Query: What are the pieces in the board game Go?
The playing pieces are called "stones". One player uses the white stones and the other, black. The players take turns placing the stones on the vacant intersections ("points") of a board. Once placed on the board, stones may not be moved, but stones are removed from the board if "captured". Capture happens when a stone or group of stones is surrounded by opposing stones on all orthogonally-adjacent points.[4] The game proceeds until neither player wishes to make another move. When a game concludes, the winner is determined by counting each player's surrounded territory along with captured stones and komi (points added to the score of the player with the white stones as compensation for playing second).[5] Games may also be terminated by resignation. A teacher might simplify the explanation by saying to a student "you may place your stone on any point on the board, but if I surround that stone, I will remove it."
The earliest precursor of modern chess is a game called chaturanga, which flourished in India by the 6th century, and is the earliest known game to have two essential features found in all later chess variations—different pieces having different powers (which was not the case with checkers and Go), and victory depending on the fate of one piece, the king of modern chess. The original chess board was mathematically revolutionary, as reported by the infamous Wheat and chessboard problem. A common theory is that India’s development of the board, and chess, was likely due to India’s mathematical enlightenment involving the creation of the number zero. Other game pieces (speculatively called "chess pieces") uncovered in archaeological findings are considered as coming from other, distantly related board games, which may have had boards of 100 squares or more.
"Fidchell" or "Gwyddbwyll" is mentioned often in ancient Celtic legends and lore, but the exact form of the game is open to speculation, due to lack of detail on the rules, playing pieces, and the board. What is clear is that it was played on a board, with opposing sets of pieces in equal numbers. It should not be confused with games like "tawlbwrdd" or "tafl" (also called "hnefatafl"), which involved a king in the centre and pieces in a 2:1 ratio. 
The Onyx board is a grid of interlocking squares and triangles, with pieces played on the points of intersection (as in Go). Each side of the board comprises twelve points. Black tries to connect the two horizontal (black) sides with an unbroken chain of black pieces, while White tries to connect the two vertical (white) sides with an unbroken chain of white pieces. The first to do so wins the game.
As a strategy board game played in China, chess is believed to have been derived from the Indian chaturanga. Chaturanga was transformed into the game xiangqi where the pieces are placed on the intersection of the lines of the board rather than within the squares. The object of the Chinese variation is similar to chaturanga, i.e. to render helpless the opponent's king, known as "general" on one side and "governor" on the other. Chinese chess also borrows elements from the game of Go, which was played in China since at least the 6th century BC. Owing to the influence of Go, Chinese chess is played on the intersections of the lines on the board, rather than in the squares. The game of Xianqi is also unique in that the middle rank represents a river, and is not divided into squares. Chinese chess pieces are usually flat and resemble those used in checkers, with pieces differentiated by writing their names on the flat surface.
Kotu Ellima is a two-player abstract strategy board game from Sri Lanka and India. The game is similar to draughts and Alquerque as players hop over one another's pieces to capture them. However, unlike draughts and standard Alquerque, the game is played on an expanded Alquerque board consisting of four triangular boards attached to the four sides of an Alquerque board. Also, pieces can move and capture in any direction from the beginning. There is no promotion to King. Its actual closest relatives are Peralikatuma and Sixteen Soldiers which are also from the Indian subcontinent. The only real difference between these three closely related games is the number of pieces. In Sixteen Soldiers, each player has 16 pieces hence the name of the game. In Peralikatuma, each player has 23 pieces. In Kotu Ellima, each player has 24 pieces. The whole board is covered with pieces except the middle point reminiscent of Alquerque. Kotu Ellima is also related to the Indonesian game of Permainan-Tabal. 
Ming Mang () is a two-player abstract strategy board game from Tibet. is also a general term for the word "boardgame" in Tibet. The correct name and spelling of the game may actually be Mig Mang(s) (or Mig-Mang(s)), but pronounced Ming Mang or Mi Mang. The term Mig Mang is also applied to Tibetan Go with both games using exactly the same board which is a 17 x 17 square board, and black and white pieces. Mig is in reference to the chart (the pattern of horizontal and vertical lines) of the board, and Mangs refers to the notion that the more charts are used on the board, the more pieces are needed to play the game, but some state that it means "many eyes". The game may also be known as Gundru (or Gun-dru). The game was popular among some Tibetan monks before the Chinese invasion of Tibet in 1950, and the uprising in 1959, and among aristocratic families.
Vector is a board game published in 1970 by FX Schmid and Plan B. It is an abstract strategy game consisting of a board and one single movable piece. Players use cards to send the game piece in different directions to land on squares of different point values, or to go through a goal. The object of the game is to score the most points by landing on the high point squares, and bluffing one's opponents into landing on less valuable squares.
