The object in chess is to checkmate your opponent's King. Checkmate, or just "mate" occurs when a king is attacked and the king cannot escape capture on the next move.
Chess is played on a board with 64 squares set up in the following way:
The Rooks begin the game in the corners. The Knights (many beginning players call them horses) are next to the Rooks. The Bishops start next to the Knights. And then the King and the queen.
Note that white and black Queens both begin the game on squares of their color. The white Queen begins on a white square. The black Queen begins on a black square.
And, at the beginning of the game, always start with a white square in the lower right corner of the chessboard.
TO BEGIN THE GAME, white moves first, and then black... taking turns until CHECKMATE, or one player RESIGNS, or both players agree to a draw.
