Is there any book that focus on pattern recognition

This was an interesting article :

matzleeach, from what perspective?

As far as its accuracy as a theory and how many patterns are necessary for varying levels of play, there are many scientific white papers discussing this:

As far as practical methods, check out Chessimo, De La Maza's book Rapid Chess Improvement, the Leitner System, or Supermemo. These each suggest schedules for spaced repetition (review) that reduce the amount of time it takes to learn.

As far as sources for patterns, most chess books and software. :)

From a practical method.  thanks

For consideration:

In Jonathan Tisdall's excellent book "Improve Your Chess Now", he provides a chapter on "Pattern Training" (positional themes and tactical patterns) and follows with two sections on mating patterns and common tactical themes. Warmly recommended.

Also:

A wonderful Dover reprint, "The Art of Checkmate", by Georges Renaud and Victor Kahn, does an outstanding job of detailing some important and basic checkmate patterns.

thanks again. I have the book "Improve Your Chess Now"
