Mansuba

A mansuba is a position from the shatranj tradition prepared for instruction or as a challenge to solve. Instead of beginning from the normal starting position, it presents a specific situation and a task, such as finding a win, forcing checkmate, or securing a draw.

The position was usually composed, although it could resemble a plausible moment from play. Some mansubat, the plural of mansuba, were transmitted with memorable stories, but the narrative does not define the form. The essential elements are the position and the result to be demonstrated.

It must be solved with the relevant historical rules. A queen-like piece may be a ferz moving one diagonal square, while a bishop-like piece may leap exactly two squares. Applying modern movement changes the problem.

The mansuba is an ancestor of modern chess problems and studies, meaning created positions with a precise task. It does not necessarily follow current conventions about solution length, economy of pieces, or the presentation of variations.
