I assume this means ... a king with only a king and two knights.

I don't like to be pedantic but this is not true.  It is possible.
However, it cannot be forced.  There are some positions where a king
and two knights can force mate against e.g. a king and a pawn.  In these
cases the extra material converts a draw into a loss.  This might be of
interest.

Chessplayers of the world unite.
