IM Andrey Ostrovskiy joined me this week for an insightful conversation.\xa0We started off discussing the biggest news in the chess world, as Andrei gave his perspective on what Alphazero\u2019s landmark success means, and doesn't mean. We then dug into Andrey's background.\xa0Andrey talked about why he made the move from his native Ukraine to Germany a few years ago and transitioned from his family business to working as a chess professional. Andrey was also happy to share some ideas about\xa0improving one's calculation and chess-playing skills.\xa0Lastly, Andrey answered a long-festering question of mine about how players of his caliber can tell when an opening line has become obsolete.
