Branson is well-known for his adventurous side, and you’ve likely seen many a photo of the Virgin Group founder kitesurfing and hanging out on the high seas. But perhaps his favorite hobby is far more of a mental activity. “I think chess may just be the best game in the world,” he writes on Virgin’s blog. “It combines the greatest aspects of many different sports — tactics, planning, bravery, and risk-taking — plus you can have a cup of tea and often a stimulating conversation while you play!” Branson says he’s likely played thousands of games in his lifetime, and he tells The Telegraph afternoons on Necker Island are always spent on the beach, oftentimes playing chess with his kids.
