Understanding the Stack-to-Pot Ratio (SPR) in poker is essential for making profitable decisions at the table. SPR refers to the ratio between the number of chips you have in your stack and the size of the pot. In simple terms, it indicates how much money is at stake in comparison to the number of chips you have.

Calculating SPR is easy. All you need to do is divide the size of your stack by the size of the pot. For example, if you have $500 and the pot has $50, your SPR would be 10:1.

Different SPRs have a significant impact on your decision-making at the table. Depending on the SPR, your hand strength can vary. Therefore, you should keep the Stack to Pot Ratio in mind when judging your hand strength.

In this blog post, we'll break down the three main buckets that relate to how you play certain hands based on the SPR.

SPR of 0-5:

When the SPR is low, such as 0-5, hands that can flop made hands such as top pairs and overpairs tend to do better than speculative hands that tend to have difficulty realizing their equity due to the lack of fold equity and lower implied odds. In such situations, you should aim to get as much money into the pot as possible when you have a strong hand. This is because there isn't much room for maneuvering once the flop is dealt, and you want to maximize your profits.

SPR of 6-11:

When the SPR is medium, such as 6-11, the value of top pair type hands becomes demoted, and the value of speculative hands increases. The equity realization of hands starts to revolve more around suitedness and connectedness than high card value. In this scenario, you should aim to see more flops and play hands that have the potential to make strong hands post-flop. It's important to note that playing too passively in this SPR range can be detrimental to your profits.

SPR of 12-20:

When the SPR is high, such as 12-20, more of a hand's value comes from its potential to make the nuts (nuttiness). Hands such as sets, nut draws, high flushes, and straights, that offer the possibility of coolering your opponent, increase in value. Single pair type hands will struggle to get to showdown in large pots unless they have some sort of backup equity. Therefore, you should aim to make strong hands or have the potential to make strong hands before committing too much money to the pot.

In conclusion, understanding the Stack to Pot Ratio is essential to making profitable decisions at the poker table. By considering the SPR, you can adjust your hand selection and decision making to maximize your profits. Remember to keep the SPR in mind during each hand and adjust your strategy accordingly.
