bb shows A [img]/images/graemlins/club.gif[/img]A [img]/images/graemlins/heart.gif[/img]
mp2 shows Q [img]/images/graemlins/heart.gif[/img]Q [img]/images/graemlins/club.gif[/img]
bb wins $457

at the time i felt pretty good about folding on the turn and saving 3 bb's, but on reflection against these two opponents folding on the turn would be a big mistake over the long run and maybe i should have 3 bet the flop and lead at the turn
