Both these opponents are LPPish callingstation 50/10/1 types, however they seem to always bet when you show weakness. They will almost never bluff-raise turn.

Preflop: Hero is BB with A[img]/images/graemlins/heart.gif[/img], J[img]/images/graemlins/club.gif[/img].
<font color="#666666">1 fold</font>, MP calls, CO calls, <font color="#666666">2 folds</font>, <font color="#CC3333">Hero raises</font>, MP calls, CO calls.

Flop: (6.40 SB) Q[img]/images/graemlins/club.gif[/img], 8[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(3 players)</font>
<font color="#CC3333">Hero bets</font>, MP calls, CO calls.

Turn: (4.70 BB) 6[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(3 players)</font>
Hero checks and folds.

This is my standard play...Do you ever fire a second barrel ? How about if the turn is another 8?
