WSOP Deep Stack Mistake #5: Playing Too Straightforwardly
With shallow stacks, you will quickly run into a mathematical limit on the number of hands that you can profitably play from a given position, at least when there are other competent players at the table. When stacks are deep, the greater danger is in playing too few hands. If other players can put you on a very narrow range based on your pre-flop action, then you will have a difficult time turning a profit.
This means that you must occasionally raise with small suited connectors in early position or re-raise with a hand other than AK or a big pair. Even if only 10% of your re-raises or early position raises are semi-bluffs, this drastically reduces the implied odds your opponents can count on when contemplating a call and makes it easier for you to get value when you do have a legitimate hand.
