The main crux of the expert's (not that I am one... yet) shortstack strategy is not exploiting fold equity. That idea is ridiculous. You can't force someone to fold for 20bb. Fold Equity is not even remotely "a lot of his edge"

The crux of the strategy is play better cards than the full stacks and let the math sort itself out. We recognize that people stack off lightly against shortstacks, and in that aspect the concept of a shortstack who thinks he can make you fold is laughable at best.

3betting me light preflop is stupid because I'm not raising bad hands preflop. If you're 3betting me preflop, you really should have a premium hand because I'm going loloshoveadoodles a lot, and you can't fold. If you do this with a weaker hand, you're going to be all in with the worst of it, and this makes me money. I think most people realize this, but its the complete opposite of what he states in that thread.

In fact he states (talking about the good shortstack player's range) "As you can see you're going to be getting it in behind the short stack's range quite a bit." Which is essentially the same as saying "ITS ONLY 20BB GAMBOOOOL!" Clearly any time you're putting money in the pot with the worst hand hand against a shortstack's better hand, he's going to win more often than you are. And therefore he's going to take your money. I dont even understand how anyone can suggest that you should 3bet a shortstack lightly.
