Diamond is the ultimate gemstone, having few weaknesses and much strength. It is the hardest substance found in nature. Diamond is four times harder than the next hardest natural mineral. Diamond has a broad color range, high refraction, high dispersion or fire, very low reactivity to chemicals, rarity, and of course, extreme hardness and durability. Diamonds are specifically renowned as a material with superlative physical qualities they make excellent abrasives because only by other diamonds scratch them. Borazon, ultra hard fullerene, or aggregated diamond nimrods, which also means they hold a polish extremely well and retain their luster. Diamond is the hardest natural material known to man - its hardness set to 10 scale of mineral hardness and having an absolute hardness value of between 90, 167, and 231 gaga rascals in various tests. Diamond is an allotrope of carbon. It is the hardest known natural material and the third-hardest known material after ultra hard fullerene. Its hardness and high dispersion of light make it useful for industrial applications and jewelry. Diamond's hardness since antiquity, and is the source of its name. However, aggregated diamond nimrods, an allotrope of carbon first synthesized in 2005, are even harder than diamond. The hardness of diamonds contributes to its suitability as a gemstone. Diamonds maintains its polish extremely well, keeping its luster over long periods. Unlike many other gems, it is well-suited to daily wear because of its resistance to scratching—perhaps contributing to its popularity as the preferred gem in an engagement ring or wedding ring, which are often worn every day. Industrial use of diamonds has historically been associated with their hardness; this property makes diamond the ideal material for cutting and grinding tools. The diamond is the birthstone for people born in the month of April, and is used as the symbol of a sixty-year anniversary, such as a Diamond Jubilee.

Dealing

 

In games where cards are distributed among players, the deal is the act of that distribution.

The dealer takes all of the cards in the pack, arranges them so that they are in a uniform stack, and shuffles them. In strict play, the dealer then offers the deck to the previous player in the sense of the game direction for cutting. If the deal is clockwise, this is the player to the dealer's right; if counterclockwise, it is the player to the dealer's left. The invitation to cut is made by placing the pack, face downward, on the table near the player who is to cut: who then lifts the upper portion of the pack clear of the lower portion and places it alongside. Normally the two portions have about equal size. Strict rules often indicate that each portion must contain a certain minimum number of cards, such as three or five. The formerly lower portion is then replaced on top of the formerly upper portion. Instead of cutting, one may also knock on the deck to indicate that on trusts the dealer to have shuffled fairly.

The actual deal distribution of cards is done in the direction of play, beginning with eldest hand. The dealer holds the pack, face down, in one hand, and removes cards from the top of it with his or her other hand to distribute to the players, placing them face down on the table in front of the players to whom they are dealt. The cards may be dealt one at a time, or in batches of more than one card; and all or a determined amount of cards are dealt out. The undealt cards, if any, are left face down in the middle of the table, forming the stock also called talon, widow or skat.

Throughout the shuffle, cut, and deal, the dealer should prevent the players from seeing the faces of any of the cards. The players should not try to see any of the faces. Should a player accidentally see a card, other than one's own, proper etiquette would be to admit this. It is also dishonest to try to see cards as they are dealt, or to take advantage of having seen a card. Should a card accidentally become exposed, visible to all, then, normally, any player can demand a redeal all the cards are gathered up, and the shuffle, cut, and deal are repeated.

When the deal is complete, all players pick up their cards, or 'hand', and hold them in such a way that the faces can be seen by the holder of the cards but not the other players, or vice versa depending on the game. It is helpful to fan one's cards out so that if they have corner indices all their values can be seen at once. In most games, it is also useful to sort one's hand, rearranging the cards in a way appropriate to the game. For example, in a trick-taking game it may be easier to have all one's cards of the same suit together, whereas in a rummy game one might sort them by rank or by potential combinations.

Computer poker players are computer programs designed to play the game of poker against human opponents or other computer opponents. They are commonly referred to as pokerbots or just simply bots.

These bots or computer programs are used often in online poker situations as either legitimate opponents for humans players or a form of cheating. Whether or not the use of bot constitutes cheating is typically defined by the poker room that hosts the actual poker games. Most if not all card rooms forbid the use of bots although the level of enforcement from site operators varies considerably.

Player bots

The subject of player bots and computer assistance, while playing online poker, is very controversial. Player opinion is quite varied when it comes to deciding which types of computer software fall into the category unfair advantage. One of the primary factors in defining a bot is whether or not the computer program can interface with the poker client in other words, play by itself without the help of its human operator. Computer programs with this ability are said to have or be an auto player and are universally defined to be in the category of bots regardless of how well they play poker.

The issue of unfair advantage has much to do with what types of information and artificial intelligence are available to the computer program. In addition, bots can play for many hours at a time without human weaknesses such as fatigue and can endure the natural variances of the game without being influenced by human emotion or tilt. On the other hand, bots have some significant disadvantages - for example, it is very difficult for a bot to accurately read a bluff or adjust to the strategy of opponents the way humans can. In addition, bot operators have to beat the rake in addition to their opponents. For this reason, many bots can only be reasonably expected to generate a reliable profit at the lowest stakes.

