Pre-flop: (6 players) Hero is CO with Q[img]/images/graemlins/diamond.gif[/img] Q[img]/images/graemlins/club.gif[/img]
<font color="#cc0000">UTG raises to $1</font>, UTG+1 folds, <font color="#cc0000">Hero raises to $3.75</font>, 2 folds, <font color="#cc0000">BB raises to $6.5</font>, <font color="#cc0000">UTG raises all-in $21.9</font>, Hero ???

Neither player has a full stack and I'm not particularly worried about UTG. I'm doubting BB is 4 betting AK or JJ here. What do you guys do?

They both look very, very strong. This is 50 NL, I never see much 4-bets at all. Without a read I think you have to drop this.
