Stack size is almost an obsession in today's world. And we mean the stacks of chips that represent how much money one has to play poker with. There are those who say that size doesn't matter; of course these are the sort of people to whom the term "hung like a smurf" applies more than just their stack of chips. The ugly truth is that a big, healthy stack is more desirable to work with than a tiny one. This doesn't mean that one can't still be effective with a small stack. It just means you have to be more skilled with how you use it.
Let's say you are under the gun with a pair of Queens. This either means you are having a really interesting evening on Fisherman's Wharf, or you are the first one to act in the betting round before the flop. The pair of Queens and your short stack gives you a bit of an advantage.
If you bet, the big stacks around you will probably call in an effort to bully you out of the pot, thinking your short stack will make you easy to frighten. If they raise, call their raises.
This is an all or nothing play with your hand, so no matter what the flop is, you will go all in. The reason for this is that if you don't make a bold move at this point, the blinds will eat you up (if you are playing tournament poker), and chances are pretty good that the pair of Queens is the best starting hand at the table.
Your all in bet will give your opponents pause. The bigger stacks may feel insulated from the consequences of calling your bet and the medium stacks will be scared off, leaving their bets in the pot. This gives you the opportunity to double or triple your stack. Now that you are all in, the hand is on autopilot and your future is up to fate.
Chances are better than average that you will walk away the winner, and if you do, you will have dramatically increased your stack size.
Good Luck!
