Tournament Game Structure

A tournament game differs from a normal or 'cash' poker game because the blinds increase throughout the game.  The blinds are a forced bet that the two players to the left of the dealer have to place before any cards are dealt.  Usually in tournaments the blinds will double after a fixed period of play, until eventually the blind size might even exceed the chips each player started with.  The period and amount the binds increase is called the 'structure'.  

The game structure determines fairly precisely how long the game will go for and also how much action (how frequently players bet) there is in the game.

Since it is likely there will be many people who have either never played or are very new to Texas Hold'em, this game structure has been designed to give new players plenty of time to get used to the game.

It may vary slightly on the day, but this is close to how the game will be structured with starting chips of 5,000:

Level Duration Blinds (Small/Big)
1 30 mins 25/50
2 30 mins 50/100
break

3 20 mins 75/150
4 20 mins 100/200
5 20 mins 150/300
break

6 15 mins 200/400
7 15 mins 500/1000
8 15 mins 1000/2000
9 15 mins 2000/4000
break

10 15 mins 4000/8000
11 15 mins 8000/16000

With eight people starting the game, there is 40,000 chip value in play.  You can see that if the games goes to level 11, then on each hand, just about all the chips are used for the blinds on every hand.  It is impossible for the game to go longer than about three and a half hours with this structure, and most likely it will end around level eight or nine.

Relatively long early levels and a large starting chip stack means players can get a feel of the game and play conservatively without much pressure.  Most players should still be in the game at level 6.

Level 7 however is the point where the game accelerates.  The blinds become very large in relation to stack sizes, and no one can afford to sit around and wait for premium hands.  At this stage the game becomes very exciting for players and spectators alike.  Large bets or all-ins are made on often marginal hands, and the fate of players is decided on the fall of the cards.  Chip leads can change in one or two hands as a 'lucky river' card can turn the table underdog into the dominating chip leader.

For those who unluckily are already out for the game, the accelerating structure means the game remains interesting to watch as you barrack for a remaining favorite to win.  But also, there is not too much time to wait until the game reaches an ultimate conclusion.
