Please remind me. Was such an ending recently published in Chess Life?
There was at one time an online resource of such endings, but I neglected to capture it.
Thanks,

The best explanation I ever saw of the king, bishop, and knight vs. bare king mate was in Pandolfini’s Endgame Course. I am not ashamed to say that I learned the mate from this book (I had been over 2000 for 15 years at that time.)
The Wikipedia article is OK. I think it’s helpful to tell folks that the knight always moves to a square opposite the color it occupies, so one generally wants to have the knight on the same color square as the bishop. And when the horsie moves, it wants to go back to that color ASAP. (Teaching how pieces coordinate is the best practical reason for teaching KBN v K to young people.)
A couple years ago, some young prodigy was trying to teach me Delatang’s triangle. “I think this is a more efficient method,” he said. Grr 
I didn’t get that far in Pandolfini 
It depends on what you mean by recent and it depends on what you mean by Chess Life. There was an article on this in the October 2007 issue of Chess Life for Kids.
