Don't bother, it's a waste of time.

fianchetto123

that wasnt exactly the answer I was hoping for

it came up in a game the other day, and I only got a draw...so its not a waste of time is it

VanillaKnightPOC

Compared to all the other endgames you could be studying it is.

Besides, I'd have thought you would've figured it out OTB.

u need2play w/it till u get the king in the corner that matches wateva squares ur bishop is on.

VanillaKnightPOC

You have to use all 3 pieces to do this.

Coach-Bill

Ok aim for a prime position. you want to memorize this no matter what color square your bishop ison, it will always work....Remember, you can only force mate in corner of the color of the square of your Bishop.

 

White K f6, N f7, B on b1 to g6 Diagonal

Black K f8. 

 

Now, play, as white Bh7.

Black must play Ke8.

White now plays Ne5

If black plays Kf8, just strive to recreate prime position, except now two files over. THen, the rest is easy....

 

If Black plays Ke8, your Knight and King do a little dance. Black tries to head for opposite corner. 

 

so....

1.... Ke8

2. Ne5 Kd8

3. Ke6 Kc7

4. Nd7 Kc6

5, Bd3!  and knight and Bishop cut the King off.

5.... Kc7 

6. Bb5

 

the rest is rather easy....I'll be back, try this part out first.

Thank you for devoting some time to helping me with this sir

Meh, try queen and king v rook and king.

Slowly force the king back to a corner. If they are smart they will go to the opposite color of your bishop. Then memorize this type of pattern, and slowly drive the king to the correct corner. The mate is actually rather easy, the only hard part is that you are only allowed 50 moves before it is a draw, so accurate play is required. And even though this ending is extremely rare (as others have pointed out), learning how the knight and bishop coordinate will help your chess a lot.

I had that in a OTB game just yesterday and won it

fianchetto123

queen vs rook not bishop and knight vs king i mean

shepi13

It's easier if black plays the passive defense

shepi13

Q vs R is a much harder ending at high levels than N+B v K. However, at our level no one knows how to defend Q vs R, making the win quite easy, while N+B is still a slightly difficult checkmating pattern to memorize and find OTB.

very easy to understand video, with a very simple, easy to remember method. http://www.youtube.com/watch?v=PWZ7h2yrJME

There are a couple of videos on youtube which explain the principles quite well; once you understand the way the pieces are working together to simultaneously limit the movements of the king and to drive him in the right direction, just set up random positions on your engine with the 4 figures and work on getting it done in under 50 moves; sooner or later you´ll have it.

Your welcome. Seems you have several correct solutions now. I have a bunch of elementary mates on my website, on my Chess4Kids page, but hadn't done this one yet:

So, I made a video on another chess server, so they match. People say my videos are entertaining, I hope I don't disappoint. I have seen this ending come up 4 times in tournament play, and the defender, a master, scored 3 draws and a loss! (I was the master twice and got 2 draws). Who lost? A famous future GM to a famous future IM.

I think the B+N checkmate is worth studying. Although it rarely occurs, by studying it you learn a tremendous amount about piece coodination. It's amazing how you can build and inescapable net with those two pieces

I agree 100%. It always amazes me when (strong) players say it's a waste of time to learn this. Heck, even I could learn this in a day, and every now an then when I remember, I practice it against a few engines.

And there are definite measurable benefits. You now know that if the Knight is on x, y should be good for the bishop..

rooperi, when I was rated 1560ish it took me a couple weaks of hard work before I could checkmate with B+N consistently within 50 moves (granted, it's a lot harder when you're playing a tablebase computer than when you're playing lower rated chess players). It took me a few months to learn Q v R checkmate, which is much harder.

rooperi

shepi, for me the hardest part is driving the king to the corner (even the wrong corner).

Once it is there, it is only a single maneuvre you need to remember, the king's escape is an illusion.

In your post #13 I think Black can make it much harder for white, which is where most attackers fail:
