Mathematically, 72o is the worst starting hand because it has the lowest equity and cannot make a straight without using both cards. However, in my view, hands like A2o or K5o can often be much worse trap hands for beginners. With 72o, it’s an easy and instant fold, so you don't lose any chips. But when you hit a weak Ace on the flop with a bad kicker, it's very easy to get into trouble and lose a massive pot to a dominant kicker. So for me, weak unsuited Aces are the real nightmare!
