Chess

Chess is simply a board game played with 6 pieces each on white and black's side. To win, you have to checkmate the king. If the king is under attack and there is no way to remove the threat immediately, then the king is considered checkmated, and the winning player will gain one point (checkmate 1-0). However, if the game ends in a draw due to insufficient material to checkmate, or because of other reasons, both players gain half a point each (draw 1/2-1/2, stalemate 1/2 - 1/2).

There are 6 pieces in chess: the pawn, rook, bishop, knight, queen and king.

The pawn-It can only advance one square and can capture if a piece is on the immediate diagonal square opposite it. It is able to advance two squares when it is still on its starting square.

The rook-It can move any number of squares horizontally or vertically and can capture if a piece is in its path.

The bishop-It can move any number of squares diagonally and can capture if a piece is its path.

The knight-It can only move in a L-shape (advance three squares horizontally/vertically and move one square horizontally/vertically), and can capture if a piece is on the final square that it lands on.

The queen-It can any number of squares horizontally, vertically or diagonally and can capture if a piece is in its path.

The king-t is only able to advance one square horizontally, vertically or diagonally and can capture if a piece is on the square it moves to. It is the most important piece in the game and if under check (under attack), the check has to be removed in the current move, otherwise it is checkmate and the opponent wins.

On the board, the pieces are arranged in this manner:
Pawn-p, rook-r, bishop-b, knight-n, king-k, queen-q
White-caps, black-small

r-n-b-q-k-b-n-r
p-p-p-p-p-p-p-p

P-P-P-P-P-P-P-P
R-N-B-Q-K-B-N-R

Note that the queens occupy squares of their own colour, and kings occupy squares opposite their colour instead.
