This is not for the purposes of the on-going game, is it? I'm not sure, but that might not be in accordance to the site rules.

It might be an idea...
...to revisit this after the game has ended. You can show us how you did it, or ask where you went wrong, depending on the outcome.
Cheers,

Wikipedia has it
Why even ask here?

Why not...?
I agree: Wikipedia has it, as does the link left by blake78613. But methinks there is more behind. How many of us know the (or even 'a') winning procedure without looking it up?

Acyually, I have learned something from this thread. This even though I have won all three KBN vs K endings that have ever come my way. I've long known which corner to aim for, but it was how to chivvy the enmy King in the right direction from a 'general' position that I was never completely sure about. Once the game in question ends, I might dilate on this...

K vs K, N, B
This end game is most difficult of all. I wanted to see if my opponent could work it.

the time to learn and the tools for learning
Before we squish a student's head in for asking a question, I think any legitimate inquiry should be encouraged. And we have legitimate tools to use when we pull at our brains like pulling on the handle of a slot machine to line up the right combination.

And I feel the best time to learn, whether from theory or from past master games, is the time of one's greatest motivation: and that is while you still are playing a game, not afterwards.

So for instance, when I had a particularly baffling B + 2 p versus R + 2 p endgame, I read Pal Benko's articles on the endgame to give me a frame of reference within which to build and develop an understanding for bishop versus rook combats that end in draws. To build up a feel for the pieces and where "they" wished to be.

When I faced a difficult R + P endgame that seemed to mirror the final game in the last Capablanca-Lasker match for the World Championship, sure, I looked at their game -- plus I looked at 7 different books that analyzed the Capablanca-Lasker WCh endgame, and Capalanca's choice, and his procedure for winning.
Capablanca's solution made no sense to me, not even with the elucidation of textbooks, so I chose my own path, and happened to win.
Did looking at the theory of rook endgames specifically help? No; but it gave me the conceptual constructs on which to imagine a win, and visualise it, and build a plan, and carry it out. When I do look at grandmaster examples, for instance, the games of Korchnoi and Speelman and Avrukh and Georghieu, I generally mention it to my opponent, so we have something to discuss with words as well as pieces.

As I recall the (now-deleted) question originally posed here, I believed it was phrased as a general question about a type of endgame, and NOT a call for a recipe for winning one particular, ongoing game; that of course would have broken our rules, and that would have taught this player Nothing.

How I learned it
Practicing it on your own is tedious, but Chessmaster software has this ending under "Drills" in
the Academy.

Forget about the chase...
... Black cut to the capture, and walked into a one-move mate ...Ka4(?). An oversight... or a form of resignation? White had a mate in 6 anyway after ...Ka2.

End Game K vs K, N, B
Thank you all for your interest in this subject.

Incidentally...
That 'sudden death' mate ought to alert one for future reference that although there are just two squares on the board at which K,N,B can FORCE mate against a lone King (in the above case, a1 and h8), mate may be DELIVERED at any side square. The threat of mate in one can be used to drive the King where the attacker wants to go, on pain of an abbreviated existence, as here.

Here's something interesting. During an endgame, when you're pawns are attacked by say a R. So you have one R against the other R but your WR is protecting the P, you don't want to put that P on your color. I recently learned this yesterday.

... I'm not sure I understand what you are saying. Maybe a diagram would clarify?

I think you are getting confused between rooks and bishops, since as far as I know color of the square that you place either a pawn or rook shouldn't really matter in a rook endgame. However when bishops come into the equation it is another matter and the color of the squares you chose to place your pieces should be carefully considered

Or maybe, my coach got confused.

Here's another important thing about endgames. You know how taking your time, thinking, and concentrating are important. In endgames, however, they are critical and essential as one mistake often makes a difference between a win and loss. That is shown in the annotation below. gameknot.com
