How to Checkmate with Bishop and Knight

This video demonstrates how to checkmate with the bishop and knight. After some experimentation with solving the bishop and knight checkmate, I found that the the first step of simply centralizing ones pieces on the four center squares, with the knight on the same color square as the bishop, is an efficient coordination of the pieces. The knight from such a position is then very quick to becoming optimized in what follows of the Deletang's Triangles, where the king is forced into a large triangle, a medium triangle, and then a small triangle. Once the king is in the small triangle and restricted to exactly two squares, we give checkmate. Practice makes perfect!

    Great method!  I don't think I've ever seen this explained so well. 

    I'll be reviewing this again and again until I have it down cold.

    I think, I am following your procedure without knowing it...
     

    But now with this formula or procedure, we can save a lot of time( after reaching this position may be both players are running out of time).

    Thanks for sharing you very best ideas.

    Thanks for making it so to the point.  One thing I always found interesting with this combination was that there are two other mating positions possible, but they cannot be forced.  (A) Black King at e8, White King at d5, Bishop at d7, and Knight at f6 (e6, f7, b7) mate:

     

     

     

     

     

     

     













    (B)  Black King at g8, White King at h6, Knight at g6, Bishop at d5 mate.

    Nice video, transforms what would at first appear to be a very complex problem into a concise formula.
