Many poker players get confused about all in poker rules and end up making costly mistakes at the table. Going all in happens in about 15% of poker hands in tournament play, making it one of the most common situations you’ll face.
This guide breaks down every rule, scenario, and strategy you need to master all-in situations in Texas Hold’em and other poker games. You’ll never second-guess an all-in decision again.
What Does “All In” Mean in Poker?

Now that you understand the basics, let’s explore what “all in” actually means in poker games.
Going all in means you bet every chip you have on the table. You push your entire stack forward and commit all your money to the current hand. This action creates a main pot that includes your total bet amount.
Other players can still bet more money, but you cannot win more than what you contributed to each pot. In no limit hold’em and other poker variants, this rule protects players with smaller stacks from losing more than they brought to the table.

The table stakes rule governs all-in situations in cash games and poker tournaments. You can only bet the chips sitting in front of you at the start of each hand. Players cannot reach into their pockets for more money during active play.
This creates fair betting conditions where your stack size determines your maximum risk. Side pots form when players have different stack sizes and multiple people stay in the hand after someone goes all in.
Rules for All-In Situations
All-in rules change based on how many players stay in the hand. The betting structure and table stakes create different situations that affect how the main pot and side pot work.
All-In with Two Players
All-in situations with two players create the simplest scenario in poker. Both players put their remaining chips into the main pot. The player with fewer chips can only win up to the amount they contributed from each opponent.
No side pot forms since only two players compete for the chips.
Texas holdem and no-limit hold’em games make these situations common. The short stack player risks their entire stack against their opponent. Both players reveal their cards after the betting ends.
The dealer completes the board by dealing the remaining community cards. The best five-card hand wins the entire pot. Cash games and poker tournaments both use these same basic rules for heads-up all-ins.
All-In with Multiple Players and Side Pots
Multiple players going all in creates side pots that split the action. The main pot includes chips that every player can win. Players with more chips create side pots for the extra money.
Each side pot only includes players who contributed to that specific pot.
Side pots form based on stack sizes and betting amounts. A short stack player going all in for 500 chips creates a main pot of 1,500 chips if three players call. The two remaining players with bigger stacks can keep betting.
Their extra bets form a side pot that only they can win. The all-in player can only win the main pot, even with the best hand.
How to Calculate Side Pots
Side pots form during all-in situations in no-limit hold’em and pot-limit omaha games. Players with different stack sizes create separate betting pools that determine winnings.
- Identify the smallest all-in amount among all players involved in the hand. This amount becomes the base for calculating the main pot in poker tournaments and cash games.
- Multiply the smallest all-in amount by the total number of players who contributed chips. Add any existing pot money from previous betting rounds to get the main pot total.
- Calculate remaining chips from players who bet more than the smallest all-in amount. These extra chips form the first side pot between eligible players only.
- Create additional side pots if three or more players have different all-in amounts. Each side pot includes only players who contributed that specific amount or more.
- Determine which players can win each pot based on their chip contributions. Short stack players can only win the main pot, while bigger stacks compete for side pots.
- Award the main pot to the best hand among all players in the showdown. Side pots go to the best hands among eligible players for each specific pot.
- Handle folded players by removing them from all pot calculations. Their contributed chips remain in the pots they helped create before folding.
- Apply table stakes rules to ensure no player risks more than their available chips. Big blinds and antes count toward each player’s total contribution amount.
Common Scenarios for Going All In
Players face three main situations where going all in becomes the smart play. These moments can make or break your poker session and require quick thinking to maximize your chips.
Short-Stacked in a Tournament
Short stacks in tournament poker face constant pressure to make moves. Your chip count drops below ten big blinds, and survival becomes critical. Going all in becomes your primary weapon to stay alive and build your stack back up.
Tournament poker demands aggressive play from short stacks because blinds increase regularly.
Stack sizes under five big blinds leave you with limited options. You must push all in with decent hands before your chips disappear completely. Cash games allow you to rebuy chips, but tournaments offer no second chances.
Smart short stack play focuses on finding spots where your hand has good equity against opponents’ calling ranges. Pick your battles carefully and avoid marginal situations that could end your tournament run.
Applying Pressure in Cash Games
Cash games offer different opportunities than tournaments for strategic all-in moves. Players can apply pressure with their entire stack to force difficult decisions from opponents.
Going all-in in no-limit hold’em cash games works best against opponents who play too tight. You can target players who fold too often to big bets. This strategy works well when you have a strong hand or a good semi-bluff.
The key is picking the right spots where your opponent likely holds a marginal hand. I’ve seen players double their stack by pushing all-in against tight opponents who can’t call without premium hands.
Table stakes rules protect you from losing more than what’s in front of you, making calculated all-in moves less risky than they appear.
Committed Pots
Committed pots happen in no-limit hold’em games where you have already invested so many chips that folding becomes a bad choice. Your pot odds make calling the right move, even with a weak hand.
This situation often occurs in cash games where the betting gets heavy on later streets. Players with short stacks face this problem more often than those with deep chip counts.
Smart players recognize committed pot situations before they develop. You need to think about future betting rounds before you put chips in the main pot. Many poker tournaments see players get trapped in these spots because they fail to plan ahead.
The key is understanding your stack size compared to the pot size at each betting round.
Let’s explore the common mistakes players make in these all-in situations.
Mistakes to Avoid When Going All In
Going all in at the wrong time can cost you big money. Smart players avoid these common mistakes that drain their bankrolls in cash games and poker tournaments.
- Moving all in with weak hands just because you have a short stack. Players often panic and shove with any two cards instead of waiting for better spots.
- Failing to calculate pot odds before committing your entire stack. Many players ignore the math and make emotional decisions that hurt their long-term results.
- Going all in without considering your table image and opponent tendencies. Tight players get more folds than loose players when they shove.
- Pushing all in too early in tournaments when the big blind is still small. Your stack has more value when blinds are low.
- Making all-in moves without proper bankroll management in cash games. One bad session can wipe out weeks of profits.
- Shoving all in as a bluff against calling stations who rarely fold. These players will call with marginal hands and bust your bluffs.
- Going all in with drawing hands that have poor implied odds. Semi-bluffs work better when you have fold equity and good pot odds.
- Moving all in in fixed limit games where the betting structure limits your fold equity. Save your big moves for no-limit hold’em games.
- Pushing all in without considering side pot situations in multi-way hands. You might win the main pot but lose a bigger side pot to another player.
FAQs About All In Poker Rules
Many players face confusion about all-in situations during poker tournaments and cash games. These questions come up most often at the table.
- Can you go all in with less than the big blind? Yes, you can push your entire short stack even if it’s smaller than the big blind. Other players must still call the full big blind amount to stay in the hand.
- What happens if two players go all in with different stack sizes? The player with fewer chips creates the main pot. Any extra betting between remaining players forms a side pot that the shorter stack cannot win.
- Do you have to show cards when going all in? No, you only show cards if called or if you reach showdown. Folding opponents never see your cards in no-limit hold’em games.
- Can you go all in out of turn? No, acting out of turn violates betting rules. The dealer will usually make you take back the action and wait for your proper turn.
- What if you accidentally put in more chips than you have? Table stakes rules protect you. You can only lose the chips you brought to the table at the start of the hand.
- Can you add chips during a hand after going all in? No, you cannot add chips once a hand begins. This rule prevents players from gaining unfair advantages during active play.
- What happens if you go all in and someone raises behind you? Other players can still raise each other. You remain eligible for the main pot but cannot win any additional side pot money.
- Do antes count toward your all-in amount? Yes, antes and blinds count as part of your stack. You must include these forced bets when calculating your total chips.
