I believe that the examples in this book are of very high value for both elite and aspiring chess players - even in the 21st century, a time of computer analysis and evaluation. The works themselves come from the highest level of tournament play, and many of the examples have an “etude” feel to them, where the solutions are often quite nonstandard, yet entirely practical from a critical over the board situation. The book before you engages the reader in useful calculations all the while expanding the player’s perception and confidence in a phase of the game where computer theory and preparation are of little value. ~ Alexander Hart (translator)
