Insufficient Material
Insufficient Material: A draw because no legal sequence can produce checkmate with the remaining pieces.
In-Depth Explanation
King versus king, king and bishop versus king, and king and knight versus king are standard insufficient-material draws. Similar-looking positions require care: two knights cannot force mate against a bare king, but mate can be legally possible when the defender has another piece or pawn.
