1: theres more info needed than this. i would call assuming everything is unknown.
2: i dont bet the turn, you dont need to bloat the pot with TP3k here. do you expect him to call you down with QT? i doubt he limps that utg...he probably has AA/KK or 99.
3: i would just fold preflop. 5k is too much...pot will be too big on flop to be able to outplay him
4: the people after you make a big difference in this hand. i would fold this unless i know blinds are really tight.
