One player limps from EP, I raise from MP with A[img]/images/graemlins/diamond.gif[/img] J[img]/images/graemlins/heart.gif[/img] and everyone folds to the limper who calls....

Flop comes: 7[img]/images/graemlins/spade.gif[/img] 2[img]/images/graemlins/spade.gif[/img] T[img]/images/graemlins/heart.gif[/img]

And the opponent bets into me....
How often is he on a draw?
How often does he have a pair?
Should I raise him for a freecard?
Should I raise him and bet the rest of the hand?
Should I just call him and fold turn if unimproved?

How do YOU act in these situations?
