The reason why I hate it from start to finish (literally not a single street I like) is also you say you want to 3bet THIS hand to "establish a dynamic". Why the hell do you want to establish a dynamic when a tight player opens UTG? The cost of that dynamic is just too great here. It seems you're fluidic in your 3bet frequencies, which is fine, but even outside of a vacuum this is a poor spot to 3bet.

About the flop, you say you wanted to bet bigger, and imo (to borrow from Aaron) villains calling range, especially when he's straightforward, is fairly inelastic. So, the sizing of your bet shouldn't change MUCH - if he has AK (he may 4bet it pre anyway) he's mucking, same with AQ (although he may fold that pre). If he has an overpair, he's c/c the flop, unless he's c/r. Again, since he likely has a decent range, and the only stuff he prolly will c/f will be like KQ with no outs, i'd just check behind and hope to bink a straight.

As noted, 7 helps him more than you (in his straightforward perceived range, atleast), so a 2nd barrel here is only to knock him off a weak overpair... which isn't the best idea in general, but you didn't even mention he was weak tight. many std tags are fishy in their hero tendencies, most would c/c down with an overpair.

Hopefully that sums that one up/
