200NL Bodog
Effective stacks=$200
Hero is a 17/8 and the villain is a 50/20/2
UTG limps, Villain raises to $7 and Hero calls on the button with 5 [img]/images/graemlins/heart.gif[/img]6 [img]/images/graemlins/heart.gif[/img]. UTG calls. Flop is 3 [img]/images/graemlins/heart.gif[/img]9 [img]/images/graemlins/heart.gif[/img]K [img]/images/graemlins/heart.gif[/img]. UTG checks and Villain bets $20. What is my plan? Do you shove here or make a PSB. Hero raises to $70. UTG folds and villain calls. Turn is J [img]/images/graemlins/heart.gif[/img]. Villain checks. Hero? I'm mostly concerned with the flop play. Is shoving more +EV because it doesn't put me in this awful turn spot, even though Villain may not call the shove?
