Final Pot: t5795

Background: The player in the small blind had been miniraising my blinds since the table went six handed and the blinds were sizeable enough that it was worth his time. We had all been stealing and I had built most of my stack through two showdowns - showing AK and QQ. I figured he has some reason to fold here as he would have two blind free hands if he folded and he and the current UTG would be dead even. His pot odds are great (3:1) to make this call so I was hesitant to push back and I wouldn't have called a push off the bat. If that was my thinking does it make any sense to push at him?
