Tal plays chess while dying
Mikhail Tal, world champion in 1960, spent much of his life seriously ill with kidney disease, surgeries and painkiller dependence. He still smoked, drank and played constantly. Weeks before his death in 1992 he left a Moscow hospital to play in a blitz tournament and beat Garry Kasparov in one of the games, showing that his play came from appetite for the game rather than from managing his career.
