Stalemate if it is Black to move. It isnot checkmate, and since Black cannot move, the game is a draw.
Although the objective of the game is to checkmate the opponent, chess games do not have to end in checkmate—either player may resign which is a win for the other player. It is considered bad etiquette to continue playing when in a truly hopeless position. If it is a game with time control, a player may run out of time and lose, even with a much superior position. Games also may end in a draw (tie). A draw can occur in several situations, including draw by agreement,stalemate, threefold repetition of a position, the fifty-move rule, or a draw by impossibility of checkmate (usually because of insufficient material to checkmate). As checkmate from some positions cannot be forced in fewer than 50 moves (such as in the pawnless chess endgameand two knights endgame), the fifty-move rule is not applied everywhere,particularly in correspondence chess.
