OK, I zapped in my post and I didn't realize it is 6max. This makes UTG's range def. wider than 99+,AQ+. Say 10% of hands, which is really tight for 6max: 88+,ATs+,KTs+,QJs,AJo+
I still think 3b is a good play, esp. if you have a decently high 3b% like 7+ and some history with opp.
c/c + lead turn is an interesting line. Would you lead any turn?
