Villahermosa (‘Beautiful village’) is the capital of the Mexican state of Tabasco, located in the southeast of the country. Known as ‘The Emerald of the Southeast’, the city is rich in natural resources and an important business centre for the Mexican oil industry.

Despite the difficulties related to the sanitary crisis, the Mexican Chess Federation managed to organize the 66th edition of the ‘Campeonato Nacional e Internacional Abierto Mexicano’, which consisted of seven concurrent tournaments, including an International Open, a Women’s Tournament and a Seniors Tournament.

The highest-rated player in the main event, Jorge Cori from Peru, won the main event after scoring 7½/8 points in the 5-day open tournament. Cori’s single draw came in the last round, when he faced second seed Sandro Mareco (Argentina) with the black pieces. Mareco finished in sole second place despite losing his third-round game against Mexican FM Javier Benítez, rated 342 points lower than him.

Cuban GM Juan Carlos Obregón scored as many points as Mareco (6½/8), but finished third on tiebreak criteria. Third seed Cristóbal Henríquez from Chile finished on 6/8 after losing both to Cori and to Mareco — he played with the black pieces against both top seeds.
