Cuban IM Diasmany Otero shocked the favorites and took the first place at the LIX National and International Mexican Championship Puebla 2013, which was held on 26-31 March at the Complejo Cultural Universitario de la Benemérita Universidad de Puebla.
Otero, who lost in the eighth round against top seed Alexander Onischuk, finished with a nice win against countryman Aramis Alvarez to get 7.5/9 points.
The Cuban surprisingly defeated strong players such as Bartlomiej Macieja (2630) and local hope Jose Gonzalez (2517).
American Grandmasters Alejandro Ramirez and Alexander Onischuk also finished with 7.5 points, but had worse tiebreak scores.
Ramirez beat the local Alfonso Almeida in the last round, while Onischuk had to settle for a draw against Peruvian GM Emilio Cordova, who arrived fourth in the standings.
