CHECKERS VS JANGGI

Draughts (/drɑːfts, dræfts/; British English) or checkers (American English) is a group of strategy board games for two players which involve diagonal moves of uniform game pieces and mandatory captures by jumping over opponent pieces. Draughts developed from alquerque. The name 'draughts' derives from the verb to draw or to move, wheras 'checkers' derives from the checkered board which the game is played on. The most popular forms are English draughts, also called American checkers, played on an 8×8 checkerboard; Russian draughts, also played on an 8×8, and international draughts, played on a 10×10 board. There are many other variants played on 8×8 boards. Canadian checkers and Singaporean/Malaysian checkers (also locally known as dum) are played on a 12×12 board. English draughts was weakly solved in 2007 by a team of Canadian computer scientists led by Jonathan Schaeffer. From the standard starting position, both players can guarantee a draw with perfect play. Draughts is played by two opponents, on opposite sides of the gameboard. One player has the dark pieces; the other has the light pieces. Players alternate turns. A player may not move an opponent's piece. A move consists of moving a piece diagonally to an adjacent unoccupied square. If the adjacent square contains an opponent's piece, and the square immediately beyond it is vacant, the piece may be captured (and removed from the game) by jumping over it. Only the dark squares of the checkered board are used. A piece may move only diagonally into an unoccupied square. When presented, capturing is mandatory in most official rules, although some rule variations make capturing optional. In almost all variants, the player without pieces remaining, or who cannot move due to being blocked, loses the game.

Janggi (including romanizations changgi and jangki), sometimes called Korean chess, is a strategy board game popular in Korea. The game was derived from xiangqi (Chinese chess) of China 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. Janggi is played on a board nine lines wide by ten lines long. The game is sometimes fast paced due to the jumping cannons and the long-range elephants, but professional games most often last over 150 moves and so are typically slower than those of Western chess. In 2009, the first world janggi tournament was held in Harbin, Heilongjiang China. The board is composed of 90 intersections of 9 vertical files and 10 horizontal rows. The board has nearly the same layout as that used in xiangqi, except the janggi board has no "river" in the central row. The pieces consist of disks marked with identifying characters and are placed on the line intersections (as in xiangqi and Go in China). Janggi pieces are traditionally octagonal in shape, and differ in size according to their rank. The sides are Blue (or sometimes Green), which moves first, versus Red. Each side has a palace that is 3 lines by 3 lines (9 positions) in the centre of their side of the board against the back edge. The palace contains four diagonal lines extending outwards from the centre, forming an "X" shape.
