Reads on villain: seems pretty solid but have seen some bluffs lately

Players:

hero was dealt: 8[img]/images/graemlins/heart.gif[/img] - 9[img]/images/graemlins/club.gif[/img]
2 players fold; btn Call; hero Call; villain Check

Flop (€0.6, 3 players) 9[img]/images/graemlins/spade.gif[/img] - 6[img]/images/graemlins/heart.gif[/img] - 2[img]/images/graemlins/spade.gif[/img]
hero Bet (0,32); villain Call; btn Fold

- is flop bet a bit on the light side? Maybe I should bet 0.45 (75%) if I decide to bet?

Turn (€1.24, 2 players) 8[img]/images/graemlins/club.gif[/img]
hero Bet (0,95); villain Raise (3,00); hero Call (2,05)

- Great two pair against a random hand! What, I'm getting raised alot. Overpair? TPTK? Another two pair? Set? Straight? Bluff?
I don't know if I'm ahead or behind so I call to see the river.

River (€7.24, 2 players) 3[img]/images/graemlins/club.gif[/img]
hero Check; villain Bet (3,75); hero Call

- bah, another big bet. Probably not a bluff then. I'm not happy about the river bet. But I have top two pair so I call and pray to the gods.

What does villain have and what are your opinions on the play?