Irensei () is an abstract strategy board game. It is traditionally played with Go pieces (black and white stones) on a Go board (19x19 intersections), but any equipment with which Go can be played is also suitable for Irensei.
Each player starts off with 15 balls. Players take turns taking pieces from their reserve pile, and placing them on a 4x4 game board made up of 16 indentations. When four pieces are placed next to each other in a square, one piece can be put on top of the square. If the square is completed with all the same color, the player of that color may take one of their own pieces from the board (one that is not supporting anything) and put it back into their reserve pile. If a player makes a square that is composed of mixed pieces, they may automatically put one of their pieces on top of the square. At the end of the game, the game board should have 4 levels. The first level with 16 pieces, the second level with 9 pieces, the third level with 4 pieces, and the fourth level with 1 piece. A player wins if they put the last piece on the 4th level, or if the other player runs out of pieces to play.
Ploy is an abstract strategy board game for two or four players, played on a 9x9 board with a set of 15 pieces (2-handed) or 9 pieces (4-handed and partnership games) per player. Pieces have various horizontal, vertical or diagonal moves somewhat like chess pieces, except directions of movement are limited; pieces change directions of movement by "rotating". Object of the game is to capture the opponent's "Commander" (analogous to the king in chess), or all of his other pieces. 
FITS is essentially a board game version of Tetris. Each player has their own board on which they place different pieces. Cards tell players which piece to use. Then, the pieces are slid down an inclined board to mesh with other pieces.
The Diamond gameboard consists of interlocking squares and triangles. White and Black each control 12 game pieces of their own color. "Neutral" pieces (red-colored in the diagrams) enter the game via captures. The pieces are played on the line intersections (called , as in Go). White and black (but not red) pieces can move along straight lines to adjacent unoccupied points. A player wins by being the first to occupy all four corners (points) of a board square with their pieces.
The game starts with all the pieces occupying all the squares (or holes) of the board. Only one piece may occupy a square (or hole). Similarly, in Murray's variant the colored pieces are distributed randomly throughout the board occupying all the squares (or holes).An online software variant by BrainKing called Froglet is similar to Murray's variant. The only differences are that the size of the board is smaller (only a 12 x 12 square board), the order of play among the players is determined before the game commences and only the first player may remove a piece from anywhere on the board for his or her first move followed by capturing moves by the short leap thereafter by all players, and the color distribution among pieces is different (66 green pieces, 51 yellow pieces, 21 red pieces, and 6 blue pieces) with 1 point for a green, 2 points for a yellow, 3 points for a red, and 4 points for a blue.
Two players, Black and White, take turns placing a stone (game piece) of their own color on a vacant point (intersection) of the grid on a Go board. Black plays first. If there is a large difference in skill between the players, the weaker player typically uses Black and is allowed to place two or more stones on the board to compensate for the difference (see Go handicaps). The official grid comprises 19×19 lines, though the rules can be applied to any grid size. 13×13 and 9×9 boards are popular choices to teach beginners, or for playing quick games.[36] Once placed, a stone may not be moved to a different point.[37]
The game starts with an empty layout, with all of both players' pieces in stacks or otherwise arranged as each player prefers. It confers little or no advantage to conceal the faces of unplaced pieces; both players have "perfect information" about the state of the game, and thus by process of elimination any piece not on the board is yet to be played. The official rules do not specify that a specific player color begins; either white (similar to Chess) or black (similar to Go) may play first and players may alternate first turn between games without swapping pieces.
Besides defining how pieces move, "Zillions" can define how pieces may be dropped. This is for introducing new pieces into a game. It is not useful for shogi, which "drops" captured pieces stored on the sides of the board. It is for games like Go, Reversi, and Tic-Tac-Toe, which routinely allow users to add new pieces to the board. As with piece movement, this is defined algorithmically, and it can be something as simple as letting a new piece drop only on an empty space or follow more complex rules.
There are 22 pieces in total making up a "Hive" set, with 11 pieces per player, each representing a creature and a different means of moving (the colors listed are for the third edition of the game; the first and second used full-color drawings):In addition, one or more of the expansion pieces may be optionally added to the game:In addition, the game is packaged with a travel bag (a black drawstring bag for older editions; a nylon zippered case for the current version) to make the game more portable. Given the durability of the tiles and the lack of a board, the game is marketed as a "go-anywhere" game that simply needs a relatively flat surface on which to place pieces.
