3/6 Online. Did villain improve on the turn ?

[NevadaKaz]

Villain had previously led at a paired boared, he folded the river on that occassion.

UTG limper was terrible, calls down with UI Kings. Makes terrible three bet bluffs.

Now this,

Preflop: Hero is in the CO with T [img]/images/graemlins/diamond.gif[/img] A [img]/images/graemlins/club.gif[/img]

NetMadMax, 1 fold, Hero raises, 1 fold, roby68 calls from BB, moemoe2121 3, NetMadMax 3.

Flop (8 SB) A [img]/images/graemlins/spade.gif[/img] 4 [img]/images/graemlins/heart.gif[/img] A [img]/images/graemlins/diamond.gif[/img]
roby68 bets, 2 folds, Hero raises, roby68 calls.

Turn (6 BB) 8 [img]/images/graemlins/club.gif[/img]
roby68 bets, Hero raises , roby68 3 bets, Hero calls.

River (12 BB) 6 [img]/images/graemlins/club.gif[/img]
roby68 checks, Hero checks

After the aggression on the turn, I felt like Villain was going for c/r.
