EP 439 — Samuel Sonning (Founder of NoctieAI): The Instructive Value of Memorizing Games, the Benefit of Losing Rating Points, and a Deep Dive on Chess and AI

50 minutes

This week’s guest is Samuel Sonning, a Swedish computer scientist, former Google engineer, and founder of NoctieAI—a user-friendly chess platform featuring rating tests and bots designed to play like humans. In our conversation, Samuel discusses his unique improvement philosophy as an adult learner, including how memorizing famous games helped him build intuition and visualization skills. A passionate player himself, many of Sam’s ideas have directly shaped NoctieAI, which offers immediate move feedback and personalized flashcards based on individual mistakes. We also explore the broader state of machine learning as it relates to chess. Samuel has been fascinated by this intersection since the days of Kasparov vs. Deep Blue, but while he still sees great potential in AI-assisted chess learning, he no longer views chess as the leading edge of AI development. This was a fascinating conversation, and I’m excited to follow NoctieAI’s continued evolution.
