Poker hands
Every poker variant ranks hands using the same ten-category hierarchy, determined by the mathematical rarity of each five-card combination. A royal flush—ace through ten of the same suit—stands alone at the top because only four such hands exist in a standard deck. At the opposite end, high card applies when no other combination forms, making it the most common outcome. Between these extremes, the ordering reflects a simple principle: the harder a hand is to make, the more it beats.
Poker Hand Rankings Explained
The standard ranking system governs all major poker games, from cash tables to tournament play. Each hand belongs to exactly one category, and ties within a category are broken by comparing the highest relevant card ranks. Understanding this structure is essential because showdown value depends entirely on where your combination sits in the hierarchy.
| Hand ranking | Card formation required | What it beats | Probability (five-card deal) |
|---|---|---|---|
| Royal flush | Ace, king, queen, jack, ten of the same suit | Every other hand | 0.000154% |
| Straight flush | Five consecutive ranks of the same suit (excluding royal flush) | Four of a kind and below | 0.00139% |
| Four of a kind | Four cards of the same rank plus any fifth card | Full house and below | 0.0240% |
| Full house | Three cards of one rank plus two cards of another rank | Flush and below | 0.144% |
| Flush | Five cards of the same suit in non-consecutive ranks | Straight and below | 0.197% |
| Straight | Five consecutive ranks of mixed suits | Three of a kind and below | 0.392% |
| Three of a kind | Three cards of the same rank plus two unmatched cards | Two pair and below | 2.11% |
| Two pair | Two cards of one rank, two cards of a second rank, plus one unmatched card | One pair and below | 4.75% |
| One pair | Two cards of the same rank plus three unmatched cards | High card only | 42.3% |
| High card | Five unmatched cards that form no other combination | Nothing—loses to any pair or better | 50.1% |
The probability column shows why this ordering exists. Out of 2,598,960 possible five-card combinations, only four are royal flushes. High card and one pair together account for more than ninety percent of all hands, which is why aggressive betting with marginal holdings often wins pots without reaching showdown. The gap between adjacent categories varies considerably: the jump from flush to full house represents a meaningful shift in scarcity, while the distance between one pair and high card is comparatively narrow.
When two players hold hands in the same category, the highest relevant rank wins. Two pairs compare the higher pair first, then the lower pair, then the fifth card. A straight or flush compares only the top card. Four of a kind and full house each have a primary rank that dominates the comparison. Suits never break ties in standard poker; if two players hold identical hand values, the pot is split.
Why Sequential and Suited Patterns Create Higher Ranks
Rank matching—pairs, trips, quads—depends only on pulling specific values from the deck, which happens with predictable frequency as you add cards. Straights and flushes impose additional constraints: consecutive ordering or identical suits. Those extra conditions shrink the number of qualifying combinations, pushing suited and sequential hands above three of a kind despite using fewer matching ranks. A flush requires all five cards to share one of four suits, while a straight demands an exact five-card sequence. Both are harder to assemble than three matching ranks plus two random cards, so both beat three of a kind.
The full house sits above the flush because it combines two rank-matching patterns—three of a kind and a pair—in a single hand. Although rank matching is individually easier than suiting five cards, requiring both patterns simultaneously is rarer than achieving either one alone. Straight flush demands both consecutive ranks and a shared suit, making it the second-rarest hand. Royal flush is simply the highest possible straight flush, capped at ace through ten to distinguish it as the absolute peak.
How Hands Form Across Poker Variants
Different poker games deal different numbers of cards and use distinct structures—community boards, private hole cards, or combinations of both—but every variant applies the same ten-category ranking when comparing final hands. The path to building a flush or straight changes; the value of that flush or straight does not.
Texas Hold'em and Omaha: Community Card Games
Texas Hold'em deals two private hole cards to each player and five community cards shared by the table. You build your best five-card hand using any combination of your two hole cards and the five board cards. You might use both hole cards, one, or none. The flexibility means that strong hole cards can be overtaken when the board pairs or completes a straight, and weak starting hands occasionally catch perfect community cards to make the nuts.
