texas hold em poker rules

BETTING LIMITS

39.    Table stakes, (a) In any poker game except one with fixed limits, i.e., in any pot limit, doubling-up or no-limit game, a player who has not enough chips to call the preceding bets and who cannot obtain more chips may stay in for the showdown by betting all the chips he has left. If there are other players in the pot and they wish to continue betting, their bets above this amount go in a "side pot" in which the short player has no interest. Play continues normally until there is a showdown, when the player who was short competes on even terms for that part of the pot to which he contributed in full.

(b)    A player in a table stakes game may obtain additional chips from the banker, and add them to his stack on the table, only in the period between a showdown and the beginning of the next deal. He may at no time reduce the number of chips he has in front of him, by cashing them in or by removing them from his stack, except when he leaves the game.

(c)   A player who is tapped and calls remains in the pot until the showdown,  drawing cards on even terms with  the other players, without further contributions to the pot. If he has the best hand at the showdown, he takes the main pot. He has no interest in any side pots.

(d)   A player who drops rather than call a bet in a side pot must discard his hand and relinquishes his interest in all pots.

POKER PROBABILITIES

I said before that the higher mathematics of poker are not very important. It doesn't help a player much to know the chances of being dealt a straight flush or a full house or even a pair. Yet most of the published tables of poker probabilities are confined to that kind of information.

It does help to know the odds against improving any par­ticular hand. A summary of these odds is given on page 94. Memorize those odds. At the very least they will tell you when the pot is offering you good odds on a speculative play.

In the following pages I give some special phases of poker mathematics.

Blind-Opening Draw Poker

Chance of beating one opponent who has not bet voluntarily (that is, chance of beating the blind raiser when you are the blind opener:)

If you draw 5 cards...................................      9 to 1 against you

If you draw 4 cards to an ace.................... to 1 against you

If you draw 3 cards to an A-K....................     Z to 1 against you

If you draw 2 cards to a flush.....................     8 to 1 against you

If you draw 2 cards to a straight.................     8 to 1 against you

If you draw 2 cards to a straight flush.........     6 to 1 against you

If you draw 3 cards to a low pair (4, 3, 2)....     Even

If you draw 3 cards to a medium pair

(5 to 9)........................................ 11/2 to 1 for you

On any better hand than a medium pair you should raise.

Comment: The pot usually offers 4 to 1. It will be seen that the usual plays stand to lose. However, the figures are compli­cated by the high cards in the hand that may pair—see page 58.

The same principles apply to straight draw poker (page 54) when you are next-to-last man and everyone but the dealer is out.

Every additional opponent reduces the odds in your favor on a particular hand. But every additional opponent has to put his money into the pot, thus increasing the odds you are getting for your own money. All poker calculations come to the same thing, though in varying degree: If you had the high hand to begin with, you figure to win. The more players there are against you, the fewer pots you will win but the more you will win each time you win the pot, and in the long run you still show a profit.

Chances of Improving in the Draw (Draw Poker)

Draws to One Pair

Drawing three cards to one pair—odds against making:

Two pair or better................................... to 1 against

Aces up or better.....................................       6 to 1 against

Three of a kind........................................        8 to 1 against

Full house...............................................     97 to 1 against

Four of a kind..........................................    359 to 1 against

Drawing two cards to one pair and an ace kicker-odds against making:

Two pair or better...................................        3 to 1 against

Aces up or better.....................................       4 to 1 against

Three of a kind........................................      12 to 1 against

Full house................................................    119 to 1 against

Four of a kind.......................................... 1,080 to 1 against

Comment: It will be seen that if the player is sure he must have aces up or better to win, his chance is slightly better by holding the Ace kicker.

Draws to Three of a Kind

Drawing two cards to three of a kind—odds against making:

Full house or better................................. 82/3 to 1 against

Full house   ............................................ 151/2to 1 against

Four of a kind......................................... to 1 against

Drawing one card to three of a kind and any kicker—

odds against making:

Full house or better................................. 103/4to 1 against

Full   house   .......................................... to 1 against

Four of a kind.........................................     46 to 1 against

Comment: Holding a kicker to three of a kind decreases the

chance of improvement and obviously can be advisable only for

deceptive or tactical purposes.

Other Odds

The odds are 38 to 9 or to 1 against filling a fourflush; 39 to 8 or almost 5 to 1 against filling a double-ended straight; 43  to 4 or to  1  against filling an inside or one-ended straight; 43 to 4 or to 1 against filling a full house when drawing to two pair.

With a double-ended straight-flush draw (such as

the odds are 2 to  1  against making a straight or better,

to 1 against making a straight flush, 5 to 1 against making a

flush, to 1 against making a straight.

With a one-ended straight-flush draw (such as or

 8-7-5-4), the odds are 3 to 1 against making a straight or better, 46 to 1 against making a straight flush, 5 to 1 against making a flush, 14 to 1 against making a straight.

Drawing four cards to an ace, the odds are 21/2 to 1 against making a pair of aces or better. (In stud poker the odds are 31/2 to 1 against pairing an ace if no other ace shows.) Drawing two cards to A-K, the odds are 21/2 to 1 against making aces or kings, or better.

It is 23 to 1 against making a flush on a two-card draw and 22 to 1 against making a straight on a two-card draw (both ends open twice, as 10-9-8). It is 11 to 1 against making a straight or better on a two-card straight-flush draw such as 10-9-8.

Lowball

The following odds apply to lowball played with the bug. In each case it is assumed that the bug is not in the hand.

One card to 7-high......................................... 31/2 to 1 against

One card to 6-high......................................... .51/2 to 1 against

One card to 5-high......................................... …..9 to 1 against

Two cards to any three cards under 7,

to make 7-high or better................... 271/2 to 1 against

One card to 8-high......................................... …..2 to 1 against

One card to 9-high......................................... Even

Comment: See page 61. The more players there are in the pot, the more low cards can be assumed to have been dealt originally and the worse the chances are for improvement. The same fact decreases the danger of pairing, but this does not alter the fact that the chances of improvement are lessened.
