Exempel på hur man kan använda ZUGZWANG i en mening

• The concept of zugzwang was known to chess players many centuries before the term was coined, appearing in an endgame study published in 1604 by Alessandro Salvio, one of the first writers on the game, and in shatranj studies dating back to the early 9th century, over 1000 years before the first known use of the term.
• This move has no threat, but it leaves black in zugzwang: Black must either move one of his bishops or rooks, or move a pawn.
• More strongly, when analyzed using combinatorial game theory, many chess positions have values that cannot be expressed as the value of an impartial game, for instance when one side has a number of extra tempos that can be used to put the other side into zugzwang.
