I have no read on Villain. He has not shown down a hand yet since being at the table and has not been involved in many hands. I have been playing pretty tight, the only hand I have shown down is top set against someone else's overpair and K9o in the big blind on a flop of QJ10.
Preflop: Hero is MP3 with K[img]/images/graemlins/spade.gif[/img], K[img]/images/graemlins/heart.gif[/img].
<font color="#666666">2 folds</font>, MP1 calls $0.50, <font color="#666666">1 fold</font>, <font color="#CC3333">Hero raises to $2</font>, <font color="#666666">4 folds</font>, MP1 calls $1.50.

Flop: ($4.75) 3[img]/images/graemlins/club.gif[/img], 5[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
MP1 checks, <font color="#CC3333">Hero bets $3</font>, MP1 calls $3.

Villain makes a quick check to me, I bet $3 and he calls very quickly.

Turn: ($10.75) 6[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
MP1 checks, <font color="#CC3333">Hero bets $9</font>, <font color="#CC3333">MP1 raises to $18</font>, Hero calls $9.

Here he makes a quick check to me again, and I bet about the size of the pot, letting him know I have a hand and wasn't make a continuation bet with AK, AJ, etc. His minimum raise was immediate and I decided to just call and see what developed on the river.

River: ($46.75) T[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">MP1 bets $85.9 (All-In)</font>, Hero folds.

His bet was immediate.
Final Pot: $132.65
