All-In Rules & Side Pots Explained

Poker Guides · Rules

Side pots confuse a lot of newer players the first time they encounter one - multiple players all-in for different amounts, with chips seemingly split into separate piles. The underlying logic is actually simple once you see the mechanics laid out clearly.

The Basic Rule: You Can Only Win What You Contributed To

The core principle behind every side pot: a player can never win more from any single opponent than the amount they were able to match. If you go all-in for $50 and your opponent has $200 in front of them, you're only eligible to win a pot built from up to $50 of your opponent's chips - you have no claim on anything beyond that, since you never had enough chips to call it.

How a Main Pot and Side Pot Form

Say three players are in a hand: Player A goes all-in for $50, Player B calls with $50 (matching exactly), and Player C - with a much bigger stack - raises to $200, which Player B cannot fully match since they're already all-in at $50.

Here's what happens:

• A main pot forms containing $50 from each player (the amount everyone could match) - all three players are eligible to win this pot.
• A side pot forms from the additional $150 that Player C bet beyond what Player A could match - only Player C (and any other player who called that additional amount) is eligible to win this side pot, since Player A never contributed to it.

If more players go all-in at different stack sizes within the same hand, the dealer creates additional side pots as needed - each one specific to the players who were still able to contribute chips beyond the previous all-in threshold.

Showdown With Multiple Pots

At showdown, each pot is awarded independently based on the best hand among the players actually eligible for that specific pot. It's entirely possible for a player to win the main pot while losing the side pot to a different opponent, or vice versa - the pots are evaluated completely separately, even though they were built from the same hand.

Do All-In Players Still See the Rest of the Hand?

Yes. Once a player is all-in and has no further betting decisions remaining, the hand still runs to completion - all remaining community cards are dealt, exactly as they would be with normal betting - and the all-in player remains fully eligible to win whichever pot(s) they contributed to, based on their final hand at showdown. This is why "running it" all the way to the river regardless of remaining betting action is standard, not optional.

Why Understanding This Matters Practically

Beyond avoiding confusion at the table, understanding side pot mechanics affects real strategic decisions - particularly around when it's correct to go all-in with a short stack versus a deeper one, since a short all-in stack can only ever win the main pot, capping your potential upside even if the hand plays out well for you. This connects directly to tournament final table dynamics, where stack-size differences and their side-pot implications become especially important - see our Final Table Strategy guide for more.
