Stars $20 MTT, AJo TPTK flop situation (maybe easy)

[bobbyi]

$20 MTT on Stars. We started with 600 people and at this point we are still pretty early and most of the field is still in.

I had just gotten moved to a new table, so I didn't know the opponents here. The turn fold seems clear here (yes?). My real question is what to do on the flop. Despite having a player behind me, I elected to call to keep the pot size small and because the turn card here will change the value of my hand a lot. Good or no?
