"Dear Mr Schuyler,
I happened to see you're a chess.com member in "titled players currently online" so it's easy to send you this note.
Thank you for your efforts put in writing "the dark knight system"! I'm studying it at the moment and enjoying every bit of it. Results in OTB chess are above expectiation :-).
I like the layout of the book very much - theory first and games at the back. Your humor also helps digest all the material quickly.
Again, thanks and please keep writing!
