Mixed Games Introduction: HORSE Rules Overview

Definition and Origin

HORSE is a rotation-style mixed poker game. Its name is an acronym formed by the first letters of five poker variants: Hold'em, Omaha Hi-Lo, Razz, Seven Card Stud, and Eight or Better (Seven Card Stud Hi-Lo). In professional tournaments and cash games, HORSE is considered a true test of a "complete player," requiring mastery of different rules, betting structures, and hand-reading skills.

Core Rules of the Five Variants

1. Hold'em (Texas Hold'em)

• Each player is dealt 2 hole cards, and 5 community cards are revealed in three stages (flop, turn, river).
• Goal: Use 2 hole cards and 3 community cards to form the best five-card hand.
• Note: In HORSE, Hold'em is typically played in Limit form, meaning fixed bet sizes per round.

2. Omaha Hi-Lo

• Each player is dealt 4 hole cards, and 5 community cards are revealed.
• Players must use exactly 2 hole cards and 3 community cards to make the best high hand; simultaneously, they may use the other 2 hole cards (or the same two) with the community cards to make a low hand (if qualified: five different ranks all ≤8).
• The pot is split between the high hand and the low hand (if no low qualifies, the entire pot goes to high). A common mistake is players thinking they can use only 1 hole card.

3. Razz

• Similar to Seven Card Stud, but the goal is to make the lowest five-card hand (A is low; straights and flushes do not count).
• Each player first receives 3 cards (2 down + 1 up), then four more rounds where each player gets one up card (fifth street) and one final down card (seventh street).
• Unique rule: Betting starts with the player showing the lowest up card. If a player still has a qualifying hand by sixth street, they often raise to steal the pot.

4. Seven Card Stud

• Each player first receives 3 cards (2 down, 1 up), then four more rounds: one up card, one up card, one up card, and one down card.
• Goal: Select the best five-card hand from the seven cards (no community cards).
• Betting order each round starts with the player showing the highest up card (or the previous round's raiser). Unlike Hold'em, position in Stud is relative and depends on opponents' up cards.

5. Seven Card Stud Hi-Lo (Eight or Better)

• Basic rules are the same as Seven Card Stud, but the pot is split: best high hand and best low hand (low requires five different ranks all ≤8).
• Like Omaha Hi-Lo, multiple players can share the low, but only those holding small combos like A2 or A3 are usually competitive.

Practical Example (Educational)

Suppose a HORSE round rotates to Razz, with a blind structure of $1/$2 limit. Player A holds after fourth street: (x x) 2♥ 4♠ 6♦ (x represents down cards), currently showing the lowest up card of 2. Player B holds: (x x) 7♣ 8♥ K♠.

• Fifth street: Player A receives a 3♣ (down), Player B receives J♦ (up). At this point, A's up cards are 2♥ 4♠ 6♦ 3♣, a promising low draw; B's up cards are 7♣ 8♥ K♠ J♦, no low potential left.
• Action: According to rules, Player A, with the lowest up card, bets first for $1. A bets; B folds (since opponent is clearly drawing to a low, and B only has a pair of Kings with little chance to win).

This example illustrates that in Razz, you must continuously evaluate the trend of your own and your opponents' up cards; giving up too early or calling blindly are common mistakes.

Common Mistakes

1. Applying Hold'em thinking to all variants: For example, ignoring opponents' up cards in Seven Card Stud, or thinking you can use only 1 hole card in Omaha. Each variant has completely different hand value judgments and positional meanings.
2. Underestimating the impact of limit structure: HORSE is mostly limit; small fixed bets mean bluffing is cheap but value bets are also limited. You need to pay more attention to pot odds and hand ranges.
3. Rigid hand selection: E.g., preferring A2xx in Omaha Hi-Lo but neglecting other combinations, or thinking any three low cards are playable in Razz (you must consider opponents' up cards).
4. Ignoring the rotation rhythm: Switching from Stud to Hold'em, many players forget the difference in starting hands and lose chips in the Hold'em round by playing too many marginal hands.

Summary

HORSE is a test of comprehensive poker skills. Learning it not only broadens your game perspective but also deepens your understanding of position, hand reading, and range concepts. Beginners are advised to master the basics of each variant one by one before practicing rotation. Start with online limit tables or friendly home games to gradually adapt to the pace. The core of mixed games is not to become an expert in one game but to become a "poker generalist."
