Blind battle with bp

[Fadook]

Sorry if this is obvious, but I suck at playing heads-up against these super-loose people.

Only played 39 hands with Villain, 69/7/1.93. Quite aggressive, he's bet 9[img]/images/graemlins/club.gif[/img]2[img]/images/graemlins/spade.gif[/img] on a 9[img]/images/graemlins/heart.gif[/img]T[img]/images/graemlins/heart.gif[/img]J[img]/images/graemlins/spade.gif[/img]8[img]/images/graemlins/diamond.gif[/img] board on the flop and turn heads up, bet K hi on an AAxx board on flop and turn, and other such stuff. So far he's only bet the river or raised anywhere with strong hands.

Should I have bet the turn? Is the river an easy bet?
