How do I checkmate with K + B + N?
Sort:
the check mate position is this.....above.But it is impossible to make,so its a draw:)

I have a book that has a sequence of forced moves leading to it. Unfortunately, that's all it gives. And so the pattern to this "basic" checkmate continues to elude me.

Most players will never encounter this endgame in a career of playing chess - Wikipedia states that it occurs about once in 5000 games !
So do you really want to put serious work into studying a position that is so unusual ? I think the advice to offer a draw is good.
Of course if you want to study this for it's own sake then Wiki' offers some very good information - look for the 'W' method & Delatang's triangles !
It is pretty easy to master. Anyone should be able to learn in within an hour at the most.
1. Drive the king to the edge (simple). If it runs into the bishop's colored corner, just checkmate it.
2. If it runs into the "wrong" corner, create the following setup:
This is btw. played without ny literature assistance or something like that. After I wrote down the moves I checked it with tablebases and it is indeed the optimal solution!
So you can not only train how to mate, but also how to do it effectively and prevent any 50-moves issues.
3. I have been playing chess for 20 years now and I had this ending in exactly one serious game. I solved it over the board within 5 minutes without knowing the exact moves ....

Uhh Knight Bishop and King vs lone king is a forced win

The optimal solution ? Not sure about that because I think you may have made an error at move 7.Ke7 which allows the black king to escape via d5 - I just can't see any quick way of recapturing him.
Surely 7.Bc4 is the correct move ?
Anyway, thanks for the diagram (still very useful) - it's helped to clear up some of the confusion I had about this mate !
Mastering this endgame is a good exercise. It never happens in practice, but it can teach you a lot about piece coordination.
So it's well worth it to study it in my opinion.
Once the enemy King is against the edge (even in the wrong corner) than it's easy because there's a method. The real challenge is pushing the King against the edge. Even with perfect play (e.g. Rybka) it can take around 30 moves if the King starts in the centre and puts up a good defence.
To mate the opponent you have to do the following steps:
1. Drive the king to the edge
2. When the king goes to the wrong corner (where the corner color is another color then the bishop) try to achieve the following diagram:
3. If the king goes to the right corner, checkmate it
Hard games.

I have had this ending twice in tournament games. Both times ended in checkmate. Once I was on the winning end, and once I was on the losing end.
with accurate play checkmate with just BIshop and Knight isn't possible

No, you need the king too.
From all basic endgames that exist is the frequency of a K+N+B vs. K 0.02%
I agree. But, if you meet with an opponent that fast, you would not be able to win. This is because they are clever escape until the game ends in a draw

This actually happened in one of my games the day after I learned it
"fischerandchips" !! brilliant!

I use the method of Deletang's triangles which I've heard is easier than the edge method.
I know it's a basic checkmate, but I haven't figured out any pattern to it. I'd asked the sponsor of my school chess club and he couldn't explain it, though he could do it. He said to just offer a draw.
