Chess: 1 or 2 players free for everyone.

Chess is a game between two people, each of which has 16 moving pieces that are placed on a board divided into 64 squares.

In its competition version, it is considered a sport, although at present it clearly has a social and educational dimension.

It is played on an 8 × 8 squared board alternated in black and white, which constitute the 64 possible positions of the pieces for the development of the game. At the beginning of the game each player has sixteen pieces: a king, a queen, two bishops, two knights, two rooks and eight pawns. It is a strategy game in which the objective is to "overthrow" the opponent's king. This is done by threatening the square the king occupies with one of his own pieces without the other player being able to protect his king by interposing a piece between his king and the piece that threatens him, moving his king to a free square or capturing the piece that is threatening him, what he brings as a result is checkmate and the end of the game.
