fredthebear: <GrahamClayton: Has anyone read his book "Chess Tactics"? It looks well thought out, with explanations, examples and then quizzes.>
Yes, "Chess Tactics" is a terrific "little" book that I much prefer over longer books. It has 307 puzzles; most solutions are 3 moves. The Table of Contents includes: Introduction, Pins, Skewers, Double Attack, Discovered Attack, Back Rank Combinations, Overloading, Deflection, Decoying, Removal of Defence, Interception, Space Clearance, Zwischenzug, Pawn Promotion, Draw, Miscellaneous Problems, Solutions, Bibliography. It's material is of intermediate difficulty, probably not a first book of tactics for a beginner. First published by The Crowood Press Ltd 1984. Reprinted by Batsford in 2004. I'm not aware of any editing differences. Kindle currently sells "Chess Tactics" for $7.99.
IMHO, "Winning Chess Tactics for Juniors" by Lou Hays is less satisfying to read, slightly more difficult than Paul Littlewood's gem. Hays offers 535 diagrams, a good follow-up. This is the most challenging "Juniors" book that I'm aware of, although I suspect GM Joel Benjamin's new "World Champion Chess for Juniors" is plenty to consider.
BTW, "Chess Tactics" by Alexander Kotov is NOT about tactics. Kotov's book from the same era is about situational combinations, mostly finishing combinations. Typically, there's one diagram per column w/a brief explanation of the game situation. (At times, an entire game is given.) Most game fragment solutions are 5-8 moves long in story form, instead of listed in the back of the book. It's a pleasant read but not easy, perhaps intermediate and advanced level (one should have a strong grasp of tactics already). Kotov's "Chess Tactics" book was translated and edited by John Littlewood; printed in Great Britain but published in 1983 by American Chess Promotions. I'm not aware of modern reprints - it's often available used for a reasonable price.
By comparison, Fred Reinfeld's "Complete Book of Chess Stratagems" (Dover publishers) is also mistitled. It's a testy puzzle book of grandmaster combinations without written explanation, a challenging follow-up to Kotov's book. Reinfeld's book features English Descriptive notation, the others use algebraic notation. It takes a strong analyst to smash through Reinfeld's book without tips.
Anyone who can accurately handle the older books just mentioned certainly has master ability to calculate. Of course, there are many modern chess puzzle books that are just as useful.
