TT went well, but how was my thinking?

Final Pot: 11.50 BB

3-bet pf is pretty obvious. An all undercard flop looked good, too. But with the flush draw and straight draw (albeit unlikely) and two more cards to come which could easily carry overs, a bet wasn't protecting me here and it would scarcely be for value. I checked, hoping for it to go around to Button. Since he raised pf, I was hoping he'd raise when it got checked around to him. Lucky me, it did. I raise, knock out two people, and then bet the next two unders.

So, how was this flop logic?
