This report introduces some new combinations of cards for comparing Poker hands.
In most poker play, and in many other card games, the ranks of the cards are:
table one | ||
---|---|---|
Rank | Symbol | |
highest | Ace | A |
King | K | |
Queen | Q | |
Jack | J | |
Ten | T | |
Nine | 9 | |
Eight | 8 | |
Seven | 7 | |
Six | 6 | |
Five | 5 | |
Four | 4 | |
Three | 3 | |
lowest | Two | 2 |
A common practice is to allow the Ace to be either high (above the King) or low (below the Two) at the player's discrection, but for simplicity we assume that the Ace will always be high.
Here are two new terms for old ideas:
The gist of the system proposed here is not complicated. To determine who has the best hand in a Poker showdown, players compare their cards according to the two-step rule:
To illustrate, a player who holds Q-J-T-T-9 would regard the melds as QJT9 and T, not QJT and T9.
Examples are given in table two below. The greater-than symbol > stands for "defeats", and the small x stands for any irrelevant card. The hyphen is inserted for convenience of reading, separating sequences within the hand.

Note for instance that 432-76 defeats AKQ-A-A because any v32 defeats any v311. The question of which hand has cards of higher ranks arises only when two hands of the same category are compared, and the category is established in step one of the two-step rule.
Within the hand, one sequence will sometimes be contained within another (as QJT-JT or 54-54-9) or not contained (as QJT-43 or KQ-54-9). However, this makes no difference in the ranking of hands as proposed here. Of course, some players might choose to give contained sequences special treatment.
Although we do not treat horizontal and flush melds extensively, it is still worthwhile to establish notations.

Flushes are based on matching suit, not rank. In most Poker play, no suit is regarded as superior to any other, and traditionally the only flush meld recognized is the f5. In the flush generalizations of table four, the suits are spades (♠), clubs (♣), hearts (♥), and diamonds (♦). Although many European packs use other suit symbols, nearly all have four suits.

By long tradition, a Poker hand has five cards. Although five-suit packs of cards have been published, they have for unclear reasons rarely been adopted by Poker players, even though a meld with five cards of the same rank would be possible, as well as a hand with five different suits.
Returning to vertical melds, table six tells how many hands fall into each of the seven categories; displayed are both a count and a percentage. Although the 13-rank pack is the most common in the United States and Britain, packs of 12 or 10 ranks are common in southern Europe, and 8 ranks in central Europe. For 14 ranks, players can use a Rook pack or the minor arcana from a Tarot pack; and to obtain 15 ranks, players can use 60 cards from a six-handed 500 pack.
In general, reducing the number of ranks leads to an increase in the occurence of longer sequences. Reducing the number of suits, while perfectly feasible, is almost never done. See also stripped deck.

Such a table does not tell the whole story in Draw Poker, because players can discard unsatisfactory cards and draw replacements that are potentially better. Under the ranking of the vertical melds as given above, a player has very little to lose by discarding a "leftover" card, in other words any card that forms a sequence whose length is only one. For example, with the category v311 hand 765-9-3, the 9 and 3 may be discarded with minimal risk, as their replacements cannot cannot drop the hand into v221 or any lower category. There is a small chance that, after the draw, the hand may turn out to be slightly weaker in an extended tiebreaker, as when 987-5-3 deteriorates to 987-4-2.
Table seven shows the probabilities with a pack of 13 ranks, and varying numbers of cards per rank. The percentages do not change much.

Poker can also be played with a 48-card Pinochle pack, with only six ranks (A, K, Q, J, T, 9) but eight cards in each rank. Further, the nines can be removed from the pack for a tauter game. The prevalence of longer sequences is greatly increased, as enumerated in table eight.

It would extremely cumbersome if players found it necessary to calculate the probabilities and remember which hands defeat which others for each of the many possible configurations. This is especially true if variants beyond those listed here are introduced; and Poker players frequently experiment with rule alterations. The two-step rule, applied under all circumstances, makes the game far more tractable.
Table nine shows the distribution of hands when other than five cards are dealt.

These vertical meld combinations can be used in almost any kind of Poker playing; some genres are listed below.
Players often speak of cards that are "face up" or "face down". The former applies to public cards that are literally lying face up on the table for all players to see. The latter refers to private cards that either are lying face down on the table, with the owner lifting a corner to peek; or are not touching the table at all but are instead held in the owner's hand so that only he can see them.
Straight Poker. Here, "straight" means "plain", and it does not refer to a sequence of cards. This is the simplest, and possibly original, Poker. Cards are dealt face down to the players, there is one betting interval, and then hands are shown.
Draw Poker. A representative format is this:
Stud Poker. A popular choice among the many versions has each player being dealt seven cards, selecting the five that will give him the best standard Poker hand, and ignoring the other two. However, with the vertical meld system of this report all seven cards can participate. In typical practice:
Community Card Poker. In this vast family of games, a few cards are dealt (usually face down) to each player, and a few cards are dealt (either face up or down) to the center of the table — these are the community cards. There are multiple betting intervals, and any face-down commmunity cards are turned up as the game progresses. At the end, each player forms the best five-card hand choosing from his own cards and the community cards. As with Stud, the vertical meld system allows all cards to figure into the final result, instead of just five.
"Mexican" Stud Poker. This follows the general principles of Stud, but all cards are dealt face down, and from time to time each player performs a rollover, turning one of his face-down cards face up. Of course, for rolling over a player tries to select whichever card will most confound his opponents, and this introduces great latitude for strategy. Rollovers can also be employed in Draw Poker.
With the vertical meld system, a player is often able to roll over several cards without giving his opponents any particular indication of how good his hand really is. The following is an example where each player was dealt seven cards, and at a later stage of the game has rolled over four of them. Suppose his face-up cards are Q-T-8-6, with three of his cards still face down. Then as far as his opponents can tell, he might hold almost any of the 15 seven-card categories of table nine, including the extremes v7 (QJT9876) and v1111111 (A-Q-Q-Q-T-8-6).
The two-step rule means that two Poker hands can be compared even if they have different numbers of cards: as always, whoever has the longest sequence wins.
Here is an illustration of how that works. Suppose in a modification of Draw Poker each player is dealt nine cards; and when drawing must discard two cards, receiving only one in return. After several rounds of betting and drawing, a player who has drawn four times now has five cards (v41 = 9876-2), while another who drew two times now has seven (v322 = KQJ-76-32). The player with the v41 wins because he has the longest sequence, even though his opponent has more cards.
When breaking ties under step one of the two-step rule, a player loses if he runs out of sequences before his opponent. For instance, 7654-2 defeats KQJT.
