Players in a poker game act in turn, in clockwise rotation
(acting out of turn is a breach of etiquette and can negatively
affect other players). When it is a player's turn to act, the
first verbal declaration or action he takes binds him to his
choice of action; this is to prevent a player from changing
his action after seeing how other players react to his first
action.
A
player may fold by surrendering his cards (some
games may have specific rules--for example, in stud poker one
must turn one's upcards face down). A player may check by rapping
the table or making any similar motion. All other bets are made
by placing chips in front of the player, but not directly into
the pot (this is called "splashing" the pot, and is
also a breach of etiquette, because it prevents other players
from verifying the bet amount).
Open
The
act of making the first voluntary bet in a betting round is
called opening the round. On the first betting round, it is
also called opening the pot. Some poker variations have special
rules about opening a round that may not apply to other bets.
For example, a game may have a betting structure that specifies
different allowable amounts for opening than for other bets,
or may require a player to hold certain cards to open.
Call
To
call is to match a bet or a raise. A betting round ends when
all active players have bet an equal amount or no opponents
call a player's bet or raise. If no opponents call a player's
bet or raise, the player wins the pot and the hand is over.
The
second and subsequent calls of a particular bet amount are sometimes
called overcalls. A player calling a raise before he or she
has invested money in the pot in that round is cold calling.
For example, if in a betting round, Alice bets, Bob raises,
and Carol calls, Carol "calls two bets cold". A player
calling instead of raising with a strong hand is smooth calling,
a form of slow play.
In
public card rooms and casinos where verbal declarations are
binding, the word "call" is such a declaration. In
particular, the practice of saying "I call, and raise $100"
is considered a string raise and is not allowed. Saying "I
call" commits you to the action of calling, and only calling.
Note
that the verb "see" can often be used instead of "call":
"Bob saw Carol's bet", although the latter can also
be used with the bettor as the object: "I'll see you"
means 'I will call your bet'. However, terms such as "overseeing"
and "cold seeing" are not valid.
Check
If
no one has yet opened the betting round, a player may check,
which is equivalent to calling the current bet of zero. When
checking, a player declines making a bet; indicating that he
does not choose to open, but that he wishes to keep his cards
and retain the right to call or raise later in the same round
if an opponent opens. In games played with blinds, players may
not check on the opening round because they must either match
(or raise) the big blind or fold. A player with a live big blind
who chooses not to exercise his right to raise is said to check
his option. If all players check, the betting round is over.
A common way to signify checking is to tap the table with a
fist or an open hand.
Raise
To
raise is to increase the size of the bet required to stay in
the pot, forcing all subsequent players to call the new amount.
If the current bet amount is nothing, this action is considered
the opening bet. A player making the second (not counting the
open) or subsequent raise of a betting round is said to re-raise.
Standard
poker rules require that any raise must at least equal the amount
of the previous raise. For example, if a player in a spread-limit
or no-limit game bets $5, the next player may raise by another
$5 or more, but he may not raise by only $2, even if that would
otherwise conform to the game's betting structure. The primary
purpose of this rule is to avoid game delays caused by "nuisance"
raises (small raises of large bets that do not affect the bet
amount much but that take time). This rule is overridden by
table stakes rules, so that a player may in fact raise a $5
bet by $2 if that $2 is his entire remaining stake.
In
most casinos, fixed-limit and spread-limit games cap the total
number of raises allowed in a single betting round (typically
three or four, not including the opening bet of a round). For
example in a casino with a three-raise rule, if one player opens
the betting for $5, the next raises by $5 making it $10, a third
player raises another $5, and a fourth player raises $5 again
making the current bet $20, the betting is said to be capped
at that point, and no further raises beyond the $20 level will
be allowed on that round. It is common to suspend this rule
when there are only two players betting in the round (called
being heads-up), since either player can call the last raise
if they wish. Pot-limit and no-limit games do not have a limit
on the number of raises.
Fold
To
fold is to discard one's hand and forfeit interest in the current
pot. Folding may be indicated verbally or by discarding one's
hand face down into the pile of other discards called the muck.
In stud poker played in the United States, it is customary to
signal folding by turning all of one's cards face down. In casinos
in the United Kingdom, a player folds by giving his hand as
is to the "house" dealer, who will spread the hand's
upcards for the other players to see before mucking them.
