If you have 2 knights, you can easily put in prison the other king. Your king
controls the 7.rank. One of your knight controls the c-file or the f-file. But
there isnt a maneuver to mate, because the c/f-controling knight cannot give a
useful check in its next move.

If you have three knights, the controling knight holds its place. The mate is
meanwhile given by the two other knights.

The situation with bishop and knight is completely different. The bishop is
controling the c/f-field. The knight gives a check to b/g and the formerly
c/f-controling bishop mates on a/h.
