How Side Pots Work in Poker: Who Can Win What

Every home game eventually arrives at the same frozen moment. Three players are all in, the board is out, the hands are face up, and there is a pile of mismatched chips in the middle that nobody quite knows how to divide. Someone says the short stack can't win all of it. Someone else says the best hand takes everything. The game stops while people re-count what everyone started with.

The rule that settles it is one sentence. You can only win, from each opponent, as much as you put in yourself. Everything a bigger stack bets beyond that goes into a separate pot, called a side pot, that only the bigger stacks can win. The rest of this article is that sentence turned into chips: how the pots get built, who wins what at showdown, and how to run it at a home table without the game stopping. If the table would rather watch than read, our sixty-second video covers exactly this moment:

Building the pots

Say three players see a hand through in a $1/$2 game. Player A started with $100, players B and C each have $600 behind.

A moves all in preflop for $100, and B and C both call. Each of the three has now put in $100, so the main pot is $300 (plus whatever the folded blinds left behind, which also belongs to the main pot). A can win this pot and nothing else, all night, no matter what happens next.

On the flop, B bets $200 and C calls. A is not asked for anything; a player who is all in cannot bet, call, or fold, and cannot be bet out of the pot they are already in. Those two $200 bets form a side pot of $400 that belongs only to B and C. Turn and river check through.

Two pots sit on the table: a $300 main pot that all three players are in, and a $400 side pot between B and C.

Who wins what at showdown

Side pots are awarded first, working backward toward the main pot. The dealer compares B and C, gives the $400 side pot to the better of those two hands, and only then compares all three players for the main pot.

Put cards on that example. A jammed with A♠A♦, B called with K♠K♣, and C called with 9♥8♥. The board runs out J♥T♠2♦2♣4♦, missing C's straight draw entirely.

The side pot goes to B: kings beat nine high, and A's hand plays no part in that comparison. The main pot goes to A: aces beat kings.

Follow B's money and the design of the rule shows itself. He lost $100 to the aces in the main pot, won $200 from C in the side pot, and finished the hand up $100 while holding the second-best hand at the table. Every dollar he won came from C, and every dollar he lost went to A, because his flop bet was only ever playing against the one opponent who could call it. A, holding the best hand, tripled her $100 and could not touch the rest.

That outcome is the whole reason side pots exist. Without them, a $100 stack could sit in a $500 pot, and every big stack at the table would be gambling against money that was never really matched.

One aside worth a detour, because the numbers surprise most players. Before the flop, the exact enumeration of that three-way matchup gives the aces 61.3%, the suited connector 22.0%, and the kings 16.7%. Kings are the second-best starting hand in the game and the worst hand in this pot, because they are dominated by the aces and share the big-card outs, while 9♥8♥ wins by making straights and flushes that beat both of them.

When two players are all in for different amounts

Add one layer and the same rule handles it. A is all in for $50, B is all in for $200, and C, who covers both, calls.

Match the shortest stack first: $50 from each of the three makes a $150 main pot that everyone is in. B's remaining $150 is matched only by C, so the side pot is $300 between those two. C's extra chips were never matched by anyone and never leave her stack.

At showdown the order is the same, side pot first. B and C compare for the $300; then all three compare for the $150. Any number of all-ins works this way: each all-in caps a pot, and every pot above the cap excludes the players who ran out of chips below it.

The unmatched-bet case is the same principle in miniature. If you bet $200 and the only player left calls all in for $80, the extra $120 was never matched and comes straight back to you before the hand is scored. Nobody wins chips that nobody could call.

Running it at a live table, and at your own

In a card room this is the dealer's problem. You will hear the phrase "making the pot right" as they pull the matched chips into the middle and stack the side pot separately, and your only job is to know which pots your hand is live for. If it is your first casino session, that is genuinely all you need.

At home, the arguments start when the pots are built at showdown instead of when the all-in happens. The fix is procedural: the moment someone is all in and two or more players are still betting, stop and build the main pot right then, physically separate, before another chip goes in. Chips that keep landing in one undivided pile turn into an accounting exercise five minutes later, with hands face up and money on the line, which is the worst possible time to do arithmetic. It is the same category of problem as vague blind levels or IOU buy-ins, and the solution is the same one we gave in the poker-night guide: decide the procedure before the cards are in the air.

When a multiway all-in confuses us anyway, we photograph the board, log the hand in PokerInk, and check the equities afterward with the odds calculator; the split is usually less controversial once everyone sees the numbers. The glossary entry compresses all of this to two lines, if you ever need to settle a table dispute from a phone.
