Texas Hold'em is a highly strategic and psychological poker game, here are its core gameplay and rules:

1. Game Objective

Combine two hole cards and five community cards to make the best five-card hand and win chips in the pot. Players can maximize profits through betting, bluffing, or folding.

2. Basic Rules

1. Number of Participants

Usually 2-10 players, commonly 6-9 player tables online.

2. Hand Strength

- From highest to lowest: Royal Flush > Straight Flush > Four of a Kind > Full House > Flush > Straight > Three of a Kind > Two Pair > One Pair > High Card.

3. Betting Order

Proceed clockwise, starting position determined by the Dealer Button.

3. Game Process

1. Dealing and Blinds

- Small Blind (SB) and Big Blind (BB): Forced bets that initiate the pot.

- Each player is dealt two hole cards, visible only to themselves.

2. First Round of Betting (Pre-flop)

- Start from the player to the left of the big blind, choose: call, raise, or fold.

3. Flop

- Three community cards are dealt, shared by all players.

- Second round of betting: Starts with the player to the left of the dealer, who can choose to check or bet.

4. Turn

- The fourth community card is dealt.

- Third round of betting: The rules are the same as the second round, with betting amounts usually doubled.

5. River

- The fifth community card is dealt.

- Fourth round of betting: Last opportunity to raise.

6. Showdown

- If 2 or more players remain, reveal hole cards; the player with the best five-card combination wins.

4. Key Strategies and Techniques

1. Starting Hand Selection

- With strong hands (like AA, KK, AK), raise aggressively; with weak hands (like 72o), fold early.

- Players in late positions (like the dealer position) can widen their hand ranges.

2. Reading Hands and Range Analysis

- Estimate potential hand ranges based on opponents' actions.

- Observe betting patterns (aggressive/conservative) to judge bluffing tendencies.

3. Probability Calculation

- Calculate outs after the flop to improve the odds of making your hand.

- For example: Flopping a flush draw with 9 outs remaining, approximately 36% chance.

4. Bluffing and Value Betting

- Bluffing is more successful on dry boards (no straight or flush possibilities).

- Make small bets with strong hands to induce calls and maximize profits.

5. Common Variants

- No-Limit Texas Hold'em: Any bet amount, allows all-in, mainstream competitive play.

- Tournament (MTT): Fixed buy-in, elimination format, chip count affects strategy.

- Cash Game: Buy in anytime, chips equivalent to real money.

6. Important Considerations

- Bankroll Management: Avoid investing more than 5% of your total bankroll in a single hand.

- Emotional Control: Avoid 'tilt' leading to irrational decisions.

- Observe opponents: Note habits (like frequent bluffs or tight-passive styles).
