Extended meaning of PLACHUTTA [closed]
Chess is one of the few sports that offers a cornucopia of words, which are used in ordinary parlance. checkmate, stalemate, zugzwang, and gambit are a few well-known words that owe their origin to the sport of chess.
I came across a new chess word very recently: plachutta.
Here is how Wikipedia defines the word:
The Plachutta is a device found in chess problems: a white piece sacrifices itself on a square where it could be captured by one of two similarly moving black pieces (for example, a bishop and a queen moving along a diagonal, or two rooks) moving along a different line; whichever black piece captures, it interferes with the other.
My question is how could this word be used in an ordinary context like we use the other chess terminology.
Seeing as only people interested in chess problems will know the reference, I question the usefulness of using the term "Plachutta" for any metaphorical sense. By the way, this chess tactic is named Plachutta after a chess problemist Joseph Plachutta; it is not an ordinary vocabulary word.
To explain in more detail: There are White pieces A1, A2, C and Black pieces B1, B2. White has 2 threats A1->W1, A2->W2. B1 guards W1; B2 guards W2; their lines of guard cross at X. White plays C->X. If B1 takes at X, B1 is overloaded: it must now guard both W1 and W2. So now White plays A2->W2. Black must now take at W2 with B1 rather than B2, because B1 is in B2's way -- B1 interferes with B2. White has now decoyed B1 away from where Black wanted it. White now plays A1->W1 which Black cannot parry because B1 no longer guards W1.
I can't see any situation where the chess term for this specific set-up would be a better metaphor than a well-known word such as "overload", "interfere" or "decoy".
