Life and death is a fundamental concept in the game of Go, where the status of a distinct ''group'' of ''stones'' is determined as either being "alive", where they may remain on the board indefinitely, or "dead," where the group will be lost as "captured". The basic idea can be summarized by: :''A group must have two eyes (meaning secured internal liberties) to live (meaning to survive through to the end of the game).'' ==Explanation== The concept of ''Life and death'' is a consequence of two basic Go rules. * ''A group of stones with no liberties is captured.'' * ''A stone may not be played on a position where it will be captured directly, unless it directly captures another group.'' Because of these rules, some groups can never be captured (''alive''), while others can't avoid capture (''dead''). The group at a is not alive, but may become alive, so is ''unsettled''. The group at b is ''dead''. The group at c and d is ''alive''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「life and death」の詳細全文を読む スポンサード リンク
