A 30r hand by Mikej with an interesting flop decesion

[Bond18]

Doing a review with mikej right now of his afternoon tilt 30r final table. This hand is deep, near the FT bubble, and this hand came up which i really am not sure what the best line is post flop.

Mike has been fairly aggressive but by no means overly so, i think this is first time villain has called him in position.

Stacks:
Hero: 40,600
button: 66,400
BB: 34,900

Blinds 800/1600 with 200 ante, 5 handed.
Hero holds J [img]/images/graemlins/diamond.gif[/img] T [img]/images/graemlins/diamond.gif[/img]

Preflop: UTG folds, hero raises to 4200, button calls, SB folds, BB calls.

Flop: A [img]/images/graemlins/diamond.gif[/img] Q [img]/images/graemlins/diamond.gif[/img] J [img]/images/graemlins/club.gif[/img] (Pot 14,400)
BB checks, hero?

Best line?
