We’ve updated our “Unopened Preflop Raise” article
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.
We’ve revised almost every paragraph in this article. The examples are clearer, we’ve tried to use less poker slang, and to define it when we do use it.
