Showdown Rules

Beginner

Definition

A showdown occurs when two or more players remain after all betting is complete. Players reveal their hands to determine who wins the pot.

When Does Showdown Happen?

Showdown occurs when:

  1. All betting rounds complete (river betting ends)
  2. At least 2 players remain
  3. All players are either all-in or have matched bets

No showdown needed if everyone folds to one player—they win automatically.

Order of Showing

Standard Rule (Casino)

Situation Who Shows First
River bet/raise was made Last aggressor shows first
River was checked down First active player left of button

In Practice

  • Last aggressor must show first
  • Other players can muck (fold without showing) if beaten
  • Winner must show to claim pot

Showing Options

Option When to Use
Show Required if you want to win
Muck If you're beaten and don't want to reveal
Show one Some casinos allow, others require both

The "Show One, Show All" Rule

In most card rooms:

If you show your cards to one player, you must show everyone.

This prevents selective information sharing.

Showdown Etiquette

✅ Good Etiquette

  • Show promptly when it's your turn
  • Table your hand clearly (face up, visible)
  • Let dealer read the hand
  • Muck gracefully if beaten

❌ Poor Etiquette

  • Slow-rolling (delaying with a winning hand)
  • Fake mucking then showing a winner
  • Exposing your cards to railbirds
  • Arguing about hand rankings

Hand Comparison

At showdown, hands are compared:

  1. Best 5-card hand wins
  2. Both hole cards not required
  3. Kickers break ties
  4. If identical—split pot

Example

Board: K♠ K♥ 7♣ 4♦ 2♠

Player Hole Cards Best Hand Kicker
Player A A♠ Q♥ K♠ K♥ A♠ Q♥ 7♣ Ace
Player B A♦ J♠ K♠ K♥ A♦ J♠ 7♣ Ace, Jack

Player A wins — Higher kicker (Queen vs Jack)

All-In Showdown

When everyone is all-in:

  • All hands are typically shown
  • No strategic reason to hide
  • Cards often dealt face-up for remaining streets

Online vs Live

Aspect Online Live
Showing Auto-show at showdown Must physically table cards
Reading hands Software determines Dealer/players read
Mucking Click muck button Push cards to dealer

Key Takeaway

At showdown, the best hand wins. Last aggressor shows first. You can muck if beaten, but you must show to win. Good etiquette keeps the game friendly—never slow-roll.
