NL400 - AK hits flop and gets CR'd on turn

[Janabis]

Villain is about 33 / 10. A little loose but not too crazy. My image is very tight so far and this leads me to believe he might be trying to bluff at it. I think I bet too little on the flop, but what do you do after that?

Flop : I bet a bit more, 25-36

Turn : I probably bet 1/2 pot. I guess calling the checkraise given your betsizes and your read can be ok.

River : Easy fold, you only beat him if he had complete air on all three streets.

Flop: $30-$36

Turn: $65-$70 (and be ready to fold to a substantial raise)

I feel you should end the decision making for this hand on the Turn. Either you fold (on Turn) or jam and go to showdown. I don't think any decisions should be made on the river with AKo in this hand and given the said community cards.

Based on the way you played it - fold river. I think you set him up nicely to either hit whatever he may have been chasing or you allowed him to set up a good bluff.
