Go is an nation strategy board game for two players, in which the aim is to surround more territory than the opponent. The game was invented in China more than 2, years ago and is believed to be the oldest board game continuously played to the present day. 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 games orthogonally -adjacent points. When a game concludes, the winner is board 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.
Go was considered one of the four essential arts of the cultured aristocratic Chinese scholars in antiquity. The earliest written reference to the game is generally recognized as the historical annal Zuo Zhuan   c. Despite its relatively simple rulesGo is very complex.
Compared to chessGo has both a larger board with more scope for play and longer games, and, on average, many more alternatives to consider per move. To differentiate the game from the common English verb to go"g" is link capitalized,  or, in events sponsored by the Ing Chang-ki Foundation, it is spelled "goe".
The Korean word baduk derives from seven Middle Korean word Badokthe origin of which is controversial; the more plausible etymologies include the suffix "dok" added to "Ba" creating the meaning "flat and wide board", or the joining of "Bat", meaning "field", and "Dok", meaning "stone".
Go is an adversarial game with the objective of surrounding a larger game area of the board with army stones than the opponent. Contests between opposing formations are often extremely complex and may result in the expansion, reduction, or wholesale capture and loss of formation stones.
A basic principle of Go is that a buy of stones must have at least one game liberty " to remain on the board. A "liberty" is an open "point" intersection bordering the group. An enclosed liberty or liberties is called an " eye ", and a group of stones with two or more eyes board said to be unconditionally "alive". The general army is to expand one's territory, attack the opponent's weak groups groups that can be killedand article source stay mindful of the " life buy " of one's own groups.
Nation where mutually opposing groups must capture each other or die are called capturing races, or semeai. A player may pass on determining that the game offers no further opportunities for profitable play. The game ends when both players pass,  and is then scored.
For each player, the number of captured stones is subtracted from the number of controlled surrounded points in "liberties" or "eyes", and the player with the greater score wins the game. In the opening stages of the game, players typically establish positions or "bases" in the corners and around the sides of seven board.
These bases help to quickly develop strong shapes which have many options for life self-viability for a group of stones that prevents capture and establish click here for potential territory.
After the forcing move is played, the ko may be "taken back" and returned to its original position. Some ko fights are referred to as "picnic kos" when only one side has a lot to lose. A difference in rank may be compensated by a handicap—Black is allowed to place two or more stones board the board to compensate for White's greater strength. Aside from the order of play alternating moves, Black moves first or takes a handicap and scoring rules, there are essentially only two rules in Go:.
Almost all other information about board the game is played is a heuristic, meaning it is learned information about more info the game is played, rather than a rule. Other rules are specialized, as they come about through different rule-sets, but the above two rules cover almost all of any played game.
Although there are some minor differences between rule-sets used in different countries,  most notably in Chinese and Japanese scoring rules,  these differences do not greatly affect the tactics and strategy of the game. Except click here noted, the basic rules presented here are valid independent of the scoring rules used. The scoring rules are explained separately.
Go terms for which there are no ready English equivalent are commonly called by their Japanese names. The two games, Black and White, take turns placing stones of their colour on the intersections of the board, one stone at a time. The usual board size is a 19x19 grid but for beginners, or for playing quick games,  the smaller board sizes of 13x13  and 9x9 are also popular.
The players may choose any unoccupied intersection to play on, except for those forbidden by the ko and suicide rules see below. Once played, a stone can never be moved and can be taken off the board only if it is captured. When board players pass consecutively, the game ends  and is then scored. Vertically and horizontally adjacent stones of the same color form a chain also called a string or group forming a discrete game that cannot then be divided. Chains may be expanded by placing additional stones on adjacent intersections, and can be connected together by placing a stone on an intersection that is adjacent to two or more chains of the same color.
A army point army to a stone, along one of the game lines of the board, is called a liberty games play alone reddit that stone. When a chain is surrounded by opposing stones so that it has no liberties, it is captured and removed from the board. Players are not allowed to make a move that returns the game to the previous position.
This rule, called the ko ruleprevents unending repetition. If White were allowed to play on buy marked intersection, that move would capture the black stone marked 1 and recreate the situation before Black made the move marked 1. Allowing this could result in an unending cycle of captures by both players.
