Win in Beginning and Lose toward end

Hi All: I do pretty good in the beginning of a tournament and then I just cant win nothing and end up losing. What am I doing wrong?

The better players are left toward the end. Practice, practice, practice and read, read, read.

Also practice how to single post.

I will suggest that once you get an above average stack you need to play different. Stop taking unnecessary risks. This is not to say shut down entirely. In fact you can afford to be a bit more adventurous, seeing connectors or flush deals cheap. Key word is CHEAP! Be ready, NAY!, be more than willing to lay down those cards if you don't hit the flops.
Do not get married to pretty cards.
Do not chase improbable dreams.
Avoid confrontations.
Learn and employ position and positional plays.
Then read all of these;

I had the same problem with doing great in the beginning and then it all goes down hill.. I have been practicing alot more lately and it seems like im slowly moving towards the final tables now.

Without more information it is hard to be specific. However, the main difference is that you play with smaller stacks(or short stacks) in the later stages of a tournament.

For short stacks(<10BB), you don't limp or raise 2-3BB. You look for a hand to go all-in. Ideally, you will open-raise so there is the least resistance possible. You would be happy just to get the blinds.

For small stacks (say 10-20BB), play high cards and pairs in position. Don't draw since you don't have the odds to draw to str8s, flushes or sets. Occasionally steal some blinds since you will not get enough good hands to keep you alive.

With stacks >20BB you should steal more, but don't be a maniac. You can now add SC and small pairs as drawing hands if you are against a stack at least 10 times your pre-flop call/bet. But with SCs you should be in position.

And finally, don't look how you compare to the average. Just compare where you stand with respect to the blinds and the players on your table. There is nothing you can do about the average chip stack. Don't try to "catch-up". If you force the action, you will likely get in a bad situation. At this stage all it takes is one error and you are crippled or out.

Read Harrington's books, play more tourneys and you will definitly improve.

i had a similar problem a while ago i always finished last 30 or so and never made final table, i then started playing more agressive at this stage and steal blinds n things n then i made it to the final table when i played like that but be patient before that u dont need to go allin on a 50 50 chance of winning just wait till u get nuts or close to
