Carlos Torre Repetto Tournament in Mexico
By Seppe De Vreesse Pieters and I.M. Oscar Gerardo Sánchez Enriquez
Introduction
From December 15th till the 20th, the 28th edition of the Carlos Torre Repetto Tournament, took place with a total of 497 players competing in six different categories. The main event was an open section for players with a +2000 rating and there were also 5 side events: a second category group for those rated between 1500 and 2000; a third category for beginners rated under 1500; and finally, three youth sections (-12, -10, -8).
The location
The tournament is played every year in Mérida, the capital of the state of Yucatán, in the southeast of Mexico. The city offers a lot to its visitors: good weather, great food, it is close to the beach and to several archeological sites of the ancient Maya culture. If you want to know more, check out the pictures that Alina L’Ami took last year: “Snowless Winter 1” and “Snowless Winter 2”

The main event (“categoría magistral”)
In the open +2000 section 148 players from 21 different countries competed. 102 of them have an official Fide title (amongst others: 20 GMs, 5 WGMs, 25 IMs and 11 WIMs).

The beautiful playing site: the “Hall of history” (Sala de Historia) of the House of Government
(Palacio de Gobierno) of the State of Yucatán. The walls are decorated with
mural paintings that tell the history of Yucatán.
Significant was the participation of 38 cuban chess players (Bruzón, Quesada, Ortiz, Gómez Garrido, amongst others) and the presence of a few “teams”. Peru sent the complete the Olympic team from Baku (Córdova, Cori, Cruz, Vera,…) and also members of several US university teams like Texas Tech (Baryshpolets, Grover, Gorovets, Vorontsov, Torres Rosas, Andrenko, Muñoz led by their player-captain GM Alexander Onischuk), Saint Louis (Swiercz, Rambaldi, Ali Miranda) and Webster University (Shimanov, Durarbayli) played.
The presence of a lot of strong American players was due to the excellent management of tournament director Javier Alberto Herrera Aussin, the Patronage of Carlos Torre Repetto and the local authorities of the state of Yucatán.

The number one rated player, Alexander Onischuk with local authorities, at
the official opening of the tournament on Friday, December 16th.
There were several pretournament favorites with Alexander Onischuk as a former US champion; Dariusz Swiercz, recent winner of the Millionaire chess tournament; Emilio Córdova and Jorge Cori of Perú; Lázaro Bruzón and Yuniesky Quesada from Cuba; Aleksandr Shimanov from Russia and Vasif Durarbayli, as well as a bunch of outsiders (Andrey Gorovets from Ukraine, Francesco Rambaldi from Italy, local hero Juan Carlos González).
Nevertheless, it was once again Lázaro Bruzón who showed his might again winning two crucial encounters on the white side in rounds 7 and 8: first he beat Rambaldi in a French Tarrasch and then he won against Swiercz after a crucial mistake of the black side in a Catalan opening.
Aleksandr Shimanov tried his best with the white pieces in a sharp battle in the last round against Bruzón, who lead by half a point. It wasn´t to be: black saved the draw playing a crucial sequence of forced moves: Qh3 and Kg6! allowing Rc2 (see below in the annotated games). Bruzón was victorious again in the overall standings.

one of the decisive games of the tournament.
