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.

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 his raise is equal to or greater than the immediately previous bet or raise.

In pot-limit hold’em and pot-limit Omaha, many 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.

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).

In poker, a drawing hand is a hand that is not yet “complete”; that is, one which does not yet rank highly, but which may do later, depending on what cards a player receives. This contrasts with a “made hand” – a hand which is already somewhat strong.

An illustrative example from Texas Hold ‘em: if Alice holds A♣ K♣, Bob holds 6♦ 7♦, and the flop comes 5♠ 8♠ K♥, then Alice has a fairly strong “made hand” (a pair of Kings, with an Ace kicker), while Bob has a drawing hand: an open-ended straight draw. If allowed to see the final two community cards, Bob can expect to catch a 4 or a 9 (thus completing his straight and winning) about a third of the time.

Whether to continue with a drawing hand is usually a function of pot odds and implied odds. Typically, if a player with a strong “made hand” suspects another player of being “on a draw”, the player with the made hand will make a strong bet, so that it is mathematically incorrect for the other player to “chase”.

One possible algorithm for shuffling cards without the use of a trusted third party is to use a commutative encryption scheme. A commutative scheme means that if some data is encrypted more than once, the order in which you decrypt this data will not matter.

Example: Alice has a plaintext message. She encrypts this, producing a garbled ciphertext which she gives this to Bob. Bob encrypts the ciphertext again, using the same scheme as Alice but with another key. When decrypting this double encrypted message, if the encryption scheme is commutative, it will not matter who decrypts first.
