The term CHESS ENDING refers to the various ways a game of chess can end. The most common way is MATE, which is when one player has no legal moves and their king is in check. This is also known as CHECKMATE, which is when the king is in check and cannot escape. Another way a game of chess can end is ESSES, which is when both players agree to end the game without a winner or loser. Finally, a game of chess can end in a DRAW, which is when neither player has enough pieces to CHECKMATE the other.
