In addition to this other kind of Zugzwang, there is another case of a reciprocal zugzwang or mutual zugzwang, an extreme type called trébuchet. A famous example of a reciprocal zugzwang, called trébuchet, is shown below.
The side that has to make a move loses the game.
In this case, it’s white’s move. White can’t move to a square that protect that protects the pawn, unless an illegal move is made. Therefore, white must move away from the pawn, allowing black to capture the pawn, creating a passed pawn, and is then able to push their pawn for pawn promotion.
You can go through the previous moves that were made before this position occurred below.
In some positions, the player who is to move is in zugzwang whether they want to be or not. This kind of position is referred to as a mutual zugzwang or reciprocal zugzwang and are often very interesting positions to study as they are a kind of balanced position.
