Strange AQo

[Peter_rus]

My opponent seems average. PFR 9.8%, VPIP 26.64, Hands 214. Agression 0.53, 2.35, 2.75, 3.20. He tends to fold with nothing and also often deeply slowplay his big hands as seen from his agression stats. He able to call down flop with any pair or correct draws. Too weak? What's your plan for turn and river?

Well played.

Really well played. I'm kind of confused about the turn, though... clearly it was the best move to check, but how'd you know to check?
