Miguel Quinteros

From Wikipedia, the free encyclopedia

Miguel Quinteros (born December 28, 1947 in Buenos Aires) is an Argentine chess grandmaster.

He won the Argentine Chess Championship at the age of 18 and in 1969 took 8th at the Mar del Plata Zonal tournament (zt). In 1972, he tied for 2nd-3rd at the São Paulo zt, earning him a place at the Interzonal tournament in Leningrad the following year and finishing 11th-12th. In 1975, he took 2nd at the Fortaleza zt and qualified for the 1976 Manila Interzonal, where he could manage only 14th place. He is married to a former model from the Philippines who he met at the Manila Interzonal. He won at Moron 1982, took 2nd at New York 1983, and won at Netanya 1983.

Quinteros played for Argentina six times in the Chess Olympiads of 1970, 1974, 1976, 1980, 1982 and 1984. He won an individual silver medal for his third board performance at Haifa in 1976.

In 1987, he was barred from playing in FIDE events for three years because he played in South Africa, a FIDE-sanctioned country. Quinteros was the first grandmaster to visit South Africa since 1981 and he gave simultaneous exhibitions in Cape Town, Sun City and Johannesburg.

Quinteros was awarded the International Master (IM) title in 1970, and the GM title in 1973.

Quinteros has a variation in the Sicilian defence named after him (1.e4 c5 2.Nf3 Qc7).
