Board representation in computer chess is a data structure in a chess program representing the position on the chessboard and associated game state. [1] Board representation is fundamental to all aspects of a chess program including move generation, the evaluation function, and making and unmaking moves (i.e. search) as well as maintaining the state of the game during play.
The program's algorithms include an opening book which is a library of opening moves from games played by checkers grandmasters; a deep search algorithm; a good move evaluation function; and an end-game database for all positions with eight pieces or fewer.
Weak solutions exist for somewhat more complex games, such as checkers (with perfect play on both sides the game is known to be a draw, but it is not known for every position created by less-than-perfect play what the perfect next move would be). Other games, such as chess and Go, have not been solved because their game complexity is far too ...
Under USCF rules, if a player completes an illegal move in blitz chess, the player's opponent may claim a win before making a move (if the opponent has enough material to win). One way to claim this win is to take a King left in check by the opponent. Once the illegal move has been answered, the move stands. [75]
Losing chess [a] is one of the most popular chess variants. [1] [2] The objective of each player is to lose all of their pieces or be stalemated, that is, a misère version. In some variations, a player may also win by checkmating or by being checkmated. Losing chess was weakly solved in 2016 by Mark Watkins as a win for White, beginning with 1.e3.

Today's Game of the Day is good ol' Checkers. You know the rules: you can only move diagonally and you can't move backwards. If you're in position to jump over an opponent's piece, you have to do it.
Kings moves as a promoted checkers piece: this is the same type of move as a pawn in this game, but now the king can move and take also diagonally backwards. Capturing of one or more pieces is mandatory. The bishop moves and takes exactly as in normal chess. Capturing is not mandatory.
