77 Button

[AUSTIN]

20/40 live, I am on the button and find 77. All fold to hijack and he raises. Villian is very young kid mostly TAG, but can be pushed off of hands. I have seen him make some big laydowns. He thinks he is the best player in the building but can be ABC. He most likely isn't a loser in the game. We have played twice before and I have seen him wait until the turn to raise overpairs several times.
Range:
A8s,A9s,A10s,...
A10o,AJo,...
KQ and 55 or better.
I call on button with 77 and BB calls.

3 to flop (3.5BB)

BB checks, Villian Bets, I... raise?
BB folds, Villian asks "are you overplaying your hand?", stares me down and calls. I sense he indeed holds a monster at this point and is looking to checkraise the turn.

he checks, I bet, he checkraises, I 3 bet, he calls.
He does not show but makes it clear he had me beat by uttering some EV comment and calls me a donkey.

Comments on all streets appreciated.
