What are the advantages to assessing player stack size in number of big blinds remaining?
A) Psychological Factors
To make clear decisions, you need to understand poker in terms of big blinds rather than money. Distancing yourself emotionally allows you to make the best decision.
B) Understanding the effective stack
Understanding our own stack and our opponent’s stacks in terms of how many big blinds gives us the “effective stack” of any situation. If we raise pre-flop with a 200bb stack and are called by a single player in the big blind who has a stack of 100bb, then we can only win or lose up to 100bb. Therefore, the effective stack is 100bb. If the player in the big blind had 20bb, then the effective stack would be 20bb.
What is the Unopened Preflop Raise poker statistic?
Unopened Preflop Raise (UOPFR) tracks the percentage of times that a player raises preflop when the action folds to him. This allows you to understand a player’s tendencies at a deeper level than the VPIP/PFR poker statistic. VPIP/PFR gives you a general idea of the player type of your opponent. UOPFR gives detailed information on the range of hands your opponent is playing from each position.
