Flop: (t150) 9[img]/images/graemlins/diamond.gif[/img], 8[img]/images/graemlins/club.gif[/img], Q[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(3 players)</font>
SB checks, <font color="#CC3333">BB bets t150</font>, Hero folds, SB folds.

Final Pot: t300

My thinking behind the hand was this:

ATs 5 handed is too good to fold, not good enough to call a raise. The blinds were small enough in proportion to my stack where a push wouldn't be worth the risk, yet my stack was too small to be able to withstand folding after a raise.

If I raise and am called, I could be playing a dominated hand out of position.

So I limped.

Weak/tight?
