AKs 3bet pot flopped A

[HustlerLA]

700 effective stacks. Live 5/5NL, LA casino
I have been raising in position quite a bit and particualrly in teh last few minutes with some SC's and was glad to
find A [img]/images/graemlins/spade.gif[/img]K [img]/images/graemlins/spade.gif[/img] on the button. 2 EP limpers, and folded around to me and I raise to 30. BB young guy very cocky telling people "I shoulda have stacked you in the last hand" several times. I see him as TAG def. not LAG but may be assuming I am raising light. He 3bets from the BB to 105.
Hero? What is standard here, does anyone 4bet? Note: this is live (much less 3betting) and we arent short stacked.
