Tournaments

Tournaments are an exciting and profitable way to play poker.  Most of you have probably seen poker tournaments on television.  Tournaments are a fun thing to do at your weekly poker night.  For beginners, tournaments are nice because they have a built in "loss limit" - you pay the fee to enter and you can't lose any more than that.

Playing a short stack well in a tournament is crucial.  You will frequently get onto a short stack for various reasons, and if you don't play it well, you will be a losing tournament player over all.  Many people just give up when they get on a short stack, or they think they desperately need to double up and start shoving their chips in the pot with anything.  That's bad play.

When you are on a short stack, you can still intimidate people.  The thng is, people know that once you get committed to a hand, you are likely to get all-in.  That puts a lot of pressure on them, becuase they know that they may have to play for all the chips in your stack.  You can use this to put good pressure on them just by making small raises preflop.  You know that you're smarter than what they think.  You won't get your chips all-in when you're dominated.  You will put your chips in when you're getting good pot odds, but not when you're dominated.  When you know you're probably way behind, you should lay down the hand.

There are some hands that play better with a short stack.  Hands like A7, you can push all-in with.  You'll get called from better aces (very bad), but also worse aces and hands like KQ, KJ, and pocket pairs.  If you don't get all-in, A2 is very hard to play.  Against the blinds, you can play even stranger hands like K9, because even if you're behind you're getting good odds.  People know you're despearate on a short stack so they call with junk.  Your advantage comes in that you know which hands play well all-in.  You know that A2 is much better than TJs.  Most people don't properly adjust for this - they keep playing the hands that want to see flops.
