's a decent likelihood of this being a lower pair, a lesser Ace or complete air. If this is a true "resteal" you should be golden here.