It
is a serious breach of etiquette to fold out of turn, that is,
when it is not the folding player's turn to act, because this
can harm other players. For example, if there are three players
remaining and the first player in turn bets, the third player
folding out of turn gives valuable strategic information to
the second player (who is in turn at this point), to the detriment
of the bettor. In some games, even folding in turn when a player
is entitled to check (because there is no bet facing the player)
is considered an out of turn fold since it gives away information
to which other players would otherwise not be entitled. Finally,
if a player folds out of turn in a stud poker game, the player
in turn may demand that his upcards remain exposed until he
has completed his turn. When folding, concealed cards should
not be exposed unless no further betting is possible in the
hand (i.e., unless the fold awards the pot to the only remaining
player). A player is never required to expose his concealed
cards when folding prior to the showdown.
Forced
bets
All
poker games require some forced bets in order to create an initial
stake for the players to contest. The requirements for forced
bets, and the betting limits of the game (see below) are collectively
called the game's betting structure.
Ante
An
ante is a forced bet in which each player places an equal amount
of money or chips into the pot before the deal begins. In games
where the acting dealer changes each turn, it is not uncommon
for the players to agree that the dealer provides the ante for
each player. This simplifies betting, but causes minor inequities
if other players come and go or miss their turn to deal.
Blinds
A
blind or blind bet is a forced bet placed into the pot by one
or more players before the deal begins, in a way that simulates
bets made during play. The most common use of blinds as a betting
structure calls for two blinds: the player after the dealer
blinds about half of what would be a normal bet, and the next
player blinds what would be a whole bet. Sometimes only one
blind is used, and sometimes three. In the case of three blinds
(usually one quarter, one quarter, and half a normal bet amount),
the first blind goes "on the button", that is, is
paid by the dealer.
For
example, in a $2-$4 limit game, the first player to the dealer's
left (who, if not for the blinds, would be the first to act)
makes a blind bet of $1, and the next player in turn posts a
big blind of $2. After the cards are dealt, play begins with
the next player in turn (third from the dealer), who must either
call $2, raise, or fold. When the betting returns to the player
who blinded $1, he must equal the bet facing him (toward which
he may count his $1), raise, or fold. If there have been no
raises when action first gets to the big blind (that is, the
bet amount facing him is just the amount of the big blind he
posted), the big blind has the option to raise or check. This
right to raise (called the option) occurs only once: if his
raise is now called by every player, the first betting round
closes as usual.
In
some fixed-limit and spread-limit games, the big blind amount
may be less than the normal betting minimum. Players acting
after a sub-minimum blind have the right to call the blind as
it is, even though it is less than the amount they would be
required to bet, or they may raise the amount needed to bring
the current bet up to the normal minimum, called completing
the bet. For example, a game with a $5 fixed bet on the first
round might have blinds of $1 and $2. Players acting after the
blind may either call the $2, or raise to $5. After the bet
is raised to $5, the next raise must be to $10 in accordance
with the normal limits.

When
a player in the blinds leaves the game |
When
one or more players in the small or big blinds leaves the game,
an adjustment is required in the positioning of the blinds and
the button. The two most common tournament rules for handling
this situation are the dead button and the moving button rules.
In online card rooms, a simplified moving button rule is usually
employed. Note that other variations on these rules exist.
Dead
button rule
Under
the dead button rule, the big blind is posted by the player
due for it, and the small blind and button are positioned accordingly,
even if this means the small blind or the button is placed in
front of an empty seat, giving the same player the privilege
of last action on consecutive hands.
If
the small blind busts out (leaves the game), the button moves
to the seat vacated by the eliminated small blind. The player
who was the big blind now posts the small blind and the player
to his left posts the big blind. Since the button is now located
at an empty seat, the player who was the button will, in effect,
be the button once again.
If
the big blind busts out, the button moves to the player who
was the small blind and the player to the left of the eliminated
big blind posts the big blind. There is no small blind for that
hand. On the following deal, the button moves to the empty seat
vacated by the eliminated player and the two players to the
left post the normal blinds. Since the button is now located
at an empty seat, the player who was the original small blind
will, in effect, be the button once again.
If
both blinds bust out, the same player will effectively be the
button three hands in a row. The button moves to the now empty
seat vacated by the eliminated small blind and the player to
the left of the eliminated big blind posts the big blind. There
is no small blind for that hand. On the following deal, the
button moves to the next empty seat (the seat vacated by the
eliminated big blind player) and the two players to the left
post the normal blinds.
