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.

Poker Paigow

Paigow

Pai-gow poker is a banking poker game played in some of the California card clubs and casinos. The object of pai-gow poker is to make two poker hands that beat the banker's hands. The player is dealt 7 cards that he makes into a five card hand (high hand) and a two card hand (low hand). The hands are played and ranked as traditional poker hands (with one exception: A2345 is the second highest straight), and the 5 card hand must be higher than the 2 card hand. If both hands are better than the banker's hand, you win, if both lose, you lose, otherwise it's a push. The banker wins absolute ties (i.e. K Q vs K Q). The game is played with a 52 cards plus one joker. The joker can be used as an Ace or to complete a flush or straight.

Each player spot has spaces for a bet, low hand, high hand and sometimes the house commission. The dealer deals 7 7-card hands in front of the chip tray. The banker can be a player, but is usually the house. The banker designates which hands go to which player by shaking a dice cup with three dice; the banker's position is either 1, 8 or 15 and the hands are passed out counterclockwise. So, if the dealer is the bank and the dice total to 6, player 5 gets the first hand, player 6 gets the second, the dealer gets the third and so on. The dice mumbo-jumbo appears to be ritual stuff --- you don't need to worry about anything until you get your hand.

In pai-gow poker, the only strategic decisions are how much to bet and how to set your hand. The simple basic strategy for setting your hand is to make the highest 2-card hand that is less than your five card hand. If you can't figure out what to do, you can show your hand to the dealer and they will tell you how the house would set it.

In the California card clubs, all wagering is between players, so the option to be the bank rotates among the active players. The rule differences from the IP rules are that the Joker is wild, and the house commission is a flat $1 per hand ($10 minimum bet).

Pai-gow poker is an easy game to play, and since each hand takes a while to play (dealer has to shuffle for each game) and most hands push, you can play on $20 at a $5 table for quite a while.
