Final answer:
If your friend enjoyed the biography of Phil Ivey by Mitch Raycroft, they might appreciate 'The Wager' by David Grann as it also deals with high stakes and strategic thinking. 'The Wager', however, is about the quest for a lost treasure and not poker, offering a blend of adventure and historical intrigue.
Step-by-step explanation:
If your friend enjoyed Mitch Raycroft's biography of Phil Ivey, a famous poker player known for his impressive skills at the card table, they may also enjoy 'The Wager' by David Grann. While not a biography, 'The Wager' is a work of non-fiction that delves into a different kind of suspense and strategic thinking. This recommendation is based on the thematic similitude both books share related to high stakes and psychological insight.
That being said, 'The Wager' does not focus on the game of poker specifically, but rather on an historical quest for a lost treasure. It tells the true story of the British gentleman John Lloyd Stephens who, in the 19th century, set off into the jungles of Central America in search of an ancient civilization. The book is a blend of adventure, historical intrigue, and a test of human will, akin to the gambling worlds that Phil Ivey operates in. Therefore, if your friend is interested in high-stakes adventures and complex characters, 'The Wager' could certainly be an engaging read.