Omaha deals four hole cards instead of two, but imposes a strict formation rule: your final five-card hand must use exactly two of your hole cards and exactly three from the board. This constraint fundamentally changes hand construction. In Hold'em, ace-king of spades in your hand combines with three more spades on the board to make a flush. In Omaha, you need at least two spades in your four-card hand to complete a flush with three board spades; holding one spade or four spades both fail the two-from-hand requirement. The rule limits the combinations available from a larger starting set, which paradoxically makes some draws easier to miss despite having more initial cards.
Because Omaha players start with four hole cards and must use two, hand equities run closer together preflop than in Hold'em. Strong Omaha hands typically have multiple ways to connect with the board—pairs that can boat up, suited cards that can make flushes, connected ranks that can form straights—and hands that rely on a single high pair without backup often lose value. The same ranking system applies, but the likelihood of multiple players making strong hands by the river rises sharply.
Seven-Card Stud and Five-Card Draw: No Community Cards
Seven-Card Stud deals no shared board. Each player receives seven individual cards—three down, four up—and builds the best five-card combination from that private set. The absence of community cards means each hand develops independently. You see four of your opponents' seven cards during the hand, which provides partial information about likely holdings and remaining outs. Calculating your chances requires tracking exposed cards across all active players, not just reading one shared board.
Five-Card Draw gives each player exactly five private cards, with one opportunity to discard and replace cards after the initial deal. You construct your final hand from the five cards you hold at showdown. The game offers less information than Stud because no cards are exposed during play, and hand strength inference depends entirely on betting patterns and the number of cards each opponent draws. A player who stands pat (draws zero cards) likely holds a made straight, flush, or full house, while someone drawing three cards probably started with a pair.
In both games, the total number of available cards shapes the probability of improvement. Seven cards give you twenty-one different five-card subsets to evaluate, which means strong hands form more often in Stud than in Draw. The ranking hierarchy remains identical—quads beat a boat, a boat beats a flush—but the frequency at which each hand appears shifts with the deal structure. A flush in Draw carries more weight relative to the field than the same flush in Stud, because fewer total cards were available to construct it.
Evaluating Hand Strength in Context
Absolute rank tells you which hand wins at showdown, but practical strength depends on factors that change during the hand. Board texture, position, opponent tendencies, and stack depth all influence whether a particular holding should continue or fold. A set (three of a kind made with a pocket pair) ranks well below a straight in the hierarchy, but on a rainbow, unpaired board, the set is often ahead while the straight may not yet exist.
Board Texture and Range Advantage
Certain boards favour the betting range of one player over another, independent of hand rankings. A flop showing king-seven-two in three different suits connects weakly with most hands, giving high pairs and top-pair holdings significant equity. The same flop in all spades changes the dynamic completely: flush draws become immediate threats, and even a pair of kings faces meaningful vulnerability. A board of ten-nine-eight with two hearts offers straight and flush possibilities that can trap overpairs, while a paired board like queen-queen-four suppresses action because the pair of queens blocks strong holdings.
Range advantage often matters more than any single hand's rank. If the board shows ace-king-queen and you opened from early position, your range contains more strong aces, kings, and big pairs than a defender's calling range. Even modest hands like ace-jack gain value because they comfortably beat many weaker pairs and unimproved hands your opponent likely holds. Conversely, a low, connected board like seven-six-four favours the caller's range, which includes more suited connectors and small pairs that the early-position opener would have folded preflop.
Position and Information Asymmetry
Acting last provides information advantage. If you hold a modest hand like second pair and your opponent checks, you gain a data point suggesting weakness or a draw. That check may allow you to see another card cheaply or value-bet a thin holding that would be difficult to continue against aggression. The same second pair in early position must act first, committing chips before observing how opponents respond. Strong hands benefit from late position because you can raise for value after opponents show interest, and weak hands benefit because you can fold without investing more when facing bets.
Position amplifies edge over multiple streets. Even a strong hand like top pair loses value in early position when deep stacks remain, because you face difficult decisions on the turn and river without knowing whether opponents will raise or call. A set, which ranks lower than a straight or flush, becomes more playable from any position because its high equity and disguised strength let you call bets comfortably and build pots regardless of action sequence.
