The rule, exactly
Hold'em gives each player two private cards and everyone five shared ones, and the showdown hand is any five of those seven. There is no requirement to use one hole card, or two, or any. This is the rule that separates hold'em from Omaha, where exactly two hole cards and exactly three board cards must be used. It is why "do I have to have two cards in my hand" gets asked at all: the answer is different in the two games most often dealt side by side.
The consequence at showdown is simple. If the five community cards are the best hand available to you, so they are to everyone else still in, and the pot is split unless a player's hole cards make something better. A pair of kings in your hand does nothing when the board is a ten-high straight; an ace does nothing when the board is a flush unless it is the right suit and higher than the board's top card.
How often the board is a hand by itself
The five community cards are a random five-card draw from 52, so the frequency of each board type is the classic five-card poker table, enumerated here over all 2,598,960 boards rather than quoted.
| Board | Boards | Share | One in |
|---|---|---|---|
| Straight flush | 40 | 0.0015% | 64,974 |
| Four of a kind | 624 | 0.0240% | 4,165 |
| Full house | 3,744 | 0.1441% | 694 |
| Flush | 5,108 | 0.1965% | 509 |
| Straight | 10,200 | 0.3925% | 255 |
| Three of a kind | 54,912 | 2.11% | 47 |
| Two pair | 123,552 | 4.75% | 21 |
| One pair | 1,098,240 | 42.26% | 2 |
| High card | 1,302,540 | 50.12% | 2 |
Two lines matter for play. Just under half of all boards are five unpaired cards, on which no full house or quads is possible for anyone. And a board that plays itself as a straight or better arrives on 0.76% of deals: rare enough to be memorable, common enough that a regular player sees one most sessions.
What "counterfeited" means
The board can also take a hand away. Hold a small pair on a board that pairs twice higher, and your pair no longer plays: the best five cards are the board's two pair plus the highest kicker anyone holds. Hold 6-5 on a 7-8-9-T-J board and everyone has the same straight. Your hole cards were counterfeited, which is the ordinary word for the board making your hand irrelevant, and it happens most on the 49.29% of boards that carry a pair.
The practical reading: a hole card is worth exactly the improvement it makes over the five cards everyone can see, and on a board that has made a hand already that is often nothing.
Frequently Asked Questions
- Do you have to use your hole cards in Texas hold'em?
- No. Your hand is the best five cards from the two you hold and the five on the board, in any combination: both hole cards, one, or neither. Using neither is called playing the board.
- What happens if the best hand is the board?
- Every player still in the hand holds at least that hand, and the pot is split among them unless someone's hole cards improve on it. A hole card only matters if it makes a better five-card hand than the board alone.
- How often does the board make a hand on its own?
- The five community cards are a straight, flush, full house, four of a kind or straight flush 0.76% of the time, about one board in 132. They contain a pair or better 49.29% of the time and are five unpaired cards 50.12% of the time.
- Is it the same in Omaha?
- No. Omaha requires exactly two hole cards and exactly three from the board, so playing the board is impossible there. The any-five rule is specific to hold'em.
