Jan Markos is a Slovakian grandmaster and trainer. His previous book, Under the Surface, was the English Chess Federation's 2018 Book of the Year.David Navara is a ten-time Czech Champion and a world-class grandmaster. He is noted for combining fighting spirit with outstanding sportsmanship.

"I learnt – sometimes rediscovered – many great practical tips from this quirky and original book. One I really liked in particular was Navara's comment when asked to what extent it is possible to employ tailor-made preparation against a specific opponent. Navara replies that 'A player who is familiar with many openings and is comfortable in all kinds of positions will be able to apply targeted preparation for an opponent much more efficiently than someone with a narrower repertoire.' Versatility and psychology go hand in hand in chess. If you want to use psychology, improve the versatility of your own style first. For me, that's the best thing that's ever been said about this subject!For the rest, a really interesting and original work, just like Markos previous book, Under the Surface! 4 stars!" -- GM Matthew Sadler, New in Chess