Moving
button rule
Under
the moving button rule, the button always moves forward so that
a player never has the right to act last for two consecutive
hands. The blinds adjust accordingly, which may result in more
than one small blind, and/or more than one big blind being posted
in a given hand.
These
rules are always followed when assigning the blinds:
The
button always moves forward to the next seat occupied by a player.
The
player two seats to the left of the button always posts a big
blind, as well as any players that the big blind has skipped
past.
Any
player that posted a big blind in the previous hand, must post
a small blind.
For
the following examples, consider a hand just finished with Alice,
Bob, Carol, David, and Ellen seated in order after the previous
hand's dealer. Alice was the small blind in the previous hand,
and Bob was the big blind.
Under
normal conditions, Alice will have the button the next hand,
Bob will post the small blind, and Carol will post the big blind.
If
Alice busts out, or steps away from the table, the button will
skip past the vacated seat to Bob. Bob will post his small blind
on top of the button. Carol and David will both post big blinds.
The
subsequent hand, Carol will have the button. Carol and David
will both post small blinds, and Ellen will post the big blind.
If
Bob busts out or leaves the table, the button will move to Alice.
Carol and David will both post big blinds.
The
subsequent hand, Carol will post a small blind on the button.
David will post a small blind and Ellen will post the big blind.
If
Alice and Bob both bust out, or step away from the game, the
button will skip ahead to Carol. Carol, David, and Ellen will
all post big blinds.
The
subsequent hand, David will have the button. Carol will post
a small blind behind the button, as well as David and Ellen
posting small blinds, and the player after Ellen posting the
big blind.
The
moving button system can cause irregular blinds for several
hands after a player leaves the game, and further complications
can arise if players bust out on consecutive hands. However,
the blinds will always eventually resolve to their normal positions.
Simplified
moving button rule
Under
the simplified moving button rule, normally used in on-line
card rooms, the button always moves forward to the next player
and the small and big blinds post in the two seats to the left
of the button. Players may miss blinds.
When
there are only two players
The
normal rules for positioning the blinds do not apply when there
are only two players at the table. The player on the button
is always due the small blind, and the other player must pay
the big blind. The player on the button is therefore the first
to act before the flop, but last to act for all remaining betting
rounds.
A
special rule is also applied for placement of the button whenever
the size of the table shrinks to two players. If three or more
players are involved in a hand, and at the conclusion of the
hand one or more players have busted out such that only two
players remain for the next hand, the position of the button
may need to be adjusted to begin heads-up play. The big blind
always continues moving to the left, and then the button is
positioned accordingly.
For
example, in a three-handed game, Alice is the button, Bob is
the small blind, and Carol is the big blind. If Alice busts
out, the next hand Bob will be the big blind, and the button
will skip past Bob and move to Carol. On the other hand, if
Carol busts out, Alice will be the big blind, Bob will get the
button and will have to pay the small blind for the second hand
in a row.
Bring-in
A
bring-in is a type of forced bet that occurs after the cards
are initially dealt, but before any other action. One player,
usually chosen by the value of cards dealt face up on the initial
deal, is forced to open the betting by some small amount, after
which players act after him in normal rotation.
The
bring-in is normally assigned on the first betting round of
a stud poker game to the player whose upcards indicate the poorest
hand. For example, in traditional high hand stud games and high-low
split games, the player showing the lowest card pays the bring-in.
In low hand games, the player with the highest card showing
pays the bring-in. The high card by suit order can be used to
break ties if necessary.
In
most fixed-limit and some spread-limit games, the bring-in amount
is less than the normal betting minimum. The player forced to
pay the bring-in may choose either to pay only what is required
or to make a normal bet. Players acting after a sub-minimum
bring-in have the right to call the bring-in as it is, even
though it is less than the amount they would be required to
bet, or they may raise the amount needed to bring the current
bet up to the normal minimum, called completing the bet. For
example, a game with a $5 fixed bet on the first round might
have a bring-in of $2. Players acting after the bring-in can
either call the $2, or raise to $5. After the bet is raised
to $5, the next raise must be to $10 in accordance with the
normal limits.
