Utilities of knowing average
Average is relevant information to know when playing tournaments. This information will tell us what style to adopt at a given time. Average is calculated simply by adding up all the remaining chips in play and dividing them by the number of players remaining in the tournament. This information should be related to the size of the blinds . For example, we are in a tournament and the bubble is approaching. You have 8 cash game (8000) and the blinds are 500/1000. You receive a marginal hand to go all in préflop, but still profitable. You are not sure of your decision. Taking a look at the average may give you some relevant information. If the average is 20,000 chips, then 20 cash game, you should play more aggressively than if the average is 8,000 chips.
