It only works on the corner(s) that matches the bishop.

It's a fun technique to practice with and can actually show up in your games.  The knight is the especially tricky part but a little calculation should show when to control squares near the bishop's influence to wall off the king.  Then when the king can only shuffle back and force between only two squares just move the knight around until the king is on a desirable square to deliver mate with.

i guess there is not any way to mate in otherside becasue black king can scape from c8 if white move his knight or it will be stalemate:

You can checkmate on the wrong corner, it's just not forced.

True. Like it's possible to checkmate with 2N+K vs K.

In this position it is best to get the black king to the a1 corner:

Try http://www.youtube.com/watch?v=hKwrez7i7fo  but it can,t be done in that corner, only where the bishop matches the corner.

Isn't the first diagram mate in two?

Mate is forced. Bring the king to the edge, then start forcing it towards the right corner.

There is only one maneuver that's difficult - it looks like the king is about to escape but you box him in with the light pieces. Learn this one, and the rest is easy:

 




what after 6.Kc8???

On 6...Kc8 we have the same pattern after 7. Ne7+ Kd8 8. Kd6 Ke8 9. Ke6 Kd8 10. Bb6+.

QuantumKnight shows the key maneuver - the one that screws up most of the players who try and figure it out over the board, including some masters.

It can be a useful exercise with a study partner to take turns defending it.  But as far as how much time to spend learning it, once you understand the trick of using the Knight & Bishop to create a barrier to corral the King, that's what you need.  You will find far more of your games come down to Rook endings, and time devoted to learning those will translate into many more points in practice.


yeah rook end games happen more than these end games but i want learn this too
