Hello All,

A friend played this hand and disagrees with what I had to say about it, so asked me to post it here.

2nd hour

BB= 200

Hero=2800 in LP
Villian= 4200 in BB

Folded to Hero with A [img]/images/graemlins/club.gif[/img]Q [img]/images/graemlins/diamond.gif[/img], raises to 500 to go

Folded to BB, flat calls

Flop (1100) comes Q [img]/images/graemlins/heart.gif[/img]4 [img]/images/graemlins/heart.gif[/img]7 [img]/images/graemlins/heart.gif[/img]

Hero lead 800 at the pot, Villain flat calls

Turn (2700) : 6 [img]/images/graemlins/club.gif[/img]

Hero has 1500 left.
What should Hero do and why?

Regards,
Woodguy
