Poker Betting Rules: Limits, Raises and All-Ins

Rules · Casino Poker

Every poker betting rule follows from one principle: table stakes. You can only win or lose the chips that are in front of you at the start of a hand, you cannot add to them mid-hand, and you cannot be forced out of a pot because somebody has a bigger stack. Blinds, minimum raises, pot limits and side pots are all just consequences of that.

This is a mechanics page. The numbers below are the ones that get misapplied at live tables and cost people pots they were entitled to.

Table stakes and the chips in front of you

• Only chips on the table play. Money in your pocket is not in play, and you may not reach for it during a hand. This is often called “no pocket play”.
• You can always call for your whole stack. If you have $50 and face a $300 bet, you may call all-in for $50 and contest the portion of the pot you have matched. Nobody can bet you off a hand simply by having more chips.
• You may add chips only between hands, in a cash game. Tournament stacks are fixed apart from rebuys and add-ons where the structure offers them — the practical differences are covered in poker tournaments vs cash games.

Blinds and antes

Forced bets exist so that there is always something worth playing for.

In hold’em the blinds are live: the big blind has already made the minimum bet, so if nobody raises, they get the option to check or raise when the action comes back around. A straddle is a voluntary extra blind, usually double the big blind, which moves the effective minimum bet up for that hand.

In seven-card stud there are no blinds at all — every player antes and the lowest exposed card must post the bring-in.

Minimum bet and minimum raise

Two rules govern every raise in no-limit and pot-limit:

Minimum bet = the size of the big blind.

Minimum raise = the size of the previous bet or raise.

The second one is where people get it wrong. A raise must increase the bet by at least as much as the last increase, not by the total on the table.

Worked example, $1/$2 no-limit:

• Player A raises to $7. The big blind was $2, so the increase is $5.
• Player B’s minimum raise is $5 on top: $12.
• Player B instead makes it $20. That increase is $13.
• Player C’s minimum raise is now $13 on top: $33.
• If Player C makes it $33, the next minimum is another $13, to $46.

The increment only ever goes up during a round, and it resets to the big blind on the next street. Note that a call is not a raise — three players calling $7 does not change anything about the next minimum.

No-limit, pot-limit and fixed-limit

Fixed-limit uses two bet sizes. In a $2/$4 limit Hold’em game, every bet and raise is $2 on the first two betting rounds and $4 on the last two. Rounds are also capped, usually at a bet plus three raises, after which no further raises are allowed. Because the price is fixed, the game is about frequency rather than sizing — the structure used in five-card draw and traditional stud.

How a pot-limit maximum is actually calculated

The maximum raise in pot-limit is the size of the pot after you call. Say it as a three-step procedure and it stops being confusing:

1. Total the pot as it stands.
2. Add every bet currently on the table.
3. Add the amount you would have to call.

That total is your maximum raise. Your maximum total is that number plus your call.

Example 1 — a pot-sized preflop raise. Pot-limit Omaha, $1/$2. The pot is $3 in blinds. You are first to act. Your call is $2, which makes the pot $5, so your maximum raise is $5 on top of the call. You may raise to $7. That is why the standard opening raise in PLO is 3.5 big blinds rather than 3.

Example 2 — raising a flop bet. The pot is $100 and your opponent bets $50. The table now holds $150. Your call is $50, which would take the pot to $200, so your maximum raise is $200 on top. You may raise to $250 total.

Example 3 — a bet and a caller in front of you. The pot is $40. Player A bets $20 and Player B calls $20, putting $80 on the table. Your call is $20, taking the pot to $100, so your maximum raise is $100 on top. You may raise to $120 total.

If you announce “pot”, the dealer calculates it for you and the amount is binding. The same arithmetic applies throughout Omaha, which is where you will actually use it.

All-in and side pots

A side pot is created whenever a player is all-in for less than the other players want to bet. The rule is simple: you can only win, from each opponent, as much as you yourself put in.

Three-player worked example. $1/$2 no-limit. Stacks: A has $50, B has $120, C has $300.

• A moves all-in for $50.
• B re-raises all-in for $120.
• C calls $120.

The dealer now splits the money:

C’s remaining $180 was never matched by anyone, so it stays in front of them and is not at risk. Total wagered: $50 + $120 + $120 = $290, which is exactly $150 + $140.

The outcomes:

• A has the best hand: A wins the $150 main pot. The $140 side pot goes to whichever of B and C has the better hand. A cannot win a chip of it.
• B has the best hand: B wins both pots, $290.
• C has the best hand: C wins both pots, and finishes the hand up $170 on the two opponents’ contributions.

Two procedural points: side pots are awarded before the main pot, in reverse order of creation, and a player who is all-in still has full showdown rights — they simply have no further betting decisions to make.

How you go all-in. The Tournament Directors Association (TDA) tightened this for tournaments at its 2026 summit, according to PokerNews and PokerOrg: you put in all of your chips or none of them. Push the whole stack forward or say “all-in”. You can no longer toss out one or two chips and declare all-in; the dealer is to push those chips back and place the all-in button, because the next player can mistake those chips for the whole bet. Keeping one chip back on purpose is still allowed as a strategic choice, and rooms should no longer force that player all-in, but the chip may not be hidden and dealers are to announce it.

All-in for less than a full raise

This is the ruling most commonly got wrong at a home game.

$1/$2 no-limit. Player A bets $10. Player B moves all-in for $16. That is an increase of only $6, where a full raise would need $10.

An all-in for less than a full raise does not reopen the betting to a player who has already acted.

So Player A may call the extra $6 or fold, and may not re-raise. Players who have not yet acted still face a live raise and may fold, call $16, or raise. If B had gone all-in for $20 or more — a full raise — the betting reopens completely and A could re-raise.

One honest caveat: the exact minimum raise size for a player still to act after an incomplete all-in is one of the very few rules that genuinely varies between cardrooms. Ask the dealer rather than assuming.

String bets, verbal declarations and the one-chip rule

• A verbal declaration in turn is binding. Say “raise to forty” and you are raising to forty, whatever chips you then put in. If you both speak and move chips, whichever comes first defines the bet; if they are simultaneous, a clear and reasonable verbal declaration takes precedence, otherwise the chips play.
• No string bets. Move your chips in one motion, or announce the amount first. Putting chips forward, then going back to your stack for more, is a string bet.
• The one-chip rule. If there is a bet in front of you and you silently put in a single chip larger than the bet, it is a call and you get change. To raise with one chip you must say “raise” first.
• A single chip when nobody has bet is a bet of the full chip. Sliding out a $100 chip first to act is a $100 bet, not a $2 one.
• Undersized raises get rounded up. If you push out at least half of a minimum raise beyond the call, the standard ruling is that you must complete it to the full minimum raise; anything less is ruled a call.
• Acting out of turn is binding if the action to you does not change. If somebody bets in front of you after you announced a check, your check may be withdrawn, and you regain all your options — call, raise or fold. Heads-up is the exception under the changes agreed at the 2026 TDA summit, as reported by PokerNews and PokerOrg: a player who checks or calls out of turn may no longer bet or raise once the action changes, only call or fold.

Why the mechanics matter

Bet sizing is not decoration — it is the price your opponent has to pay, and the price sets whether their call is profitable. A half-pot bet asks for 25% equity, a pot-sized bet asks for 33.3%, and a two-times-pot overbet asks for 40%. That relationship is the whole subject of pot odds, and the draws being priced are listed in the poker outs chart.
