AJs in 3 bet pot - a flop bluff shove vs a TAG

[cs3]

<font color="blue">first time ive played with villain but he has been TAGgy so far, proabbly 2p2. He has been 3betting a ton and playing pretty aggro overall. he was running ~19/17/5 over 120ish hands. this is the 4th time hes 3bet my steal attempt from his sb/bb - i folded PF twice, and shoved AK PF the other time and he folded. he showed down a hand earlier where he 3 bet an UTG raise with 99 and then c-bet an AQX flop for 2/3 pot, then checked down the turn and river. </font>
