I like the video. The ability to talk while pointing at the squares makes it probably easier to communicate some of the main ideas of this mate.
On the other hand I think that the diagrams in my own post make it easier to remember.
Probably a combination of both lessons is best.

I thought you might be interested in a video I made a while ago that explains how to checkmate with bishop and knight vs. the lone king.

Here’s the video: http://www.chessvideos.tv/forum/about802.html

thank you also for stopping by. the pictures, yes, i accumulate them or select them for indeterminate future use, as distinct from writing posts then having to go find them on the spot, if you will. when my writing is done, i go to my library and simply select or hunt through them for an image to suitable feeling.

of course, im highly trained in a visual field from long ago in many modalities… which cannot hurt… but, without good readers such as yourself, there is diminished motivation to do so.

warm regards, david in seattle

(Though I have to say I wish I had used that time differently. I know they say that this is useful for learning piece coordination even if it never comes up in practice, but I think there are equally good (for coordination) but more practical positions to focus on, such as mating with two bishops, or even a single rook).
