Stack-to-Pot Ratio (SPR) Tutorial
What is Stack-to-Pot Ratio (SPR)?
SPR is the ratio of the effective stack size to the pot size at the start of a betting round. It helps determine how committed you should be to a hand.
Why is SPR Important?
- Helps determine when to commit with a hand.
- Guides post-flop decision-making based on stack depth.
- Prevents overcommitting with weak hands in deep-stacked situations.
How to Calculate SPR?
SPR is calculated using the following formula:
SPR = Effective Stack Size / Pot Size
SPR and Commitment Levels
Different SPR values indicate different commitment levels:
| SPR Range | Commitment Level | Example Hands |
|---|---|---|
| 0-2 | Very High Commitment | Top pair, overpairs, bottom two pair |
| 3-6 | Moderate Commitment | Top two pair, sets, strong draws |
| 7+ | Low Commitment | Nut hands, cautious play recommended |
