AKo against an ultra-tight UTG raise

[Roland19]

If we three bet, the preflop raiser is going to cap with those hands that have us seriously in trouble, and just call with all other hands (AK, JJ, QQ, 10s maybe), which gives us more information about his hand, which will lead us to make better decisions on later streets. Also, I think it's good to have him isolated, and three betting certainly increases these chances. How flawed is my thinking?
