How to Play Texas Hold'em
Texas Hold'em is a game of skill, strategy, and a little bit of luck. The goal is simple: win the pot. The pot is the collection of chips bet by all players in a hand. You can win in two ways:
- Have the best five-card poker hand at the end of all betting rounds.
- Be the last player remaining after everyone else has folded.
Each player is dealt two private cards, called hole cards. Five community cards are then dealt face-up in the middle of the table for everyone to use. Your job is to combine your two hole cards with the five community cards to make the best possible five-card hand.
Hand Rankings
Knowing which hand beats which is the most important part of poker. The hands are ranked from highest to lowest. If two players have the same type of hand (like two flushes), the hand with the higher-ranked cards wins.
Here are the standard poker hand rankings, from the unbeatable Royal Flush down to a simple High Card.
| Hand | Description |
|---|---|
| Royal Flush | A, K, Q, J, 10, all of the same suit. |
| Straight Flush | Five cards in sequence, all of the same suit (e.g., 9, 8, 7, 6, 5 of hearts). |
| Four of a Kind | Four cards of the same rank (e.g., four Aces). |
| Full House | Three cards of one rank and two cards of another rank (e.g., three Kings and two 7s). |
| Flush | Any five cards of the same suit, not in sequence. |
| Straight | Five cards in sequence, but not of the same suit. |
| Three of a Kind | Three cards of the same rank. |
| Two Pair | Two cards of one rank, two cards of another rank, and one other card. |
| One Pair | Two cards of the same rank. |
| High Card | If no one has any of the above, the player with the highest card wins. |
The Flow of a Hand
A hand of Texas Hold'em follows a set structure of dealing cards and betting rounds. It all starts with the blinds and the dealer button.
Before any cards are dealt, two players must post 'blinds', which are forced bets that start the pot. The player to the immediate left of the dealer button posts the small blind, and the next player to the left posts the big blind (usually double the small blind).
Then, the hand proceeds through up to four betting rounds:
In each betting round, players have several options. The action proceeds clockwise around the table, starting with the player to the left of the big blind (pre-flop) or the player to the left of the dealer button (on all later rounds).
| Action | Description |
|---|---|
| Check | Pass the action to the next player without betting. You can only check if no one has bet before you in the current round. |
| Bet | Make the first wager in a betting round. |
| Fold | Discard your hand and forfeit any chance of winning the pot. |
| Call | Match the amount of the current bet to stay in the hand. |
| Raise | Increase the amount of the current bet, forcing other players to call the new, higher amount. |
A betting round ends when all players who haven't folded have put the same amount of chips into the pot. If a player bets or raises and no one calls, that player wins the pot immediately without having to show their cards.
