Question: Both Janggi and Isola are board-based strategy games; however, which game is played on a 9x10 gameboard similar to Chinese Chess?

full_context: Document 1: Luzhanqi: Luzhanqi () (lit. “Land Battle Chess”) is a two-player Chinese board game . There is also a version for four players. It bears many similarities to Dou Shou Qi, Game of the Generals and the Western board game Stratego. It is a non-perfect abstract strategy game of partial information, since each player has only limited knowledge concerning the disposition of the opposing pieces. Because of the Chinese nature of the game, terms used within the game may vary in translation.
Document 2: Abalone (board game): Abalone is an award-winning two-player abstract strategy board game designed by Michel Lalet and Laurent Lévi in 1987. Players are represented by opposing black and white marbles on a hexagonal board with the objective of pushing six of the opponent's marbles off the edge of the board.
Document 3: Janggi: Janggi (including romanizations changgi and jangki), sometimes called Korean chess, is a strategy board game popular in Korea. The game derived from xiangqi (Chinese chess) and is very similar to it, including the starting position of the pieces, and the 9×10 gameboard, but without the xiangqi "river" dividing the board horizontally in the middle.
Document 4: Shogi: Shogi (将棋 , shōgi ) ( , ] or ] ), also known as Japanese chess or the Generals' Game, is a two-player strategy board game in the same family as Western (international) chess, chaturanga, makruk, shatranj, janggi and xiangqi, and is the most popular of a family of chess variants native to Japan. "Shōgi" means general's ("shō" 将 ) board game ("gi" 棋 ).
Document 5: Chinese chess (disambiguation): Chinese chess primarily refers to xiangqi, a two-player Chinese game in a family of strategic board games of which Western chess, Indian chaturanga, Japanese shogi, and the more similar Korean janggi are also members. This may also refer to:
Document 6: Xiangqi: Xiangqi (), also called Chinese chess, is a strategy board game for two players. It is one of the most popular board games in China, and is in the same family as Western (or international) chess, chaturanga, shogi, Indian chess and janggi. Besides China and areas with significant ethnic Chinese communities, xiangqi ("cờ tướng") is also a popular pastime in Vietnam.
Document 7: Isola (board game): Isola is a two-player abstract strategy board game. It is played on a 7x7 board which is initially filled with squares, except at the starting positions of the pieces. Both players have one piece; it is in the middle position of the row closest to his/her side of the board.
Document 8: Stratego: Stratego is a strategy board game for two players on a board of 10×10 squares. Each player controls 40 pieces representing individual officer ranks in an army. The pieces have Napoleonic insignia. The objective of the game is to find and capture the opponent's "Flag", or to capture so many enemy pieces that the opponent cannot make any further moves. "Stratego" has simple enough rules for young children to play, but a depth of strategy that is also appealing to adults. The game is a slightly modified copy of an early 20th century French game named "L'Attaque". It has been in production in Europe since World War II and the United States since 1961. There are now 2- and 4-handed versions, versions with 10, 30 or 40 pieces per player, and boards with smaller sizes (number of spaces). There are also variant pieces and different rulesets.
Document 9: Hex (board game): Hex is a strategy board game for two players played on a hexagonal grid, theoretically of any size and several possible shapes, but traditionally as an 11×11 rhombus. Players alternate placing markers or stones (Go stones make ideal playing pieces) on unoccupied spaces in an attempt to link their opposite sides of the board in an unbroken chain. One player must win; there are no draws. The game has deep strategy, sharp tactics and a profound mathematical underpinning related to the Brouwer fixed-point theorem. It was invented in the 1940s independently by two mathematicians, Piet Hein and John Nash. The game was first marketed as a board game in Denmark under the name Con-tac-tix, and Parker Brothers marketed a version of it in 1952 called Hex; they are no longer in production. Hex can also be played with paper and pencil on hexagonally ruled graph paper.
Document 10: Abstract strategy game: An abstract strategy game is a strategy game that does not rely on a "theme". Traditional abstract strategy games will conform to the strictest definition of: a gameboard, card, or tile game in which there is no hidden information, no non-deterministic elements (such as shuffled cards or dice rolls), and (usually) two players or teams taking a finite number of alternating turns.
Document 11: Banqi: Banqi () or Half Chess, also known as Dark Chess (暗棋) or Blind Chess (盲棋), is a two-player Chinese board game played on a 4x8 grid, or half of the xiangqi (Chinese Chess) board. Most games last between ten and twenty minutes, but advanced games can go on for an hour or more. Banqi is a social game, usually played for fun rather than serious competition. A more formal version of the game may have evolved into Jungle (board game) and modern Luzhanqi.
Document 12: Dai dai shogi: Dai dai shōgi (大大将棋 'huge chess') is a large board variant of shogi (Japanese chess). The game dates back to the 15th century and is based on the earlier dai shogi. Apart from its size, the major difference is in the range of the pieces and the “promotion by capture” rule. It is the smallest board variant to use this rule.
Document 13: Chaturanga: Chaturanga (Sanskrit: चतुरङ्ग ; "caturaṅga "), or catur for short, is an ancient Indian strategy game which is commonly theorized to be the common ancestor of the board games: chess, shogi, sittuyin, makruk, xiangqi and janggi.
Document 14: Ploy (board game): 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.
Document 15: Subtract a square: Subtract-a-square (also referred to as take-a-square) is a two-player mathematical game of strategy. It is played by two people with a pile of coins (or other tokens) between them. The players take turns removing coins from the pile, always removing a non-zero square number of coins. The game is usually played as a "normal play" game, which means that the player who removes the last coin wins. It is an impartial game, meaning that the set of moves available from any position does not depend on whose turn it is. Solomon W. Golomb credits the invention of this game to Richard A. Epstein.
