Flop: (3 SB) 8[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/spade.gif[/img], 4[img]/images/graemlins/diamond.gif[/img] <font color="blue">(3 players)</font>
<font color="CC3333">SB bets</font>, <font color="CC3333">Hero raises</font>, UTG calls, SB calls.

Turn: (4.50 BB) 8[img]/images/graemlins/diamond.gif[/img] <font color="blue">(3 players)</font>
SB checks, <font color="CC3333">Hero bets</font>, UTG calls, SB calls.

River: (7.50 BB) 2[img]/images/graemlins/spade.gif[/img] <font color="blue">(3 players)</font>
SB checks, Hero checks, UTG checks.

Final Pot: 7.50 BB
<font color="green">Main Pot: 7.50 BB, between SB, Hero and UTG.</font>

UTG calling two cold gave me the vague impression of chasing a flush since so many people chase it regardless of odds. I planned to check/call the river. Does anyone make a case for betting (folding to a raise?)
