How do you like my line up to the river, and what's your river move and why?

I cbet the flop.
As played I push, the sample is small but it's obvious opponent sucks and will probably stack off versus a weaker kicker. The fact that he has raised once mkaes AK doubtful and AQ a little douubtful. I don't think he play AT differently than A9.