When Strong Ranks Become Vulnerable
A straight or flush has clear showdown value, but both can be beaten by better versions of the same hand type. The nut flush—ace-high flush—is effectively unbeatable within the flush category, but any lower flush faces the risk that an opponent holds a higher one. Straights create similar problems: holding queen-jack for a straight on a ten-nine-eight board loses to anyone with king-queen or jack-seven. On boards that heavily coordinate suits or ranks, strong-but-non-nut hands often have to fold to persistent aggression, even though they beat ninety percent of possible holdings.
Full houses and four of a kind largely avoid this vulnerability. Once the board pairs, a full house is difficult to beat unless the opponent holds a bigger boat or quads. Straights and flushes become drawing hands or second-best traps when the board pairs on the turn or river. A player holding the nut flush on a nine-seven-four-two board might confidently put in chips, only to see a four arrive on the river, making any pocket pair into a full house and leaving the flush behind.
- Consider how many better hands the board allows, not only the absolute rank you hold.
- Adjust your assessment when turn or river cards introduce new straight or flush possibilities.
- Recognise that opponent aggression often correlates with the top of their range, especially on coordinated boards.
- Treat non-nut versions of straights and flushes as strong but not invincible, and be willing to fold when action escalates.
Playing Poker in New Zealand
New Zealand residents can play poker at land-based casinos operating under the Casino Control Act 1990. These venues offer cash games, tournaments, and private poker rooms with regulated oversight by the Department of Internal Affairs. Approved casinos meet licensing standards covering game fairness, dispute resolution, and responsible gambling measures.
The Online Casino Gambling Act 2026, which took effect on 1 May 2026, introduced a licensing framework for online casino gambling including poker. The Department of Internal Affairs now administers this regime, allowing licensed operators to offer remote interactive gambling to people physically located in New Zealand. The Act defines online casino gambling as remote interactive gambling of a kind ordinarily available at a casino, which explicitly includes poker. Any entity offering online poker to New Zealand residents must hold a licence issued by the DIA or face enforcement action, including takedown orders and pecuniary penalties up to five million dollars.
Offshore operators that provided services to New Zealand customers before 1 May 2026 were allowed to continue operating until 1 December 2026 while the licensing process commenced. After that date, only operators holding a DIA licence may legally offer online poker to New Zealand residents. The Act prohibits advertising online casino gambling services without a licence, and operators not meeting the new requirements are expected to exit the market or face enforcement.
The 2026 Act targets supply-side compliance, not individual players. It introduces local rules governing which operators can lawfully offer online poker, but it does not criminalise participation by New Zealand residents. Players accessing offshore sites that lack a DIA licence are using services outside the new regulated framework, which means they do not benefit from the consumer protections, dispute resolution processes, or responsible gambling mechanisms that licensed operators must provide. The distinction matters: a licence confirms that an operator meets New Zealand standards; the absence of a licence means no such confirmation exists.
What does a straight beat in poker?
A straight beats three of a kind, two pair, one pair, and high card. It loses to a flush, full house, four of a kind, straight flush, and royal flush.
Can you make a flush with one suited card in Omaha?
No. Omaha requires you to use exactly two cards from your hand and exactly three from the board. You need at least two suited cards in your four-card hand to complete a flush with three board cards of the same suit.
How often does a pair win in Texas Hold'em?
One pair forms in roughly 42 percent of random five-card deals, making it the second most common hand after high card. Many pots in Hold'em are won by a pair or less because players fold before showdown.
Does a full house always beat a flush?
Yes. A full house ranks above a flush in the standard poker hierarchy regardless of the specific cards involved. Even the lowest full house—twos full of threes—defeats the highest possible flush.
Are offshore poker sites legal in New Zealand?
Offshore sites without a licence issued by the Department of Internal Affairs cannot lawfully offer online poker to New Zealand residents under the Online Casino Gambling Act 2026. The Act does not penalise players, but unlicensed operators do not provide the consumer protections required by New Zealand's licensing framework.
