Making a player read based on things the player has done this hand

[einbert]

Pacific Poker 10/20 6max. Somewhat loose game but most players are reasonable and not stupid.

The button is almost totally unknown, but I do have some information about him. I have only seen him play one hand out of several, and in that hand he called a raise from the BB and check/folded a flop with an A on it.

Folded to me in the CO and I raise K[img]/images/graemlins/spade.gif[/img]T[img]/images/graemlins/club.gif[/img], button who is unknown coldcalls, blinds fold

2 to the flop
Flop: (5.3 SB) Q[img]/images/graemlins/diamond.gif[/img] Q[img]/images/graemlins/heart.gif[/img] 9[img]/images/graemlins/club.gif[/img]
I bet, button calls

Turn: (3.65 BB) 2[img]/images/graemlins/spade.gif[/img]
I check, button bets, I call.

River: (5.65BB) K[img]/images/graemlins/club.gif[/img]
I bet, button raises, I fold.

Thoughts on all streets appreciated.
