What is an All-In in Poker?

An all-in in poker is a bet, call, or raise that puts every chip you have left into the pot. It is the maximum possible wager in a hand. When you go all-in, you cannot be forced to fold later, but you also cannot win more than what you put in from each opponent. The key distinction: an all-in is not a separate action type—it is simply a bet of your entire stack. Many players confuse it with a call, but a call matches a bet; an all-in can be a call if you only have enough to match, but it is usually a raise because you are putting in more than the current bet.

What is an All-In and What It Is Not

An all-in is a wager of all your remaining chips. It can happen at any point in a hand: preflop, on the flop, turn, or river. When you go all-in, you are either betting, raising, or calling with your entire stack. If you have fewer chips than the current bet, you can still call all-in for less, creating a side pot for the remaining players.

What it is not: an all-in is not a separate action like a check or fold. It is not a way to force a showdown—your opponent can still fold. It is not a guarantee of winning the pot; you can still lose to a better hand. It is also not a bluff only; it can be a value bet with a strong hand.

How to Use an All-In: When and How Much

You go all-in when you want to maximize value with a strong hand, bluff with fold equity, or protect a vulnerable hand. The amount is always your entire stack. There is no partial all-in; you either put in all your chips or you don't. If you have a bigger stack than an opponent, you can only win from them up to their stack size; the rest goes into a side pot.

Worked stack example

1. Take the all-in: You are on the river with the nut flush. The pot is 100bb. Your opponent bets 50bb, and you have 200bb behind. You go all-in for 200bb, putting maximum pressure on your opponent to call with a worse hand. This is a value shove.

2. Don't take the all-in: You are in the early stages of a tournament with a medium pair. The pot is 10bb, and you have 80bb. An opponent raises to 3bb. You do not have a strong enough hand to risk your tournament life, so you fold. Going all-in here would be reckless.

When Not to Use an All-In

Do not go all-in when you have a marginal hand and no fold equity. For example, if you are against a calling station, a bluff all-in is unlikely to work. Also, avoid all-ins when you are deep-stacked and the pot is small; you risk too much to win too little. In tournaments, avoid all-ins when you are not short-stacked and have a comfortable stack to play postflop.

The Next Decision After an All-In

If your all-in is called, the hand proceeds to showdown (or the next street if there are still cards to come). If your all-in is not called, you win the pot immediately. If you are facing an all-in, you must decide to call, fold, or re-raise (if you have more chips). Your decision depends on your pot odds, your hand strength, and the opponent's range.

Leaks on this stack decision

• Going all-in with a draw without fold equity: If your opponent is unlikely to fold, you are risking too much for a draw that may not hit.
• Shoving too wide in tournaments: Many players shove with any ace or any pair, but this can be -EV if opponents call with better ranges.
• Not considering side pots: When you are all-in for less than the current bet, you may not be eligible for the main pot if you lose to a side-pot player.
• Using all-in as a scare tactic: Some players go all-in to intimidate, but this is rarely profitable against skilled opponents.

Frequently Asked Questions

What happens if two players go all-in and one has more chips?

If one player has more chips, the player with the smaller stack is all-in for their entire stack, and the larger stack can only win up to that amount from the smaller stack. The excess chips go into a side pot, which is contested only by the players who have chips remaining.

Can you go all-in when you have no chips left?

No, you cannot go all-in if you have no chips. You must have at least one chip to make a bet. If you have zero chips, you are out of the hand.

Is an all-in a raise or a call?

An all-in can be either. If you are matching the current bet with your entire stack, it is a call. If you are putting in more than the current bet, it is a raise. The action is still considered a bet, call, or raise, but the amount is your entire stack.

What is a side pot in an all-in situation?

A side pot is created when one or more players are all-in for less than the current bet. The main pot contains the chips from all players up to the amount of the shortest all-in stack. The side pot contains additional chips from players who have more chips, and it is contested only by those players.
