[6] [10] The number of mathematical operations required to solve chess, however, may be significantly different than the number of operations required to produce the entire game-tree of chess. In particular, if White has a forced win, only a subset of the game-tree would require evaluation to confirm that a forced-win exists (i.e. with no ...
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.
This is a list of chess organizations. Chess is played all over the world. The dominant international governing body of chess is FIDE, which confers titles and conducts world championship tournaments. [1] The first Official World Championship was held in 1886, and there has always been at least one world champion since then. [2]
Chess theory divides chess games into three phases with different sets of strategies: the opening, the middlegame, and lastly the endgame. There is no universally accepted way to delineate the three phases of the game; the middlegame is typically considered to have begun after 10-20 moves, and the endgame when only a few pieces remain.
In the game of chess, an endgame study, or just study, is a composed position—that is, one that has been made up rather than played in an actual game—presented as a sort of puzzle, in which the aim of the solver is to find the essentially unique way for one side (usually White) to win or draw, as stipulated, against any moves the other side plays.
While a chess puzzle is any puzzle involving aspects of chess, a chess problem (or chess composition) is a crafted position with a specified task to be fulfilled, such as White mates in n moves. Chess problems are divided into orthodox and heterodox types, both covering a variety of genres.
Chess initial position. The game of chess is commonly divided into three phases: the opening, middlegame, and endgame. [1] There is a large body of theory regarding how the game should be played in each of these phases, especially the opening and endgame.
He writes: "The chess analogue would perhaps be to count pawn 3, knight 10, bishop 11, rook 16, queen 31 in case of a draw by normal rules, with Black winning ties. It would probably be close to fair, but of course it would be a somewhat different chess." [84] The magnitude of the first-move advantage differs in other variants.
