Chessboard
Board games have been known since ancient history, with the oldest records being paintings in mastabas of the First and Third Dynasties of Egypt (3100-2700 BC). The first known version of chess appeared around the 6th century in India and was called Chaturanga, played on a board of the game Ashtapada. This board was monochromatic and divided into eight columns by eight rows, with special marks called "castles" in the first, fourth, fifth, and eighth squares of the "a", "d", "e", and "h" columns, which served a function in Ashtapada, but not in Chaturanga.
Sunjang baduk
Sunjang baduk (Korean: 순장바둑) is a variant of the game go (known as "baduk" in Korean) played in Korea which dates to the 16th century. It became obscure in the 1950s when it was largely replaced by modern go due to Japanese influence. There are around 45 surviving game records of Sunjang baduk, mostly from the 1880s. The oldest known game record was published in the "Chosun Ilbo" newspaper on March 1937, although the game was played much earlier. The game is between No Sa-ch'o and Ch'ae Keuk-mun. Sunjang baduk is played on a 19x19 board with 17 marked points which are used as indicators. The first 16 stones are put in a preset pattern on the marked points and black must make their first move on the Tengen (the center point on the board). Due to the prescribed nature of the opening, games tend to be aggressive which leads to fierce middle game fighting.
