The ranking table decides the winner when two hands sit in different categories. But most showdowns end with both players in the same category — that is where tie-breakers take over.
When the kicker matters. A kicker is the highest card in your hand that is not part of the combination itself. If you both hold a pair of aces, the higher side card wins. A♠-K♦ against A♥-Q♣ on A-7-4-2-9: both have aces, your king beats the queen. Kickers only apply while your best five cards are not yet complete — so a straight, flush or full house never uses one.
Same pair. With identical pairs you compare kickers one at a time: highest, then second, then third. If all three match, the pot is split.
Same two pair. Compare the top pair first, then the bottom pair, and only then the fifth-card kicker. Aces and deuces beat kings and queens — the higher pair decides first.
Same straight or same flush. A straight is judged only by its highest card; two straights ending on the same card split the pot. A flush is compared card by card from the top: A-J-8-5-3 beats A-J-8-4-2. The suit itself never breaks a tie.
When the board plays. If the five community cards make a stronger hand than any combination using your hole cards — a board of 10-J-Q-K-A, for example — everyone plays the same hand and the pot is split between all remaining players. You always pick the best five cards out of seven, even when none of them are the two you were dealt.
One rule to remember: a poker hand is always exactly five cards. There is no sixth kicker, and it is never counted.
