[11t]

No particular reads but deductive reasoning led me to believe he had nothing.

Blinds are 50/100

Relevant Stacks:

SB with t1820
Hero in BB with t1370
and T [img]/images/graemlins/heart.gif[/img]8 [img]/images/graemlins/diamond.gif[/img]

Folds to SB who completes, Hero checks

Flop is Q [img]/images/graemlins/heart.gif[/img]A [img]/images/graemlins/heart.gif[/img]5 [img]/images/graemlins/heart.gif[/img]

check, check

Turn is 4 [img]/images/graemlins/spade.gif[/img]

check, check

River is 8 [img]/images/graemlins/heart.gif[/img] pot is 200

SB bets 300, Hero calls

FPS?
