AKo blind defense

[SteveY]

maybe this is an easy hand. but i guess i am rusty.

Button is loose pre, with some open limps and coldcalls. But i dunno about his raising standards. Post: he donkbets pretty liberally, but has shown decent hands. it doesnt apply in this hand but maybe it describes the kind of player he is.

just wondering if the turn/river line makes sense.

also if I hadnt hit the ace on the turn should I check/call down hoping for AQ/AT. it seems pretty thin.
