Should I have called this on a $33?

[SammyKid11]

Um...don't the results of the hand answer this question for you? You're behind TWO other pocket pairs preflop here. The fact that a 7 happened to flop this time is totally irrelevant to the proper play. You want all your money in when you believe yourself to have the BEST hand, not when you have a hand that you must get incredibly lucky to win with.

Why are you asking this question? For that matter, why are you playing the 33's if you have to ask this question? For that matter, if you have to ask this question...it's time to start over in poker. Read TOP, post here in response to hands, don't play for awhile...then go back to it when you have a more solid grasp of fundamental play.