In
a game where the bring-in is equal to the fixed bet (this is
rare and not recommended), the game must either allow the bring-in
player to optionally come in for a raise, or else the bring-in
must be treated as live in the same way as a blind, so that
the player is guaranteed his right to raise on the first betting
round if he chooses.
Straddle
bets
A
straddle bet is an optional (voluntary) blind bet made by a
player before receiving his cards. Straddles are only used in
games played with blind structures. Straddles are normally not
permitted in tournament formats.
Live
straddle
The
player immediately to the left of the big blind may place a
live straddle blind bet. The straddle must be a raise over the
big blind. A straddle is a live bet; the player placing the
straddle effectively becomes the "bigger blind". Action
begins with the player to the left of the straddle. If action
returns to the straddle without a raise, the straddle has the
option to raise. The player to the left of a live straddle may
re-straddle by placing a blind bet raising the original straddle.
Mississippi
straddle
A
Mississippi straddle buys last action before the flop. House
rules permitting Mississippi straddles are common in the southern
United States. Usually, a Mississippi straddle can be made from
any position, although some house rules only permit the button
or the player to the right of the button to place a Mississippi
straddle. Like a live straddle, a Mississippi straddle must
be at least the minimum raise. Action begins with the player
to the left of the straddle. If, for example (in a game with
$10-$25 blinds), the button puts a live $50 on it, the first
player to act would be the small blind, followed by the big
blind, and so on. If action gets back to the straddle with no
raise, the straddle has the option of raising. The player to
the right of a Mississippi straddle may re-straddle by placing
a blind bet raising the original straddle.
Sleepers
A
sleeper is a blind raise placed from any position at the table
other than under the gun.
Limits
Betting
limits apply to the amount a player may open or raise, and come
in four common forms: no limit, pot limit (the two collectively
called big bet poker), fixed limit, and spread limit.
All
such games have a minimum bet as well as the stated maximums,
and also commonly a betting unit, which is the smallest denomination
in which bets can be made. For example, it is common for games
with $20 and $40 betting limits to have a minimum betting unit
of $5, so that all bets must be in multiples of $5, to simplify
game play. It is also common for some games to have a bring-in
that is less than the minimum for other bets. In this case,
players may either call the bring-in, or raise to the full amount
of a normal bet, called completing the bet.
Outside
of the United States, pot-limit and no-limit games are the most
common. Many American home games are played with a spread limit,
while casino games are often played with spread or fixed limits,
though many casinos may have pot-limit or no-limit games as
well. Fixed-limit and spread-limit games emphasise the skill
of estimating odds, whereas pot-limit and no-limit games emphasize
the skills of game theory and psychology. Almost all poker players
believe that pot-limit and no-limit poker involve more skill
than fixed-limit play. A few prominent players, most notably
Mason Malmuth, believe that the richer tactics make fixed limit
more skilled. Although the main event at the World Series of
Poker is played no limit, most high stakes cash games are fixed
limit, so it is unclear which format is the experts' choice.
Fixed
limit
In
a game played with a fixed-limit betting structure, a player
chooses only whether to bet or not - the amount is fixed by
rule. To enable the possibility of bluffing, the fixed amount
generally doubles at some point in the game. This double wager
amount is referred to as a big bet.
For
example, a four-round game called "20 and 40 limit"
(usually written as $20/$40) may specify that each bet in the
first two rounds is $20, and that each big bet used in the third
and fourth rounds is $40. This amount applies to each raise,
not the total amount bet in a round, so a player may bet $20,
be raised $20, and then re-raise another $20, for a total bet
of $60, in such a game.
Maximum
number of raises
Most
fixed-limit games will not allow more than a predefined number
of raises in a betting round. The maximum number of raises depends
on the casino house rules, and is usually posted conspicuously
in the card room. Typically, an initial bet plus three raises,
or a bet and four raises, are allowed.
Consider
this example in a $20/$40 game, with a posted limit of a bet
and three raises. During a $20 round with three players, play
could proceed as follows:
Player
A bets $20.
Player
B puts in another bet, raises another $20, making it $40 to
play.
Player
C puts in a third bet, raising another $20 on that, thus making
it $60 to play.
Player
A puts in the fourth bet (she is usually said to cap the betting).
Once
Player A has made her final bet, Players B and C may only call
another two and one bets (respectively); they may not raise
again because the betting is capped.
