  Probably a fisherman or something. However, Bobby Fischer is one of the best chess players of all time. Objectively speaking (by rating and accuracy compared to modern chess computers), the best Grandmasters in the world today are better at chess (Magnus Carlsen, Hikaru Nakamura, Ding Liren etc.), but this is because they have stood on the shoulders of chess giants who have come before them. The same holds true when comparing Fischer to chess players before his time such as Paul Morphy or Jose Raul Capablanca.

Bobby Fischer played Najdorf Sicilian, and King's Indian Defence as black and Ruy Lopez as white.
