Can a king be checkmated with 2 knights?

hey does anyone know if it is possible to check mate your opponent with 2 knights, or a knight and a bishop? Thanks.

2 Knights, Only if its a help mate.

Yes you can mate with a Bishop and Knight.

It is not possible to checkmate with 2 knights. But it is possible with a knight and bishop in about 30 moves with best play from any given starting point.

Yes, in both cases.  Bishop and king can force a mate (although I don't know how to); but 2 knights needs opponent to blunder.

Here's a guide created by Sqod:

KNNKP can be decisive with best play from both sides, this is a textbook endgame however.

Yes, I was going to say when pawn(s) are left on the board they can block off escape routes, and also avoid stalemates, enabling forced mates.