A
common exception in this rule practiced in some card rooms is
to allow unlimited raising when a pot is played heads up (when
only two players are in the hand at the start of the betting
round). Usually, this has occurred because all other players
have folded, and only two remain. Many card rooms will permit
these two players to continue re-raising each other until one
player is all in.
Kill
game
Sometimes
a fixed-limit game is played as a kill game. Such a game is
played with an additional blind, called the kill blind. The
kill blind can be posted from any position at the table. The
amount posted is typically twice the typical blind for that
game. For example, in a $20/$40 game, the large blind is typically
$20. If this game were played with a full kill, the kill blind
would be $40. It is also common to find a game with a half kill.
For example, when the kill is active in $4/$8 game with a half
kill, the game is played at a $6/$12 limit. A pot built from
this betting structure is known as a kill pot.
In
some card rooms, the player with the kill blind acts last after
the big blind regardless of where they are seated in relation
to the dealer button. For example, in a five-handed game where
player E has earned the kill button and player A is the dealer,
the order of action is player D, player A, player B (the small
blind), player C (the big blind), player E (the kill blind).
After the flop, betting returns to normal.
Rules
on how the kill is activated vary. Sometimes the kill is activated
by the previous pot being over a particular value. One common
value is ten times the value of the large bet (in a $20/$40
game, the kill would be active if the previous pot won was greater
than $400). The winner of that pot is required to post the kill
blind for the next hand. Another common way a kill is activated
is when a single player wins two pots in a row, requiring the
winner to post a kill blind on the next hand. The kill will
typically remain active if the player with the kill blind continues
to win consecutive hands. If a player has won the previous hand
and splits the pot with another player, that may also activate
a kill hand. If a pot is split and neither player has won the
previous hand, winning the pot of the next hand does not typically
activate a kill hand.
The
term kill, when used in this context, should not be confused
with killing a hand, which is a term used for a hand that was
made a dead hand by action of a game official.
Spread
limit
A
game played with a spread-limit betting structure allows a player
to raise any amount within a specified range.
For
example, a game called "one to five limit" allows
each bet to be anywhere from $1 to $5 (subject to other betting
rules). These limits are typically larger in later rounds of
multi-round games. For example, a game might be "one to
five, ten on the end", meaning that early betting rounds
allow bets of $1 to $5, and the last betting round allows bets
of $1 to $10.
Playing
spread-limit requires some care to avoid giving easy tells with
one's choice of bets. Beginners frequently give themselves away
by betting high with strong hands and low with weak ones, for
instance. It is also harder to force other players out with
big bets.
Pot
limit
A
game played with a pot-limit betting structure allows any player
to raise up to an amount equal to the size of the whole pot
before the raise.
For
example, let us assume that there is $10 in the pot
at the start of a betting round. The first player may open the
betting for up to $10. If he does in fact open for $10, the
next player may raise to $40 (after calling the $10 bet, the
total amount of the pot is $30, so he may raise $30). The third
player would be entitled to raise to $140 (after calling $40,
the pot would contain $100, thus he may raise $100). Any player
may also raise less than the maximum so long as the amount of
the raise is equal to or greater than any previous bet or raise
in the same betting round.
Some
pot-limit games make exceptions to the method described
above when calculating the maximum raise in the betting round
before the flop:
Some
structures treat the little blind as if it were the same size
of the big blind in computing pot size. In such a structure,
a player can open for a maximum of four times the size of the
big blind. For example, if the blinds are $5 and $10, a player
may open with a raise to $40. (The range of options is to either
open with a call of $10, or raise in increments of five dollars
to any amount from $20 to $40.) Subsequent players also treat
the $5 as if it were $10 in computing the pot size, until the
big blind is through acting on the first betting round.
If
the action folds all the way around to the small blind, the
maximum amount the small blind can raise is also not universally
agreed upon. Some games treat the big blind as a "raise"
of the small blind for the purpose of calculating the maximum
raise—the small blind is allowed to call the big blind,
and then make a pot sized raise of twice the big blind, for
a total bet of three times the big blind. Other games treat
the blinds as dead money for the purpose of calculating the
raise, and allow the small blind to make the same size raise
as any other player, i.e. a total bet of three times the big
blind plus the small blind.
Because
of the disparity in methods of calculation, and the fact that
the issue is certain to come up often, most major tournaments
will announce the amount of the maximum opening raise to all
players any time the betting limits are increased.
