[Zoe's Echo]

Pokerstars $0.10/$0.25 PL - I am on button with $46 one player at the table has me covered at $73. UTG limps, big stack limps folded to the Button (hero) with AKo - I raise pot UTG flat calls, Big Stack raises pot. I call.

Flop A 6 5 - UTG checks - Big Stack bets pot.

What's my move? - For some background - I had oberved this player slow play big pairs before at this table.
