Confused with AK

[mute]

CO is 23/14/2 after 200 hands and MP is 55/10/.7. UTG was disconnected preflop.

I have to call this down, right?

Comments on the flop play also appreciated.

Is the turn bet/call so you're not paying a 3-bet and you're trapping the dead MP? I'd often checkraise this, just wondering. I'll get 3-bet by AJ and JJ though.
