Final answer:
While 'The Wager' by David Grann is not about poker or gambling, it could still interest someone who enjoyed Phil Ivey's biography if they appreciate narratives exploring human ambition and exploration.
Step-by-step explanation:
If your friend enjoyed reading a biography about Phil Ivey, a renowned poker player, then 'The Wager' by David Grann might indeed be a fascinating read. David Grann's 'The Wager' is a tale that, like a biography, involves elements of adventure and a deep dive into a character's life and pursuits. Nonetheless, it is important to note that this book is not about poker or gambling, but about the historic search for the lost city of El Dorado. If your friend's interest in biographies is mainly centered on poker, gambling, or the personal stories behind high-stakes players, they may wish to explore other titles more specifically related to those subjects. However, if they appreciate well-researched narratives that explore the depths of human ambition and exploration, 'The Wager' could be an excellent recommendation.
