10 10 in the BB, how is my line?

[deaders]

Game is Prima NL$10 10 handed.

Been playing for a few hours at the table and think I have pretty good image, only shown down good hands that I have played aggresively. Villian in this hand (button) is loose and quite fishy having done things like minraising A5o in MP then calling 2 all ins, somehow beating KK and QQ. He makes some strange raises, min raising J5s in EP also, and basically plays a lot of hands.

Stack sizes: I am on about $13, Button is on about $8

Preflop: Hero is dealt 10[img]/images/graemlins/heart.gif[/img] 10[img]/images/graemlins/diamond.gif[/img] in the BB.
Folded to Button who minraises 0.20, SB folds, Hero raises 0.80, Button calls.

Flop: 9[img]/images/graemlins/spade.gif[/img] 3[img]/images/graemlins/club.gif[/img] 3[img]/images/graemlins/spade.gif[/img]
Hero bets 1.40, Button calls.

Turn: 9[img]/images/graemlins/heart.gif[/img]
Hero checks, Button bets 1.50, Hero calls.

River: 5[img]/images/graemlins/club.gif[/img]
Hero bets 2.40...

How did I play it so far, and what would others have done differently? If I get raised on the river I dont see that I can call it, anyone disagree?
