The double discovered check <24.Nh5+> places both White knights on the edge of the board!?! Such completely defies Dr. Siegbert Tarrasch's dictum “A Knight on the rim is dim!” Of course, they had a specific job to do there, so it's perfectly fine for a knight to use the edge to "get 'er done!"

One must take into account another chess principle -- that the queen and knight work well together, which FTB attributes to David Bronstein (see IM Nikolay Minev's instructive article that quotes such characteristics to DB: http://www.thechesslibrary.com/arti...).

The White queen and knight pair torture Black into submission, ending five moves later with the royal fork <29.Nf6+> threatening 30.QxQd7# A trait of any knight check is that interposition is not possible to block the check, which Black dearly needs in the final position. What's more, the brilliant finish re-affirms the strategic principle that a knight on the sixth rank is a devastating asset.

We are made to realize that mobility, piece coordination/harmony, FORCE, TIME, and the INITIATIVE are crucial if not dominate elements in a game of chess.
