Frequently Asked Questions (FAQ)
What is equity in poker?
Equity represents your mathematical share of the pot based on your probability of winning at showdown if all remaining community cards are dealt to completion.
What is the math behind a classic "Coin Flip"?
A pocket pair versus two overcards (e.g. Q♠ Q♥ vs A♦ K♣) is poker's quintessential coin flip, dividing equity roughly 54% to 46% in favor of the pocket pair against offsuit overcards, or 57% to 43% against suited Broadway.
How heavily favored is an Overpair against an Underpair?
An overpair versus an underpair (such as A♠ A♥ vs K♦ K♣) is a commanding 81% to 82% favorite. The underpair requires hitting one of its two remaining sets (~18%) to crack the aces.
What does "Domination" mean in poker matchups?
Domination occurs when two players share a common card rank, but one holds a higher kicker (e.g., A♠ K♥ vs A♦ Q♣). The dominating hand commands roughly 72-74% equity because the dominated player only has 3 outs to pull ahead.
How does the flop texture reshape hand equity?
The three flop cards reveal over 70% of the hand's final information. A starting pocket pair can drop from an 80% preflop favorite to under 25% on a wet coordinated flop connecting heavily with opponent holdings.
