Chess is a board game for two players, called White and Black, each controlling an army of chess pieces, with the objective to checkmate the opponents king. It is an abstract strategy game that involves no hidden information and no elements of chance. The game is played on a chessboard with 64 squares arranged in an 8×8 grid. Each player controls sixteen pieces: one king, one queen, two rooks, two bishops, two knights, and eight pawns. The game is won by checkmating the opponents king, i.e. threatening it with inescapable capture. Chess is a turn-based strategy game with no hidden information, and the element of luck is virtually non-existent in the game. Chess has a rich history, with origins dating back to at least the 6th century in India. It has connections with other fields such as mathematics, computer science, and psychology. Chess is also known for teaching important life skills to children, such as critical thinking, problem-solving, and decision-making.
