Shereshevsky does have a somewhat well known endgame book called endgame strategy.
Kotov is well known for his book "Think like a Grandmaster" where he elaborates on his systematic method of calculation with the "tree of analysis"
I don't know of any author whos last name is cassia backwards. Doesn't sound like the actual author's name does it :) How long ago was it? I've been told Reinfield was the only author available to united states player before the Fischer boom launched a new era in english books on the subject.
I've read through and played through dozens of chess books over a long life. Here are a few favorites, but I can't remember their titles! Can you help me out?
The first was old and small when I read it. It's author: "Assiac" ("Caissa" backwards, get it?) I was enthralled with what for me was the brand new world of K+P endings, opposition play, etc.
The second was by feared Russian tactician Alexander Kotov. He started by telling of the time his tactics, calculation of variations, etc., simply stunk. Mine did too, then, so I really got into Kotov's method of learning to calculate. But I don't remember the title.
Finally, a book by another Russian, Shereshevsky, excellent on endgame strategy, which may have been the book's name, but I'm not sure. . .
