Poker All-In and Side Pot Rules, with a Worked Example

An all-in wager is limited by the shortest stack

A player cannot win more from an opponent than that player put at risk against them. If Player A is all-in for 1,000 and Players B and C each continue for 3,000, only 1,000 from B and 1,000 from C can join A’s 1,000 in the main pot.

The unmatched layers belong in a side pot contested only by the players who contributed to that layer. Keeping the layers separate is the core idea behind every side-pot calculation.

Worked three-player side-pot example

Player A is all-in for 1,000. Player B is all-in for 3,000. Player C covers both players and calls 3,000. Ignore blinds already included in those totals for this simple example.

Award the 4,000 side pot using only B and C’s hands. Then award the 3,000 main pot using A, B and C’s hands. Player A can win the main pot but has no claim on the side pot.

When should all cards be turned face up?

If at least one player is all-in and every other player in the hand has completed all betting action, all live hands must be tabled immediately. Do not wait for the remaining community cards or for the pots to be awarded.

If two larger stacks still have chips and can bet later streets, their cards stay down because further action remains possible. Once their betting is also complete, table every live hand—including the short stack playing only for the main pot.

A reliable method for building the pots

First, leave all wagers in front of the players so the amounts remain visible. Identify the smallest total, multiply it by the number of contributing players, and move that layer to the main pot. Then repeat with the next-smallest unmatched amount to create the first side pot.

Do not mix side pots together before awarding them. Announce the amount and eligible players for each pot. If the table is confused, write the layers down or use distinct physical areas on the felt.

• Return any completely uncalled amount before building pots.
• Include folded players’ contributed chips, but folded hands are not eligible to win.
• Resolve the final side pot first, then work back to the main pot.
• Split tied pots separately and apply the published odd-chip rule.

Prevent the common side-pot errors

The most common mistake is sweeping every chip into one pile before confirming contributions. The second is allowing the all-in player to muck without showing after all action is complete. The third is comparing a short stack’s hand for a side pot they did not fund.
