10nl 6 max - AQo on the button

[Phantom LImb]

i guess this is probably a 3 bet on the button, but just wondering how you guys play this situation. He seems to be betting pretty strong here into 2 players, so just not sure how to decipher between Ax, Set, or flush draw. Villians stats are 26/22 AF 6.0 over 103 hands.
