72o is the least potential hand few people play it and it wont get you into too much trouble but the worst hand all variables considered is KJ and probably KT. Why? Because they are the strongest weak hands in the game and their pairs are almost always dominated. KT is a 2 gapper which cannot hit pairs because they get dominated badly by AK and its combos, KQ and its combos, KJ and its combos, AT and combos and AA,KK,QQ,JJ,and TT. Terrible hand good for nothing except shoving all in desperation with 10BB or less it is strong enough to continue the hand but not strong enough to win....bad attribute. KJ i'd say is the worst because it make you think you got two high cards because both are face when in reality J is a middle card.
