Concept

Worst piece

You might say: worst-placed piece, least useful piece

The piece contributing least to the position. Improving its route, target, or defensive role often improves the whole army at once.

What it does
Provides a practical quiet-move test when no forcing move dominates, and exposes whether a piece should improve or be exchanged.
Ask
Which of my pieces contributes least, and what useful square, route, target, or defensive job can it gain?
Typical
Least useful piece; useful route; useful target; defensive role; exchange candidate.
Trouble
The same piece remains idle while the opponent improves, or a slow improvement ignores an urgent threat.
