In 1974 Álvarez ' long time friend and trainer " El Enfermero " gave him permission to use his name and Álvarez began working as " El Enfermero , Jr .

Originally Álvarez was scheduled for a title match on the night and Solar II was booked in an " Apuesta " match against another wrestler , when Solar II ' s opponent did not show Álvarez was asked to lose the match to Solar II . After losing the mask Álvarez lifted his mask to show his face , but in a break with Lucha Libre tradition did not remove the mask in front of the audience . Álvarez kept working as " Enfermero , Jr . " until 1988 where he adopted the ring persona he is most known as " Jaque Mate " The " Jaque Mate " persona was inspired by the 1920s and 1930s Chicago Gangster scene , complete with black suit and fedora hat , in addition to a black mask with white chess pieces on it . In 1990 Jaque Mate teamed up with Pierroth , Jr . and Masakre to form " Los Intocables " ( Spanish for " The Untouchables " ) , with both Pierroth , Jr . and Masakre adopting the same type of " Gangster " ring wear Jaque Mate used . The team worked a heated storyline feud with " Los Infernales " ( MS - 1 , Pirata Morgan and Satánico ) , a group Masakre left to form " Los Intocables " , the feud saw " Los Incotables " win the CMLL World Trios Championship from " Los Infernales " on March 22 , 1992 . The team held the belts for approximately six months before " Los Infernales " regained them . In March 1993 Jaque Mate and Masakre entered a tournament for the vacant CMLL World Tag Team Championship . They defeated Kahoz and Gran Markus , Jr . in the first round but lost to Vampiro and Pierroth , Jr . in the second round . On March 25 , 1993 Jaque Mate defeated Apolo Dantés to win the NWA World Light Heavyweight Championship . Over the next 20 months Jaque Mate would defend the title ten times , against opponents such as Pirata Morgan , El Dandy , Ringo Mendoza , Silver King and Blue Demon , Jr . before losing the title to El Dandy on December 4 , 1994 . When Sangre Chicana left CMLL to join CMLL ' s rival promotion Asistencia Asesoría y Administración ( AAA ) , Álvarez decided to join him , continuing an ongoing feud between the two . His feud with Sangre Chicana was put on hold as Jaque Mate began working with Octagón . The two were on opposite sides in a tag team Steel cage match where the last man in the cage would either be unmasked or shaved . In the end neither Octagón nor Jaque Mate were involved in the finish , having both fallen off the cage to safety while fighting each other , in the end Heavy Metal defeated Kick Boxer , forcing him to unmask Three months later Jaque Mate and Octagón squared off in a " Luchas de Apuestas " match , which was the main event of the 1999 " Guerra de Titanes " . Jaque Mate lost to Octagón and was forced to unmask for the third time in his career . According to Álvarez he was paid " a substantial sum of money " to lose his mask to Octagón that night . After losing his mask to Octagón Jaque Mate resumed his feud with Sangre Chicana , losing a " Luchas de Apuesta " match that saw him shaved bald . Álvarez does not wrestle full - time , working a lighter scheduled after 38 years in the business . He mainly works local shows for smaller promotions .
