3bet AK OOP

[Sardine]

I've only seen MP villain a few orbits, he seems decently aggressive.

With AK UI OOP on the flop, could we push? The flop is relatively safer for us since sets are less likely than if board had middling cards. Many players would fold 33's and 55's to 3bet pre, but call 66-TT. JJ or QQ might reraise? KK and AA would reraise pre most of the time so less likely. So push first to act or is C/F standard vs unknown?
