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 schedule after 38 years in the business. He mainly works local shows for smaller promotions.
