First seen Jun 14, 2026 · Last updated Jun 14, 2026
Summary
This study looks at whether drinking caffeinated coffee helps professional chess players think faster and make better moves during tournament games. Twelve top-level players (rated 2300-2600 Elo) will play chess after drinking either regular coffee or decaf, without knowing which they got. Researchers will measure their accuracy, reaction time, and puzzle-solving skills to see if caffeine gives them an edge.
