Point Shaving

In organized sports, point shaving is a type of match fixing where the perpetrators try to prevent a team from covering a published point spread. Unlike other forms of match fixing, sports betting invariably motivates point shaving. A point shaving scheme generally involves a sports gambler and one or more players of the sports team favored to win the game. In exchange for a bribe, the player or players agree to ensure that their team will not cover the point spread. The gambler then wagers against that team.

Basketball

Basketball is a particularly easy medium for shaving points because of the scoring tempo of the game and the ease by which one player can influence key events. By deliberately missing shots or committing well-timed turnovers or fouls, a corrupt player can covertly ensure that his team fails to cover the point spread, without causing them to lose the game or to lose so badly that suspicions are aroused. Although the NCAA has adopted a zero tolerance policy with respect to gambling activity by its players, some critics believe it unwittingly encourages point shaving due to its strict rules regarding amateurism, combined with the large amount of money wagered on its games. The NCAA has produced posters warning of this, the most notable being an athlete sitting alone on a bench with his face buried in his hands although this may also look like the athlete suffered a tremendous defeat with the caption DO NOT BET ON IT with warnings as to what could happen if they are involved in such a plan as well as an athlete being caught gambling himself .

Famous examples of this are the CCNY Point Shaving Scandal of the 1950-51 and the Boston College basketball point shaving scandal of 1978-79, which was perpetrated by gangsters Henry Hill and Jimmy Burke.

Sports Point Shaving

The technique has been used by both amateur and professional athletes in many other sports. The intention is to manipulate scoring so that the final score results in a predetermined outcome. A typical sports game should always tend to behave in a nondeterministic manner. In other words, the exact final score of a game exists in a set, which can contain more than a thousand possible combinations. Furthermore, nondeterminism suggests that the final score of a sports game is practically unpredictable.

Many variables can influence the outcome. Such variables include weather, fatigue, and human error. However, amateur and professional athletes who are very skilled in the technique of point shaving can consistently create unlikely outcomes in bad weather and other challenging conditions. These unlikely outcomes tend to create huge financial gains/losses in prediction markets.

The deviation from the mean, otherwise known as the expected value, is what makes these outcomes so unlikely. In most sports, the expected value is a mathematical prediction that can be expressed as a scoring differential. This scoring differential is also calculated by casinos; and, gamblers generally refer to it as a point spread. In many cases of point shaving, the final outcome deviates substantially from the expected value, or the point spread. Additionally, the deviation from the expected value can be quite large. Many times, the deviation is so large that athletes on opposing teams must cooperate in order to achieve the desired result. In this particular case, the final outcome is commonly referred to as a thrown game.

Playing Cards

 

A playing card is a piece of specially prepared heavy paper, thin cardboard, or thin plastic, figured with distinguishing motifs and used as one of a set for playing card games. Playing cards are typically palm-sized for convenient handling.

A complete set of cards is called a pack or deck, and the subset of cards held at one time by a player during a game is commonly called a hand. A deck of cards may be used for playing a great variety of card games, some of which may also incorporate gambling. Because playing cards are both standardized and commonly available, they are often adapted for other uses, such as magic tricks, cartomancy, or building a house of cards.

The front or face of each card carries markings that distinguish it from the other cards in the deck and determine its use under the rules of the game being played. The back of each card is identical for all cards in any particular deck, and usually of a single color or formalized design. Usually every card will be smooth however some decks have braille to allow blind people to read the card number and suit. The back of playing cards is sometimes used for advertising. For most games, the cards are assembled into a deck, and their order is randomized by shuffling.

Poker Omaha

Omaha

According to Omaha Poker Rules, there are four betting rounds in a complete game - exactly the same as in Texas Holdem Poker. In Omaha Holden, the dealer deals each player their own four private cards face-down.

Each bet on the first two rounds of betting is set at the lower limit of the stakes structure. For example in a $5/$10 game, all bets and raises are $5 for the first two rounds (after private cards are dealt and once the flop is spread in center of table).

The last two rounds of betting (turn card and river) are set at the higher limit of the stakes structure. For example in a $5/$10 game, all bets and raises are $10 for the last two rounds.

One bet plus three raises (four total bets) are the maximum amount of bets allowed per betting round. This would consist of (1) a bet, (2) a raise, (3) a re-raise, and (4) a cap. The term cap is used to describe the 3rd raise in a round since betting is then capped and cannot be raised anymore. Once any player has made the third raise (capped the pot), then players will have only the option of calling or folding.

Check-raising is allowed in all online poker games.

Dealer Button

In order to designate which player is the theoretical dealer in Omaha high low poker games, a round disk is used. This disk is called the dealer button or simply "the button".
After each hand is completed, the button moves clockwise to the next active player and this player will be considered to be the dealer, and will act on their hand last on each betting round. This is also termed playing the button for that game.

Blinds
The player to the left of the button is first to receive a card and is required to post a small blind. The small blind is equal to half the lower limit bet rounded down to the nearest dollar. The player to the left of the small blind is required to post the big blind. The big blind is equal to the lower limit bet. These bets are referred to as blinds because players must post them before the dealer deals any cards to the players. These blinds are similar to the ante that is required in other games such as 7-Card Stud.

Omaha Poker Rules specify that both the small and the big blinds are considered live bets. They have the option of checking, calling, raising or folding when the betting action comes back around to their position. After the flop and after each subsequent betting round, the first active player left of the button is first to act.

When players first sit down to play, they will be required to post the equivalent of the big blind only once or they have the option to "sit out" until it is their natural turn to post the big blind. This rule is in place to ensure game fairness to all players, as it prevents the possibility of players entering games in late position and then leaving before they are required to post the big blind.

HOW TO PLAY
The dealer deals each player their own four private cards face-down.

First betting round

The dealer spreads three community boardcards face-up on the table. This is commonly called "the flop".

Second betting round

The dealer turns over a fourth boardcard face-up commonly called "the turn card".

Third betting round

The dealer turns over one final community boardcard commonly called "the river card".

Final betting round

Players show their hands. This is commonly called "the showdown".

When players show their hands, they MUST use exactly: two of their private cards plus three of the five board cards.
