calling the allin with A J off suit
well, i try to avoid all in preflops unless i am really strong...AA, KK, AK or AQ.
pocket queens are acceptable too, if you know you can survive the hit if you lose. at best, the call you made was 50/50...and at worst he had solid pocket cards. I often make preflop bets...but if someone goes over the top, i am not married to it if i dont think my hand is that strong. best bet...just fold, you havent lost anything, and wait for a better spot. also, your position was very vulnerable..good luck in the future
