A variant first described by Claude Shannon provides an argument about the game-theoretic value of chess: he proposes allowing the move of “pass”. In this variant, it is provable with a strategy stealing argument that the first player has at least a draw thus: if the first player has a winning move in the initial position, let him play it, else pass.
A solved game is a game whose outcome (win, lose or draw) can be correctly predicted from any position, assuming that both players play perfectly.This concept is usually applied to abstract strategy games, and especially to games with full information and no element of chance; solving such a game may use combinatorial game theory or computer assistance.
The game of chess is not solved, meaning it has not been determined with certainty whether a perfectly played game would end in a win for White, a draw, or even a win for Black. Due to its high level of complexity and the limitations of computer technology it is considered unlikely that it will be solved in the foreseeable future.
Other games, such as chess and Go, have not been solved because their game complexity is far too vast for computers to evaluate all possible positions. To reduce the game complexity, researchers have modified these complex games by reducing the size of the board, or the number of pieces, or both.
Maharajah and the Sepoys, originally called Shatranj Diwana Shah and also known as the Mad King's Game, [1] Maharajah chess, [2] or Sarvatobhadra "auspicious on all sides", [3] is a popular chess variant with different armies for White and Black. It was first played in the 19th century in India. It is a solved game with a forced win for Black.
The modern rules of chess emerged in Europe at the end of the 15th century, with standardization and universal acceptance by the end of the 19th century. Today, chess is one of the world's most popular games, with millions of players worldwide. Organized chess arose in the 19th century.
