Full explanation — Pre-Flop Raise
PFR (Pre-Flop Raise) is the percentage of hands in which a player opened the action with a raise before the flop. The gap between a player\u2019s VPIP and PFR reveals a lot about their style: a large gap means they frequently cold-call rather than raise, suggesting a more passive approach, while a small gap indicates an aggressive player who mostly enters pots by raising.
