Effective remaining stack divided by the pot at the start of a street.
Common abbreviation: SPR
Sign in to save this term ↗What it means
Low SPR makes large portions of a stack easier to commit; it does not dictate an automatic action.
A practical example
A 100 pot with 400 effective behind has an SPR of 4.
The calculation
SPR = smaller remaining stack ÷ current pot at the start of a street.
The example above shows the idea with stated assumptions. Actual decisions also depend on ranges, future action, and the game format.
Where you will hear it
Texas Hold’em, Omaha where applicable. The exact usage can vary with rules and context.