No
limit
A
game played with a no-limit betting structure allows each player
to raise any amount of his stake at any time (subject to the
table stakes rules and any other rules about raising).
Table
stakes rules
All
casinos and many home games play poker by what are called table
stakes rules, which state that each player starts each deal
with a certain stake, and plays that deal with that stake. He
may not remove money from the table or add money from his pocket
during the play of a hand. Nor is a player allowed to hide or
misrepresent the amount of his stake from other players; he
must truthfully disclose the amount when asked. This requires
some special rules to handle the case when a player is faced
with a bet that he cannot call with his available stake.
"All
in"
When
a player is faced with a current bet amount that he has insufficient
remaining stake to call and he wishes to call (he may of course
fold without the need of special rules), he bets the remainder
of his stake and declares himself all in. He may now hold onto
his cards for the remainder of the deal as if he had called
every bet, but he may not win any more money from any player
above the amount of his bet.
For
example, let's assume that the first player in a betting round
opens for $20, and the next player to bet has only $5 remaining
of his stake. He bets the $5, declaring himself all in, and
holds onto his cards. The next player in turn still has the
$20 bet facing him, and if he can cover it he must call $20
or fold. If he calls $20, thus ending the betting round, instead
of collecting all bets into the central pot as usual, the following
procedure is applied: since there is an all-in player with only
$5 bet, his $5, and $5 from each of the other players, is collected
into the central pot (now called the main pot), as if the final
bet had been only $5. This main pot (which may include any antes
or bets from previous rounds) is the most the all-in player
is eligible to win.
The remaining money from the still-active bettors, in this case
$15 apiece, is collected into a side pot that only the players
who contributed to it are eligible to win. If there are further
betting rounds, all bets are placed into the side pot while
the all-in player continues to hold his cards but does not participate
in further betting. Upon the showdown, the players eligible
for the side pot—and only those players—reveal their
hands, and the winner among them takes the side pot, regardless
of what the all-in player holds (indeed, before he even shows).
After the side pot is awarded, the all-in player then shows
his hand, and if it is superior to all others shown, he wins
the main pot (otherwise he loses as usual).
There
is a strategic advantage to being all in: a player cannot be
bluffed, because he is entitled to hold his cards and see the
showdown without risking any more money. Opponents who continue
to bet after the player is all in can still bluff each other
out of the side pot, which is also to the player's advantage
since bluffing between opponents may reduce his competition.
But these advantages are offset by the disadvantage that the
player cannot win any more money than what his stake can cover.
Some
players may choose to buy into games with a "short stack",
a stack of chips that is relatively small for the stakes being
played, with the intention of going all in and not having to
make any further decisions.
All-in
before the deal
If
a player does not have sufficient money to cover the ante and
blinds due, that player is automatically all-in for the coming
hand. Any money the player holds must be applied to the ante
first, and if the full ante is covered, the remaining money
is applied towards the blind.
If
a player is all-in for part of the ante, or the exact amount
of the ante, an equal amount of every other player's ante is
placed in the main pot, with any remaining fraction of the ante
and all blinds and further bets in the side pot.
If
a player is all-in for part of a blind, all antes go into the
main pot. Players to act must call the complete amount of the
big blind to call, even if the all-in player has posted less
than a full big blind. At the end of the betting round, the
bets and calls will be divided into the main pot and side pot
as usual.
For
example, Alice is playing at a table with 10 players in a tournament
with an ante of $100 and blinds of $400/$800. Alice is due the
big blind but she only has $800. She must pay the $100 ante
and apply the remaining $700 towards the big blind, and she
is all-in. Bob, next to act, calls $800, the full big blind
amount. Carol raises to $1600 total. All remaining players fold,
the small blind folds, and Bob folds. The amount in the main
pot is $1000 (the sum of all antes) plus the full $400 small
blind since Alice had this amount covered, plus $700 from Alice
and every other player who called at least that amount, namely
Bob and Carol. The main pot is therefore $1000+$400+$2100=$3500.
The side pot of $1000 ($100 in excess of Alice's all-in from
Bob, and $900 in excess of Alice's all-in from Carol) is paid
immediately to Carol when Bob folds.
