Grandmaster Boris Gelfand won the European Junior Championship in 1987 and reached No. 3 in the World in 1990. He has led the Israeli team to numerous medals at both European and Olympiad level. Gelfand won the 2009 World Cup and has participated in six Candidates cycles, winning it in 2011. He lost the 2012 World Championship match in the play-off. At 46 he is still winning tournaments ahead of the best players in the world, in many cases men half his own age.

"This is a book about doubt, about guessing at decisions, about calculating and seeing a lot but still missing things and how that all works out in practical games at the highest level.In conclusion, this is a book that speaks to your practical soul… it's an invaluable opportunity to compare your thinking process to the way a top grandmaster takes difficult decisions." -- GM Matthew Sadler, New in Chess
