Ricardo Calvo

Ricardo Calvo Mínguez (October 22, 1943 – September 26, 2002) was a Spanish chess player, doctor, author, reporter, and chess historian, who was awarded the title of International Master in 1973 and played for Spain at the Chess Olympiads of 1966, 1968, 1972 and 1974. He died in 2002 from esophageal cancer.

Early life
Calvo spoke fluent Spanish, German, and English. As a chess historian, Dr. Calvo set out to prove that Spain was central to the monumental changes that occurred in chess late in the fifteenth century. It is most widely believed that the increased powers of the queen and the bishop were introduced during the Renaissance in Italy; however, Calvo insisted that Spain played a major role.

Politics
Dr. Calvo was deeply involved in chess politics. In 1987, he was condemned by FIDE and declared "persona non grata" (Latin: "An unwelcome person") by a vote of 72-1, for writing a controversial article in New in Chess. The article, according to FIDE, was a "racial attack on Latin Americans". In response, Calvo wrote a letter to FIDE titled "On the Nature of FIDE Legitimacy" in which he disputed their decision: ...a ban against a chess player based on any political ideas is in itself an intellectual and juridical monstrosity...Yes, any Hitler, Stalin, Pol-Pot, Mao, Sadam or Ilyumzhinov has the right, if he wishes, to play in a chess tournament. This is the real greatness of our game, a spiritual refuge far above the dirty politics of everyday life in any country."

Ricardo Calvo vs Viktor Korchnoi
This game between Ricardo Calvo and GM Viktor Korchnoi is known as "Calvo's Salvo", and was played at the Havana Olympiad 1966: '''1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 a6 5. Bd3 Bc5 6. Nb3 Ba7 7. c4 Nc6 8. O-O Qh4?!, a dubious move by Korchnoi that will allow his queen to be targeted: 9. N1d2 Nge7 10. c5 Ne5 11. Be2 b6 12. f4 N5c6 13. Nc4 bxc5 14. g3 Qh6 15. f5 Qf6 16. fxe6 Qxe6 17. Nd6+ Kf8 18. Bc4!, now Korchnoi will lose his queen or be checkmated, so resigns: 1-0'''.
