when is a chess game considered a draw
Draw (chess) In chess, a draw is the result of a game ending in a tie. Usually, in tournaments a draw is worth a half point to each player, while a win is worth one point to the victor and none to the loser.
King (chess) In conjunction with a rook, the king may make a special move called castling, in which the king moves two squares toward one of its rooks and then the rook is placed on the square over which the king crossed. Castling is allowed only when neither the king nor the castling rook has previously moved, no squares between them are occupied, the king is not in check, and the king will not move across or end its movement on a square that is under enemy attack.
