Bad Bishop
A bishop whose mobility is restricted by its own pawns occupying squares of the same color.
A bad bishop, sometimes fixed behind its own pawn chain, often becomes a long-term positional weakness, especially in endgames where its limited scope cannot compensate for the opponent's more active pieces.
Etymology
No coinage, coiner, or first citation for bad bishop was found in the sources fetched for this project, so the historical fields are left empty rather than invented. Wikipedia's dedicated article and its chess glossary both define the term without any etymological discussion: a bad bishop is a bishop that is hemmed in by the player's own pawns. The paired term good bishop is defined by contrast, and Wikipedia's article on the bad bishop hosts a cluster of related structural definitions without dating any of them. The concept belongs to the general vocabulary of positional chess that consolidated in the Steinitz-to-Nimzowitsch era, but no source consulted attributes the phrase itself to any writer or date. Editors should present it as descriptive terminology of undocumented origin.