Incomplete
bet or raise
If
a player goes all in with a bet or raise rather than a call,
another special rule comes into play. There are two options
in common use: pot-limit and no-limit games usually use what
is called the full bet rule, while fixed-limit and spread-limit
games may use either the full bet rule or the half bet rule.
The full bet rule states that if the amount of an all-in bet
is less than the minimum bet, or if the amount of an all-in
raise is less than the full amount of the previous raise, it
does not constitute a "real" raise, and therefore
does not reopen the betting action. The half bet rule states
that if an all-in bet or raise is equal to or larger than half
the minimum amount, it does constitute a raise and reopens the
action.
For
example, a player opens the betting round for $20,
and the next player has a total stake of $25. He may raise to
$25, declaring himself all in, but this does not constitute
a "real" raise, in the following sense: if a third
player now calls the $25, and the first player's turn to act
comes up, he must now call the additional $5, but he does not
have the right to re-raise further. The all-in player's pseudo-raise
was really just a call with some extra money, and the third
player's call was just a call, so the initial opener's bet was
simply called by both remaining players, closing the betting
round (even though he must still equalize the money by putting
in the additional $5). If the half bet rule were being used,
and the all-in player had raised to $30 instead of $25, then
that raise would count as a genuine raise and the first player
would be entitled to re-raise if he chose to (this would create
a side pot for the amount of his re-raise and the third player's
call, if any).
In
a game with a half bet rule, a player may complete an incomplete
raise, if that player still has the right to raise (in other
words, if that player has not yet acted in the betting round,
or has not yet acted since the last full bet or raise). The
act of completing a bet or raise reopens the betting to other
remaining opponents.
For
example, four players are in a hand, playing with a limit betting
structure and a half bet rule. The current betting round is
$20. Alice checks, and Bob checks. Carol goes all-in for $5.
David, still to act, has the following options: fold, call $5,
or complete the bet to a total of $20. If David calls the $5,
Alice and Bob only have the option of calling or folding; neither
can raise. But if David completes, either of them could raise.
Opening
all-in hands
When
all players are all in, or one player is playing only against
opponents who are all in, no more betting can take place. Some
casinos and many major tournaments require that all players
still involved open, or immediately reveal, their hole cards
in this case—the dealer will not continue dealing until
all hands are flipped up. Likewise, any other cards that would
normally be dealt face down, such as the final card in seven-card
stud, may be dealt face-up. This rule discourages a form of
collusion called "chip dumping", in which one player
deliberately loses his chips to another to give that player
a greater chance of winning the tournament.
Open
stakes
The
alternative to table stakes rules is called "open
stakes", in which players are allowed to buy more
chips during the hand and even to borrow money (often called
"going light"). This may be appropriate for home or
private games but is never allowed in casinos.
First,
a player may go all in in exactly the same manner as in table
stakes if he so chooses, rather than adding to his stake or
borrowing. Because it is a strategic advantage to go all in
with some hands while being able to add to your stake with others,
such games should strictly enforce a minimum buy-in that is
several times the maximum bet (or blinds, in the case of a no-limit
or pot-limit game). A player who goes all in and wins a pot
that is less than the minimum buy-in may not then add to his
stake or borrow money during any future hand until he re-buys
an amount sufficient to bring his stake up to a full buy-in.
A
player may instead choose to buy chips with cash out-of-pocket
at any time, even during the play of a hand, and his bets are
limited only by the specified betting structure of the game.
Finally,
a player may also borrow money by betting with an IOU, called
a "marker", payable to the winner of the pot. In order
to bet with a marker, all players still active in the pot must
agree to accept the marker. If any player refuses to accept
a marker, the bettor may bet with cash out-of-pocket or go all-in.
A player may also borrow money from a player not involved in
the pot, giving him a personal marker in exchange for cash or
chips, which the players in the pot are then compelled to accept.
A player may borrow money in order to call a bet during a hand,
and later in the same hand go all-in in the face of further
betting; but if a player borrows money in order to raise, he
forfeits the right to go all-in later in that same hand--if
he is re-raised, he must borrow money to call, or fold.
Just
as in table stakes, no player may remove chips or cash from
the table once they are put in play (except small amounts for
refreshments, tips, and such)--this includes all markers, whether
one's own or those won from other players.
Players
should agree before play on the means and time limits of settling
markers, and a convenient amount below which all markers must
be accepted to simplify play.
