The Bobby Fischer biopic Pawn Sacrifice implies that a brilliant mind obsessed with chess is at risk for madness: the threat is that closed system of logic with a massive amount of possibilities can bring you close to some kind of edge of sanity, a rabbit hole towards a maddening peak at the true vastness of the universe. Peter Sarsgaard’s Fr. William Lombardy ominously predicts Bobby’s unraveling by recounting a story about 19th century American chess legend Paul Morphy, who also had a short and illustrious chess career followed by a life of personal failures and mental illness. But, while Bobby Fischer’s antics were highly documented, extreme and political, Paul Morphy’s supposed madness is a bit more of a myth grown larger in the shadow of Bobby Fischer’s rocky life.
