Originally posted by joesheppeI am a huge fan of all of Glenn Flear's endgame books. They are part of my rep-OTB tournament prep.
(older) -- John Nunn: Chess Move by Move (Amazon for $7. or $8. U.S. used)
(newer) -- Colin Crouch: Modern Chess Move by Move
Both are very good. Still working my way through Colin's, but Nunn's book was memorable: well-written and good production values.
I would also recommend one of many good tomes out on endgames. Glenn Flear's series is a good read. That is, the layout is fun. Endgame reading needs to be fun, eh?
They are not overwhelming, they focus on ideas and understanding, and they are memorable, and easy to recall in the middle of a game.
