This is what some reviewers said about Daniel Naroditsky's
Mastering Positional Chess ."Is it possible that an author so young has sufficient wisdom to impart such knowledge? As far as this book goes, the answer is an unequivocal 'yes'." - Marshtower Chess Reviews"It's a very good book - exceptionally instructive, full of practical advice that every chess player needs to pay attention to in order to get better." - Pete Tamburro, Chess Life"It may well be one of the best books ever written on positional chess." - Arne Moll, ChessVibesIf you can stand more praise, please have a look
