Quick Answer
Understanding poker equity
Poker equity is your probability of winning the pot. AA vs KK preflop is ~82% vs 18%. AKs vs QQ is a classic coin flip at 46% vs 54%. On a favorable flop, equities shift dramatically - AK hitting top pair vs QQ becomes ~91% vs 9%.
Key Facts About Poker Equity
Essential concepts to know
- ✓AA is only ~82% vs any single random hand preflop, not invincible
- ✓AK suited vs a small pair (like 22) is roughly 48% vs 52% - a slight underdog
- ✓Suited hands add about 3-4% equity compared to their offsuit counterparts
- ✓Position doesn't affect equity directly, but it helps you realize that equity
- ✓Multiway pots drastically reduce individual hand equities
- ✓Equity realization is how much of your mathematical equity you actually capture
- ✓Blockers matter - holding an Ace reduces opponents' chances of having AA/AK
Frequently Asked Questions
Common questions about equity
How is poker equity calculated?
Equity is calculated by running through all possible board runouts and counting how often each hand wins. For preflop scenarios, there are over 1.7 million possible board combinations. Modern calculators use Monte Carlo simulation to estimate equity by sampling thousands of random runouts.
What is the equity of AK vs small pairs?
AK (aka Big Slick) is roughly a coin flip against small to medium pairs. AKs vs 22-TT is approximately 46-48% equity. AKo is slightly worse at 43-45%. The pair is a small favorite because AK needs to hit to win, while the pair is already made.
How does the board change equity?
The board dramatically shifts equity. If you hold AK and the flop comes A-7-2 rainbow against QQ, you go from ~43% preflop to ~91% equity. Conversely, if the flop comes Q-7-2, your equity drops to about 9%. This is why hand reading and position are crucial.
What is equity realization?
Equity realization is the percentage of your mathematical equity you actually capture in practice. Position, skill edge, and stack depth affect this. In position with a skill edge, you might realize 100%+ of your equity. Out of position against a strong player, you might only realize 70-80%.
Suited vs offsuit - how much difference?
Suited hands have about 3-4% more equity than offsuit equivalents. AKs vs AKo is about 67% vs 63% against a random hand. The flush potential and backdoor draws add up over all possible boards. This is why suited aces and suited connectors are more playable.
How do I use equity in decisions?
Compare your equity to pot odds. If you have 35% equity and pot odds require 25%, calling is profitable. Preflop, use equity to determine calling ranges. Postflop, use it to size bets, make calls, and determine when to fold or continue.
How this works
Calculations follow the published mathematics of the game — combinatorics for cards, probability theory for dice, and expected-value accounting for wagers. Results are verified against independent references (primarily Wizard of Odds). No calculation here is an opinion or recommendation; it is arithmetic applied to the rules of the game.
