Vernon Neppe, MD, PhD, FRSSAf, is a neuropsychiatrist based in Seattle. Here he provides a detailed analysis of a chess match played between a living grandmaster, Victor Korchnoi, and an ostensible deceased grandmaster, Géza Maróczy, whose moves were communicated through a spiritualist medium using automatic writing. Neppe argues that this is a strong case supporting the hypothesis of survival of consciousness after death. It combines an unusual degree of accurate information with a high level of chess skill, plus aspects of personality.
