Meet Marc Barthelemy, a physicist at Paris-Saclay University in France, who's shaken up the way we look at chess. Instead of just focusing on algorithms and AI, he's treating chess like a complex system. In a recent paper for Physical Review E, he created a special metric to predict those game-changing moments, or "tipping points, " that can totally shift the match.

Barthelemy wasn't the first to think about chess scientifically. Back in the 1920s, chess master Richard Reti tried to develop a scientific understanding of the game. He collected data and made up rules based on that data, but his work got overshadowed by advances in computer science.

What makes chess so interesting to scientists is its simple rules and deep strategies. It's perfect for testing algorithms in AI and machine learning. Barthelemy, whose background is in statistical physics and the science of cities, noticed that these studies missed something big: certain moves can really change the course of the game. He compares it to a phase transition in physics.

Thanks to online chess platforms, there's now a ton of data to analyze. Researchers have looked at things like power-law distributions, response times in rapid chess, and long-range memory effects in game sequences. But Barthelemy's work is unique because it focuses on these critical turning points that can make or break a match.
