Question

I have recently heard the term SPR applied to cash games. What does it mean?

Answer 1

Stack-to-pot ratio (SPR) is a metric first published by Matt Flynn, Sunny Mehta, and Ed Miller in Professional No-limit Hold 'em: Volume One.

It is calculated by dividing the effective stack against a given opponent by the size of the flop pot. (SPR always refers to the size of the pot and stacks at the flop, i.e. between preflop and flop betting.)
