Backgammon Notation
Backgammon notation is a means for recording backgammon games, developed by Paul Magriel in the 1970s. The common way of describing the movement of checkers involves numbering the points around the board from 24 to 1 as depicted in Figure 1. The image shows the board from black's perspective, with the numbers diminishing as her checkers move counterclockwise toward her own home board at the bottom right-hand side. The reverse numbering of the points applies when white is on roll, with the 24-point referred to as the 1-point, and so forth. Dice rolls are shown either as "4-2" or "42", denoting a roll of four on one die and two on the other. Moves are recorded using the notation: :4-2: 8/4 6/4 This denotes a roll of 4-2, and the corresponding checker moves from point 8 to 4 and from 6 to 4. After this move, the board will appear as shown in Figure 2. If a move results in a checker being hit, this is indicated by adding an asterisk to the number denoting the point at which the ...

Backgammon
Backgammon is a two-player board game played with counters and dice on tables boards. It is the most widespread Western member of the large family of tables games, whose ancestors date back nearly 5,000 years to the regions of Mesopotamia and Persia. The earliest record of backgammon itself dates to 17th-century England, being descended from the 16th-century Irish (game), game of Irish.Forgeng, Johnson and Cram (2003), p. 269. Backgammon is a two-player game of contrary movement in which each player has fifteen piece (tables game), pieces, known traditionally as 'men' (short for 'tablemen') but increasingly known as 'checkers' in the US in recent decades. These pieces move along twenty-four 'point (tables game), points' according to the roll of two dice. The objective of the game is to move the fifteen pieces around the board and be first to ''bear off'', i.e., remove them from the board. The achievement of this while the opponent is still a long way behind results in a triple wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paul Magriel
Paul David Magriel Jr. (pronounced Ma-grill) (July 1, 1946 – March 5, 2018) was an American professional backgammon player, poker player, and author based in Las Vegas, Nevada. Magriel became New York State Junior Chess Champion (January 1967) at the age of 20, while a student at New York University. Backgammon Known as X-22 on the backgammon circuit, Magriel arguably won more major backgammon tournaments than any other player in the world. He was widely considered the world's premier backgammon teacher, an original and clear-thinking theorist and one of its best players. The sobriquet X-22 originates from Magriel's simulation of a real backgammon tournament (compare simultaneous exhibition in chess) with 64 boards, designated X-1 through X-64, in which the player designated "X-22" has eventually won. Magriel first came to prominence on the backgammon circuit when he won the World Backgammon Championship in 1978. From 1977 to 1980, he wrote weekly backgammon columns for ' ...

Asterisk
The asterisk ( ), from Late Latin , from Ancient Greek , ''asteriskos'', "little star", is a typographical symbol. It is so called because it resembles a conventional image of a heraldic star. Computer scientists and mathematicians often vocalize it as star (as, for example, in ''the A* search algorithm'' or ''C*-algebra''). In English, an asterisk is usually five- or six-pointed in sans-serif typefaces, six-pointed in serif typefaces, and six- or eight-pointed when handwritten. Its most common use is to call out a footnote. It is also often used to censor offensive words. In computer science, the asterisk is commonly used as a wildcard character, or to denote pointers, repetition, or multiplication. History The asterisk has already been used as a symbol in ice age cave paintings. There is also a two thousand-year-old character used by Aristarchus of Samothrace called the , , which he used when proofreading Homeric poetry to mark lines that were duplicated. Origen is know ...
