Villian has 650 and I have him covered. 6max. I have a lag image. Villian hasnt done anything stupid so far.

Hero is UTG with 7[img]/images/graemlins/club.gif[/img] 8[img]/images/graemlins/club.gif[/img]

Hero raises to $24, all fold to villian (BB) who calls.

Flop comes: A[img]/images/graemlins/club.gif[/img] K[img]/images/graemlins/spade.gif[/img] 3[img]/images/graemlins/diamond.gif[/img] (pot = 51)

Villian checks, Hero bets $40, Villian calls.

Turn comes: 4[img]/images/graemlins/club.gif[/img] (pot = 131)

Villian checks, Hero?
