Preflop: Hero is CO with 5[img]/images/graemlins/heart.gif[/img], 5[img]/images/graemlins/diamond.gif[/img]. Hero posts a blind of $0.25.
<font color="#CC3333">UTG raises to $0.75</font>, <font color="#666666">1 fold</font>, <font color="#CC3333">MP2 raises to $1.25</font>, Hero (poster) calls $1, <font color="#666666">3 folds</font>, UTG calls $0.50.

We have to assume UTG has some kind of hand if he comes in for a raise. For MP2 to three-bet narrows his range to JJ+, maybe AK. I call because MP2 has a nice stack. What does it say about UTG that he just smooth calls the three-bet? I figure he's got two big cards like AK or AQ, a medium pair like TT or JJ, or he's slowplaying AA or KK. But a good player with AA or KK would have re-reraised after my overcall to try to see the flop head's up, wouldn't he?

Flop: ($4.10) 5[img]/images/graemlins/spade.gif[/img], 3[img]/images/graemlins/club.gif[/img], 8[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(3 players)</font>

This flop is very good for me, since it's unlikely to have hit either of my opponents. At this point I want to get as much of both my opponent's money in the pot as I can.

<font color="#CC3333">UTG bets $0.25</font>, <font color="#CC3333">MP2 raises to $2</font>, Hero calls $2, UTG calls $1.75.

Despite the raise, MP2 isn't betting much money. At some point I'm going to have to raise him if I want all the money to get in the middle.

Turn: ($10.10) Q[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(3 players)</font>

This is a scare card for me, since QQ is solidly in MP2's three-bet range. Suddenly I'm WA/WB.

UTG checks, <font color="#CC3333">MP2 bets $1</font>, Hero calls $1, UTG calls $1.

Another weak bet from MP2, but now I don't know if I can afford to re-raise. But I'm not folding unless one of them pulls out a gun.

River: ($13.10) 6[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(3 players)</font>
UTG checks, <font color="#CC3333">MP2 bets $1</font>, Hero calls $1, UTG folds.

Final Pot: $15.10

Should I have raised the river?
