58 ( +1 | -1 ) MateIf you want to mate your opponent with a knight and bishop you must get his king in the corner which is of the same colour as your bishop. Your opponent will of course try to avoid this and move his king against one of the two others corner. First you must get his king to an edge. To manage this you must let your knight take control of the opposite-coloured squares of your bishop. Then you can force the king into the right corner, by using a "W-system" with your knight. The best is to try at this yourselves at home and see if you manage...
71 ( +1 | -1 ) I agree with Danny SparksThe K + B + N versus K (what I call the Cinderella Mate) is an excellent exercise in handling a combination of awkward pieces. I teach it ONLY for that purpose, and ONLY to intermediate students.
I believe it is a mistake to master the Cinderella for any other reason. I have played it only once in my career. I know a national master who has never played it.
The way I treat the Cinderella is by breaking it down into four landmarks: Cin - der - el - la. By treating the mate as four separate, consecutive problems, the process becomes easier to remember.
Every endgame book on the market today, and in the past, except mine, has a complete process for the Cinderella. Go to the library and borrow an endgame book. You will find that mate there.
K+B+N vs K is an elementary endgame, the K+B+N side always wins. You only need to know the logic of it, which is very simple.
You could practice this endgame against a friend, with clocks. Give your friend the K and ask your friend to learn the mechanics of this endgame in order that he can play the best defensive moves. (In the most disadvantageous positions the strong side must need 35 moves approx. to checkmate, so be careful to not exceed the 50 moves rule ).
Once you have dominated this endgame, adjust the clocks: 10 minutes for your opponent, 1 minute for you.
