Kinetic Patterns in Reactive chess is a very interesting chess book written about the intuitive command of repeated kinetic patterns.
Going throw this book will help you develop a kinetics based algorithm for identifying and understanding chess patterns.
Personal I think that players as Magnus Carlsen have a natural born talent for chess patters.
In ChessBase we could read: If ‘pattern’ is understood as ‘piece configuration’, acquisition of chess skills appears even more cumbersome, depending on how fast one
can set up different positions either on a board or on a computer screen. On average, with 10 learned a day, it takes 27 years to acquire 100,000 patterns which, in turn, makes
it hard to explain how young super-GMs, like Magnus Carlsen (GM at 13, learning chess at age 8, means 20,000 patterns a year and 55 patterns a day), at such a tender age can be much stronger than older GMs having had much more time to acquire far more patterns. Or, are we talking about different GMs being familiar with different sets of patterns reflected in the rating differences? Rune Vik-Hansen.
Our author claims that shot puzzles with kinetic info are easier to remember than without,and that makes a lot of sense.
This and more are more than excellent explained by the brilliant chess philosopher & software engineer Gene Milener,who wrote in 2006 the best selling work Play Stronger Chess by Examing Chess 960.
Fascinating to mention is chapter 24 with the subject Under whelmed by Over learning, Gene Milener discusses here the works from several other chess contributions as from,
Adriaan de Groot,who tested in the past chess positions on very strong players as Paul Keres and Alekander Alekhine!
For training,J.R Capablanca suggested that students start by studying the endgame phase,before proceeding to the middle game.Most chess mastters advise the class player to analyze master games,and his own games too.
Michael de La Maza wrote that his trainer advised him to study some openings in depth.
De La Maza soon discared the advice and the trainer,and recommends a devotion to shot puzzle training.
By the way Gene Milener,his references to other works in this book is more than impressive!
Some players claim that memorizing of whole chess games help you to internalise useful patterns for the long term but our author does not agree, simple try this book and I can insure you, that your play will improve!
Conclusion:This is super reading!
