Preflop: Hero is MP2 with K[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/diamond.gif[/img]. CO posts a blind of $0.35.
<font color="#666666">2 folds</font>, <font color="#CC3333">UTG+2 raises</font>, <font color="#666666">1 fold</font>, <font color="#CC3333">Hero 3-bets</font>, <font color="#666666">1 fold</font>, <font color="#CC3333">CO (poster) caps</font>, <font color="#666666">3 folds</font>, UTG+2 calls, Hero calls.

Did CO get dealt a real hand right out of the gate? What range of hands do you put him on? I felt AA/KK/QQ/AKs all very possible. JJ and TT I guess also possible.

Flop: (13.80 SB) 9[img]/images/graemlins/spade.gif[/img], 5[img]/images/graemlins/diamond.gif[/img], 3[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(3 players)</font>
UTG+2 checks, Hero checks, <font color="#CC3333">CO bets</font>, UTG+2 folds, Hero calls.

I called getting 14.8:1 as Im not ready to abandon my stake in this pot as of yet.

Turn: (7.90 BB) K[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
Hero checks, <font color="#CC3333">CO bets</font>, Hero calls.

I was going to c/r the turn after the K hit but here was what I was thinking in the heat of battle. If he has AA Im drawing slim. If he has KK Im drawing dead but I felt this hand probably not likely. If he has a hand lower than my K's he will be drawing slim and I don't want to lose him. With AK we split.

River: (9.90 BB) 8[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(2 players)</font>
Hero checks, <font color="#CC3333">CO bets</font>, Hero calls.

Thanks for any thoughts on this one.

Final Pot: 11.90 BB
