user9002: What are the minimum sets of pieces required for checkmate when the opponent has no other piece that the king?

user9003: There are many answers to your question, 

1) A rook 
2) Any 2 minor pieces (Minor pieces:  Bishop, Night)
3) A Queen
4) 1 pawn :)


user5653: As simple as a Knight or even a pawn, if you consider the fact that your opponent's pieces can block the escape squares too. 
Example: 
W: Kf1, Nf2
B: Kh1, h2. 
The Assume that white played Nf2# in the last move. So, white has just used one knight to checkmate black king. 

user70: 
King + Bishop + Knight
King + Bishop + Bishop 
King + Rook
King + Queen
and don't forget the unlikely King + Knight + Knight + Knight

Assuming the lone King is attempting to avoid checkmate.
