1.The game of chess is played between two opponents who move their pieces alternately on a square board called a ‘chessboard’. The player with the white pieces commences the game. A player is said to ‘have the move’, when his opponent’s move has been ‘made’. (See Article 6.7)
2.The objective of each player is to place the opponent’s king ‘under attack’ in such a way that the opponent has no legal move. The player who achieves this goal is said to have ‘checkmated’ the opponent’s king and to have won the game. Leaving one’s own king under attack, exposing one’s own king to attack and also ’capturing’ the opponent’s king are not allowed. The opponent whose king has been checkmated has lost the game.
At the beginning of the game one player has 16 light-coloured pieces (the ‘white’ pieces); the other has 16 dark-coloured pieces (the ‘black’ pieces)....
These pieces are as follows:
A king, usually indicated by the symbol "K"
A queen, usually indicated by the symbol "Q"
Two rooks(Tower), usually indicated by the symbol "R"
Two bishops, usually indicated by the symbol "B"
Two knights, usually indicated by the symbol "k"
Eight white pawns, usually indicated by the symbol "P"