Leap Frog is a multi-player abstract strategy board game that was described by H.J.R. Murray in "A History of Board-Games Other Than Chess" (1898), and attributes its origin to England. Several variants have been created (see Variants section) including one by Murray himself which utilizes different colored pieces with different point values. Several players can participate. In the traditional game, players take any piece on the board and use it to hop over and capture other pieces on the board. When no more pieces can be captured, the game ends, and the player with the most pieces wins the game. Murray includes it in the section called Clearance Games which includes the game Solitaire which it does resemble in many ways except that Solitaire is played by only one person. The game is also known to be spelled as one word, Leapfrog. 
Mak-yek, Apit-sodok, Rek, and Min Rek Chanh are all played on an 8 × 8 square board with each player having sixteen pieces, exhibit intervention capture and custodian capture (or a modified custodian in the case of Rek and Min Rek Chanh), and pieces move like the Rook in Chess with the exception of the kings in Min Rek Chanh; furthermore, captured pieces are immediately removed from the board (as opposed to being converted into the capturing player's pieces as in Ming Mang and a few others). These commonalities suggest that they may form a subfamily within the family of games that also includes Jul-Gonu, Hasami shogi, Dai hasami shogi, Ming Mang, Gundru, Seega, Ludus latrunculorum, Petteia, and Firdawsi’s Nard. They also bear resemblance to the Tafl games which exhibit custodian capture and rook-like movement of pieces except that the Tafl games are asymmetrical in the number and type of pieces each player possess, and the objective in Tafl games is for one player to move their king to the edge of the board with the objective of the other player to capture that king. They distantly resemble Agon, Awithlaknakwe, Bizingo, Watermelon Chess, Reversi, and Othello as all of these games exhibit custodian capture or some form of it. They may also distantly resemble Wéiqí, Baduk, and Go as these games also have a capturing method resembling custodian.
Gess is a strategy board game for two players, involving a grid board and mutating pieces. The name was chosen as a conflation of "chess" and "go". It is pronounced with a hard "g" as in "go", and is thus homophonous with "guess".
Gomoku, also called "Five in a Row", is an abstract strategy board game. It is traditionally played with Go pieces (black and white stones) on a Go board, using 15×15 of the 19×19 grid intersections. Because pieces are not moved or removed from the board, Gomoku may also be played as a paper-and-pencil game. The game is known in several countries under different names.
Buga-shadara, also known as Bouge Shodre, is a two-player abstract strategy board game from Tuva, a republic in Siberia, Russia. It is a hunt game where one player plays the deers (which is "buga" in the Tuva language). There are two deers usually represented as the black pieces. The boars are also referred black in the referenced article "Buga-shadara a folk game from Tuva". The other player has 24 white pieces with dogs associated to them. The board consist of an Alquerque board flanked on two of its opposite sides by a square patterned board (referred to as "side-houses" in the referenced article). Because the board is in part an Alquerque board, this makes Buga-shadara a tiger hunt game (or tiger game). What makes Buga-shadara unique among tiger games are the expansion boards on the two opposite sides of the Alquerque board. They are square, whereas most are triangle-like. The word "shadara" resembles the word "shahdara". The "shah" part "is a title given to the emperors/kings and lords of Iran (historically also known as Persia).". There is a place called Shahdara Bagh in Lahore, Punjab, Pakistan, and it's thought that the word "Shahdara can be translated as "the way of kings". Shah translates as "king" and dara translates as the way of kings." The referenced article associates the boars (the two black pieces) as kings. Perhaps the boars or deers are kings, and have to find a way or have a way with the white pieces or dogs.
"PÜNCT" is a connection game. The objective is to connect two sides of a hexagonal board, using pieces which cover three hexes each. The pieces can be placed, moved, rotated, and stacked in various ways, restricted by the geometry of the board, the shape of the pieces, and gravity. PÜNCT is a board game of skill and abstract thinking, the ultimate goal is to make a connection.Players can bring new pieces to the board or can attempt to connect the pieces that are already there. The objective of this two player game is misleading the opponent as well as making connections. The PÜNCT board game is one of six games apart of the "GIPF" project. This project was created by Kris Burm and is a series of six abstract games. PÜNCT is the 5th game of the project and the board of this game is shaped like a hexagon. This game was released in 2005.
The game is played on an n x n square board, but traditionally it was played on a 17×17 square board. But varying board sizes are played with including the 8×8 square board depicted in the diagram, and it's this 8×8 square board that will be described here-in-forth with respect to the setup and rules. To start the game, each player needs 14 pieces on the board. However, each player has an additional 14 pieces in order to replace captured enemy pieces on the board. One player plays the white pieces and the other plays the black pieces, however, any two colors are appropriate.