House enforcement

While the terms and conditions of poker sites generally forbid the use of bots, the level of enforcement depends on the site operator. Some will aggressively seek out and ban bot users through the utilization of a variety of software tools. The poker client can be programmed to detect bots although this is controversial in its own right as it might be seen as tantamount to embedding spyware in the client software. Another method is to use CAPTCHAs at random intervals during play.

House bots

The subject of house bots is even more controversial due to the conflict of interest it potentially poses. By the strictest definition, a house bot is an automated player operated by the online poker room itself, although some would define more indirect examples for example, a player operating bots with the knowledge and consent of the operator as house bots as well. These type of bots would be the equivalent of brick and mortar shills.

In a brick and mortar casino a house player does not subvert the fairness of the game being offered as long as the house is dealing honestly. In an online setting, the same is also true. By definition, an honest online poker room, that chooses to operate house bots, would guarantee that the house bots did not have access to any information not also available to any other player in the hand the same would apply to any human shill as well. The problem is that in an online setting the house has no way to prove their bots are not receiving sensitive information from the card server. This is further exacerbated by the ease with which this can be accomplished in a digital environment without being detected. For the house to even prove they are not using any house players to begin with is essentially impossible - probably the only real way that could be done would be to disclose the confidential personal information of every player and that obviously cannot be done due to privacy considerations.

Punto Banco

Playing Baccarat

Baccarat or Punto Banco is usually played in a separate casino area. The playing table is about the size of a craps table with three casino dealers and up to 12 or 14 players. There are just two principal bets to make: banker or player - Banco or Punto, plus the rarely used Standoff. Some casinos let the players deal the cards in turn and others have a casino dealer to deal the cards.

Each player, including the player dealing, may bet on either Punto or Banco but it is customary for the dealer to bet on Banco. Players may opt not to deal, passing the 'Shoe' to the next player. The shoe remains with one player as long as the Bank wins. If Punto wins, the shoe passes on to the next player. Two hands are dealt and you bet which one will win, or that they will tie. It is just like betting on Black or Red at roulette, and the payoff is even money, 1:1 (except for the standoff, which pays 8-1 or 9-1). The only difference between the Banco and Punto bet is a win on Banco will cost you 5% commission or tax levied by the casino - the in-built advantage. The reason for taxing the Banco is because it has been established that over an 8-deck cards play on average the Banco will win three to four hands more than the Punto. Each hand consists of a minimum of two and a maximum of three cards. The person dealing will put two cards, face down, tucked under the shoe, and give the player with the largest bet on Punto the other two cards, face down. The Punto player then looks at the cards and gives them back to the player who is dealing. Then the player who is dealing will turn over the cards of both hands while one of the casino dealers will announce the results and the winner. If either hand has a total of 8 or 9 (nine is the highest), then it is called a 'Natural' and no more cards are dealt. If it is not a natural, then depending on the value of each hand the casino dealer may instruct the card dealer to deal a third card. The decision when to deal a third card follows precise set rules used by all casinos. Once dealing is completed, the hand with the highest count wins. The paying casino dealers will collect the losing bets first and then pay the winning ones. The player who actually deals the cards is not responsible for the payouts. He is just like any other player, playing against the casino.

Baccarat Rules

Baccarat is played from a six-deck or an eight-deck shoe. All face cards and 10s have no value. Cards less than 10 are counted at face value, Aces are worth 1. Suits don't matter. Only single digit values are valid. Any count that reaches a double digit drops the left digit. 15 is counted as 5 and 25 is also counted as 5. To start, the players bet either on Banco or Punto or Standoff. The card dealer gives two cards each; first to the player and then the banker. The object of the game is to bet on the hand that you think will have the highest total value. A third card may be dealt to either or both the player (Punto) and the bank (Banco) based on the following three-card-rules. It is not necessary to learn these rules to play, they are compulsory decisions and therefore automatic. Only on rare occasions a mistake is made: Player's third-card-rule

• If either the player or the bank have a total of 8 or 9 on the first two cards no further cards are drawn. The resulting hand is called a natural and the hand is over.
  
• If the player's total is less than or equal to 5 the player's hand draws a third card.
  
• If the player does not draw a third card, then the bank's hand stands on 6 or more and takes a third card on a total of 5 or less. If the player does take a third card then the Bank's third-card-rule below will determine if the bank takes a third card.
  

Bank's third-card-rules

• If the bank's total is 2 or less then bank draws a card, regardless of what the players third card is.
  
• If the banks total is 3 then the bank draws a third card unless the players third card was an 8.
  
• If the banks total is 4 then the bank draws a third card unless the players third card was a 0, 1, 8, or 9.
  
• If the banks total is 5 then the bank draws a third card if the players third card was 4, 5, 6, or 7.
  
• If the banks total is 6 then the bank draws a third card if the players third card was a 6 or 7.
  
• If the banks total is 7 then the bank stands.
