In chess, what is the position in which all moves are disadvantageous is called?

Chess is a two-player strategy board game played on a chessboard, a checkered gameboard with 64 squares arranged in an 8×8 grid. The game is played by millions of people worldwide.

Each player begins with 16 pieces: one king, one queen, two rooks, two knights, two bishops, and eight pawns. Each of the six piece types moves differently, with the most powerful being the queen and the least powerful the pawn. The objective is to checkmate the opponent's king by placing it under an inescapable threat of capture. To this end, a player's pieces are used to attack and capture the opponent's pieces, while supporting each other. In addition to checkmate, the game can be won by voluntary resignation of the opponent, which typically occurs when too much material is lost, or checkmate appears unavoidable. A game can also in several ways end in a draw.

Zugzwang: A situation in which a player is limited to moves that cost pieces or have a damaging positional effect or A situation in a chess game in which a player is forced to make an undesirable or disadvantageous move.

According to Nimzowitsch, writing in the Wiener Schachzeitung in 1925, this term originated in "Danish chess circles.” But the man who popularized the word was the immortal Aaron Nimzowitsch himself in his classical books “My System” and “Chess Praxis.”
