What would you do?

[95Aero]

15 people left in a 300-entry poker tournament, NL Hold'em.

Hero is on button with 12000 chips, others range from 5-40000 in chips.

UTG limps in with blinds at 1600, everyone folds to Hero who raise, around 3000 with A9s, BB re-raises 3000, UTG and Hero calls.

Flop is A47 where 47 is of same suit as hero.

BB goes all in.... UTG goes all in....

Hero does what?

(BB and UTG initially had around 11-13000 chips each)