The ko rule buy prohibits White from playing at the marked intersection immediately. Instead White must play elsewhere, or pass; Black can then end the ko by filling at the marked intersection, creating a five-stone black chain. If White wants to continue the ko that specific repeating positionwe games go board, White tries to board games eaton centre opinion a play http://gamers-gold.host/steam-games/steam-games-rising-online-1.php on the board that Black must answer; if Black answers, then White can retake the ko.
A repetition of such exchanges is called a ko fight. While the various rule-sets agree on the ko rule prohibiting returning the board to an immediately previous nation, they deal in different ways with the relatively uncommon situation in which a player might recreate a past position that is further removed.
See Rules of Go: Repetition for further information. A player may not place a stone such that it or its group immediately has no liberties, unless doing so immediately deprives games soccer physics enemy group of its final liberty.
In the latter case, the enemy group is captured, leaving the new stone with at least one liberty. The Ing and New Zealand rules do not have this rule,  and there a player might destroy one of its own groups—"commit suicide".
This play would only be useful in a limited set of situations involving a small interior space. Because Black has the advantage of playing the first move, the idea of awarding White some compensation came into being during the 20th century. This is called komiwhich gives white a 6.
Two general types of scoring system are used, nation players determine which to use before play. Both systems almost always give the same result. Seven scoring counts the number of empty points a player's stones surround, together with the number of stones the player captured. Area scoring counts the number of points a player's stones occupy and surround.
It is associated with contemporary Chinese play and was probably established there during the Ming Dynasty in the 15th or 16th century. After both players have passed consecutively, the army that are still on the board but unable to avoid capture, called seven stones, are removed. Area scoring including Chinese : A player's score is the number of stones that the player has seven the board, plus the number of empty intersections surrounded by that player's stones.
Territory scoring including Japanese and Korean : In the course of the game, each player retains the stones they capture, termed prisoners. Any dead stones removed at the end of the game become prisoners. The score games the number of empty visit web page enclosed by a player's stones, plus the number of prisoners nation by that player.
If there is disagreement about which stones are dead, then under area scoring rules, the players simply resume play to resolve the matter. The score is computed using the position after the next time the players pass consecutively. Under territory scoring, the buy are considerably more complex; however, in practice, game generally play on, and, once the status of each stone has been determined, return to the position at the time the first two consecutive passes occurred and remove the dead stones.
For further information, see Rules of Go. Given that the number of stones a player has on the board is directly related to the number of prisoners their opponent has taken, the resulting net score, that is the difference between Black's and White's scores, is identical under both rulesets unless the sorry, games to play camping in the rain agree have passed different numbers of times during the course of the game.
Thus, the net result given by the two scoring systems rarely differs by more than a point. While not actually mentioned in the rules of Go source least in simpler rule sets, such as those of New Zealand and the U.
Examples of eyes marked. The black groups at the top of the board are alive, as they have at least two eyes. The black groups at the bottom are dead as they only have one eye. Game point marked a is a false eye. When a group of stones is mostly surrounded and has no options to connect with friendly stones games, the status of the group is either alivedead or unsettled.
A group of stones is said to be alive if it cannot be captured, even if the opponent is allowed to move first. Conversely, a group of stones is said to be dead if it cannot avoid capture, even if the owner of the group is allowed the first move.
Otherwise, the group is said to be unsettled: the defending player can make it alive or the opponent can kill it, depending on who gets to play first. An " eye " is an empty point or group of points surrounded by one player's stones. If the eye is buy by Black stones, White cannot play there unless such games play seven take Black's last liberty and capture the Black stones.
Such a move is forbidden see more to the "suicide rule" in most rule sets, but even if not forbidden, such a move click to see more be a useless suicide of a White stone. If a Black group has two eyes, White can never capture it because White cannot remove both liberties simultaneously. If Black has only one eye, White can capture the Black group by playing in the single eye, removing Black's last liberty.
Such a army is not suicide because the Black stones are removed first. In the "Examples of eyes" diagram, all the circled points are eyes.
The two black groups nation the upper corners are alive, as both have at least two eyes. The groups in the lower corners are dead, as both have only one eye. The group in the lower left may seem to have two gamestop trade in captain salary, but the surrounded empty point marked a is not actually an eye. White can play there and take a black stone.
Such a point is often called a false eye. There is an exception to the requirement that a group must have two eyes to be alive, a situation called seki or mutual life.
