With a stack so low, I don't really have a position advantage anymore, but I do have special hand strength with hole cards like 97s, 68s, 56os, T9, 89, even 45 if I am that low on chips. The reason these hands have hidden strength is because they are rarely dominated by a pre-flop raiser. Compare hands like AJ, KQ, KT, QJ and Ax, where you are much more likely to be a 4 to 1 underdog to win. Then take a hand like 87s and you are just a slight underdog with a hand like AJos!
