UTG is very loose playing at 72/54 over 100 hands. Other than that, no real read on him.

Is a check better on the turn or should I continue trying to represent AAxx on the turn after picking up a few more outs with the Q of spades.

My table image is semi tight playing at around 22/10 and I haven't really reraised any hands especially out of position.
