(Party 5/10) AA Turn Line

[cardcore]

Villain is psykotow (21/17/3.48).

In like 5000 Hands I've never seen him donking the flop against me, because he always "checked to the raiser", so this was confusing me a little bit. He doesn't get out of line often, but can be a tricky player in some situation and likes to make herocalls. He seldom makes moves with total air.
