Correctly titled, this work will likely be of most use to players rated 1000 to perhaps 1800. However, it is so well written and includes so much valuable information, higher rated players may also benefit.
The section on "Choosing a move" was particularly valuable. It includes a very organized and thorough framework (presented in a 10 point checklist) to utilize in selecting a move. These points include tactical, positional and long-range considerations. I think the incorporation of long-range considerations in the process may be especially enlightening to up-and-coming players. The example games and commentary are truly insightful into the application of the process.
Other chapters include "Defensive Play" (includes some valuable pointers), "Difficult Positions", "Pawn Play" (although for the definite treatment of this subject, see "Pawn Power in Chess" by Hans Kmoch), "Late Middle Game" which addresses open, closed and complicated positions, and more.
Numerous position illustrations, very few typos, very clearly written, handy size, great price. An excellent reference and a super value for the rising, competitive player.
