AJo HU on ABS 2/4

[Somekid]

Lately I've been trying to improve my heads-up skills. I was wondering if the hand here is appropriate to call down after the c/r. If it isn't appropriate against this player, what kind of player should I do it against? Also, is the turn bet standard?

Villain: 41/12/1.56 through 68 hands

I raise, Villain calls

Flop:Kc 3d 6d
Villain checks, I bet, Villain calls.

Turn: Ks

River: 2c
Villain bets, I call.
