Chess is one of the most popular strategy game in the world. This is a two player board game. The game board is a check board which is arranged in an eight-by-eight grid with total 64 squares. The game begins with 16 pieces: one king, one queen, two rooks, two knights, two bishops, and eight pawns.
Each of the six piece types move differently and the objective is to checkmate the king of the opponent. Here the word checkmate means capturing the king such a way so that he can’t escape or move anyway freely. This way the game goes on from the very first by attacking the pieces of the opponents and by creating threats for the opponent’s king.
The chessboard is of eight rows (called ranks and denoted with numbers 1 to 8) and eight columns (called files and denoted with letters a to h) of squares. The chessboard is placed with a light square at the right-hand end of the rank nearest to each player, and the pieces are set out as shown in the diagram and photo, with each queen on a square of its own color. The game pieces are divided into white and black sets, and the players are referred to as "White" and "Black" respectively by convention.
Each chess piece has its own style of moving.
· The king moves one square in any direction. The king has also a special move which is called castling and involves also moving a rook.
· The rook can move any number of squares along any rank or file, but may not leap over other pieces. Along with the king, the rook is involved during the king's castling move.
· The bishop can move any number of squares diagonally, but may not leap over other pieces.
· The queen combines the power of the rook and bishop and can move any number of squares along rank, file, or diagonal, but it may not leap over other pieces.
· The knight moves to any of the closest squares that are not on the same rank, file, or diagonal, thus the move forms an "L"-shape: two squares vertically and one square horizontally, or two squares horizontally and one square vertically. The knight is the only piece that can leap over other pieces.
· The pawn may move forward to the unoccupied square immediately in front of it on the same file, or on its first move it may advance two squares along the same file provided both squares are unoccupied or the pawn may capture an opponent's piece on a square diagonally in front of it on an adjacent file, by moving to that square. The pawn has two special moves: the en passant capture and pawn promotion.
Once in every game, each king is allowed to make a special move, known as castling. Castling consists of moving the king two squares along the first rank toward a rook (which is on the player's first rank[note 1]) and then placing the rook on the last square the king has just crossed. Castling is permissible under the following conditions:
§ Neither the king nor the rook may have been previously moved during the game.
§ There must be no pieces between the king and the rook.
§ The king may not be in check, nor may the king pass through squares that are under attack by enemy pieces, nor move to a square where it is in check.
· En passant
When a pawn advances two squares from its starting position and there is an opponent's pawn on an adjacent file next to its destination square, then the opponent's pawn can capture it en passant (in passing), and move to the square the pawn passed over. However, this can only be done on the very next move, otherwise the right to do so is forfeit.
When a pawn advances to the eighth rank, as a part of the move it is promoted and must be exchanged for the player's choice of queen, rook, bishop, or knight of the same color. Usually, the pawn is chosen to be promoted to a queen, but in some cases another piece is chosen; this is called underpromotion.
When a king is under immediate attack by one or two of the opponent's pieces, it is said to be in check. A response to a check is a legal move if it results in a position where the king is no longer under direct attack (that is, not in check). It is illegal for a player to make a move that would put or leave his own king in check.
The chess game may be drawn or won according to the players’ agreement or following the rules above. So this is all about chess in brief although it is a huge topic but it is enough to get hand on it. so play chess and enjoy!
