Preflop: Hero is BB with A[img]/images/graemlins/diamond.gif[/img], Q[img]/images/graemlins/heart.gif[/img].
<font color="#666666">1 fold</font>, <font color="#CC3333">UTG+1 raises to t3600</font>, <font color="#666666">6 folds</font>, Hero calls t2400.

This hand was during the 500k Guarenteed at Stars. Only read on UTG+1 is that he is a horrible player. Too loose with his calls and doesn't understand position or any other poker theory for that matter. An all around donk.

I posted this in the 500k and was told the move was incorrect and I should have pushed preflop. After reading through the anthology (Raymer's Stop and Go Post), I feel that this is the exact spot I want to use the stop and go. I'm willing to go broke here and I'm not folding this hand, if I push here he has to call but I may get him to fold the better hand if a scary flop hits.

I am reposting it to see what people feel. I will post the results after seeing what the general feeling is without them.
