Insufficient mating material
Insufficient mating material describes a position in which neither side has enough pieces to deliver checkmate by any legal sequence, which the Laws treat as a dead position and a draw.
The Laws do not list particular piece combinations. They use the dead-position test, so the real question is whether any series of legal moves, from either side, could reach checkmate. A bare king cannot mate, and neither can a king with only one bishop or only one knight. A pawn that can still advance usually keeps mate possible, because it can promote to a queen; only when every pawn is permanently blocked can the position still be dead. Two knights against a bare king are also not dead under that test. They cannot force mate, but a cooperating defender can be mated, so the game continues. King and bishop against king and bishop splits the same way: with bishops on the same color no mate is possible, so the position is dead, while with bishops on opposite colors a mate can occur if the defender plays badly. The distinction has a practical use at the clock. If your opponent flags but you hold material that could never produce checkmate, the game is drawn. Before you hunt for a win on time in a thin ending, check which of these cases you have.
Also worth reading is Dead position. A dead position is one in which checkmate can no longer happen for either side, however the moves go and however cooperative the players are, and the game ends as a draw the moment it arises.
Compare it with Insufficient material. Insufficient material is the situation where the pieces left on the board could not produce checkmate for either side even if the opponent cooperated fully, so the position is dead and the game ends drawn.
A neighboring idea is Fivefold repetition. Fivefold repetition is the rule that a game is drawn automatically, with no claim needed, once the same position has appeared at least five times.

Flagging is winning, or claiming to win, on time because an opponent's clock has run out; the flag-fall loses the game unless the other side could never checkmate.
Stalemate is a draw that occurs when the side on move has no legal move at all while its king is not attacked, so the game ends on the spot with half a point to each player.
A draw by agreement ends the game with a half point each when both players settle on a draw, which the Laws allow once each has made a move unless the rules of the event restrict it.
Piece value is the rough points scale players use to compare material: a pawn counts one, a knight and a bishop three each, a rook five and a queen nine.
