A rather nice pot... does anyone disagree with my play up to the river?

Party Poker Pot-Limit Hold'em, $0.50 BB (9 handed)

MP1 ($24)
MP2 ($24.50)
Hero ($61.85)
CO ($35.70)
Button ($41.30)
SB ($17.45)
BB ($19.75)
UTG <font color="purple">(Villain)</font> ($36.25)
UTG+1 ($23.75)

Preflop: Hero is MP3 with 4[img]/images/graemlins/heart.gif[/img], 4[img]/images/graemlins/diamond.gif[/img].
UTG <font color="purple">(Villain)</font> calls $0.50, UTG+1 calls $0.50, MP1 folds, MP2 folds, Hero calls $0.50, CO calls $0.50, Button calls $0.50, SB completes, BB checks.

Flop: ($3.50) 9[img]/images/graemlins/heart.gif[/img], K[img]/images/graemlins/spade.gif[/img], 9[img]/images/graemlins/diamond.gif[/img] <font color="blue">(7 players)</font>
SB checks, BB checks, Villain checks, UTG+1 checks, Hero checks, <font color="CC3333">CO bets $1</font>, Button folds, SB folds, BB folds, Villain calls $1, UTG+1 folds, Hero calls $1.

(At this point I'm sure that somebody has the 9, and I call just on the slight chance that I'll catch my 4 and nail somebody)

Turn: ($6.50) 4[img]/images/graemlins/club.gif[/img] <font color="blue">(3 players)</font>
<font color="CC3333">Villain bets $2</font>, Hero calls $2, CO calls $2.

(Here I cry out to myself "Yes!". Great poker face :-p)

River: ($12.50) 6[img]/images/graemlins/heart.gif[/img] <font color="blue">(3 players)</font>
<font color="CC3333">Villain bets $4</font>, <font color="CC3333">Hero raises to $15</font>, CO folds, Villain calls $11.

Final Pot: $42.50
