What is PFC in Poker? PFC stands for Preflop Caller, which is any player that calls a preflop raise. For example, let's say you're in the cutoff position in a $1/$2 No Limit Hold'em game, and the player in the LoJack raises to $10. If you decide to call the raise of $10, you are the preflop caller, or the PFC. View All Poker Terms. SPR stands for Stack-to-Pot Ratio, which is the ratio of the shortest stack in the hand (aka the effective stack) divided by the pot on any given street. For example, if the pot is $10 and the effective stack is $100, the SPR is 10 (100/10).
