An interesting spot

[brettbrettr]

online $15-30 game, I raise in MP with A [img]/images/graemlins/spade.gif[/img]K [img]/images/graemlins/spade.gif[/img], laggy CO calls, loose, passive, extremely straightforward BB 3-bets, I cap, Lag calls, BB calls.

3 to the flop for 12.5 sbs: Q [img]/images/graemlins/spade.gif[/img]T [img]/images/graemlins/club.gif[/img]4 [img]/images/graemlins/club.gif[/img].

BB checks, I bet, Lag folds, BB raises.

Now, folding is out, but what do we think if our options here. If you want to call say why its better than raising, if you would. If you want to raise, please say why.
