Yuri González beats the field
From the 21st to the 26th of March 2019, the “Festival de Ajedrez de San Juan” took place in Puerto Rico’s capital. The festival was organised by the Autonomous Municipality of San Juan and the capital’s Department of Sports and Recreation. This was, without a doubt, the biggest chess event to take place in Puerto Rico during the last 30 years.
The meeting was organised at the San Juan Natatorium and was headed by Gabriel Pinales Roussel, President of the San Juan Chess Club. On Thursday morning, Gabriel and his great staff kicked off the festival with the Metropolitan Championships for age groups spanning from U-8 to U-18 — both for boys and girls — with 108 young players participating.

Organiser Gabriel Pinales just trapped that bishop
On Thursday afternoon, the main section of the "VIII Memorial Hermanos Colón Romero" — in memory of Miguel and Arturo Colón Romero — began. Four special guests led the field, two from Cuba and two from the United States. From the Caribbean Island arrived GMs Yuri González Vidal and Reynaldo Vera González, while from the US former national champions Alex Yermolinsky and Alexander Shabalov made their way down to San Juan. The highest rated Puerto Rican player was national champion Edgardo Almedina.
It was a seven-round Swiss, which lasted four days. There were many surprises, so it was never clear who would win the event. In the end, nonetheless, rating favourite Yuri González took first place after scoring an undefeated 6 out of 7. Second place went to Alex Yermolinksy, a half point behind, while Puerto Rican champion Edgardo Almedina tied on 5 points with 2022-rated Diego Zilleruelo, who upset GMs Reynaldo Vera and Alexander Shabalov. Reynaldo Vera and Juan Dávila also finished on 5/7.

Analysis by Alex Yermolinsky
Yermo has been travelling around Latin America with his good friend Alexander Shabalov. He has been to Chihuahua (Mexico) and Arica (Chile), for instance, and always sends us something from his trips. This time around, he analysed the two games in which tournament sensation Diego Zilleruelo upset experienced, much higher-rated grandmasters.

Side events
The celebration did not finish on Sunday, as all four grandmasters were booked to give lectures on the following two days. On Monday, Reynaldo Vera talked about "Capablanca's universal dimension". The following day, Alexander Shabalov gave a lecture called "Ignoring the threat", Alex Yermolinsky talked about "Bishops of opposite colours" and Yuri González gave a presentation on "How to face 1.e4 with Black: Ruy López structures".
Master Class Vol.4: José Raúl Capablanca

He was a child prodigy and he is surrounded by legends. In his best times he was considered to be unbeatable and by many he was reckoned to be the greatest chess talent of all time: Jose Raul Capablanca, born 1888 in Havana.

Cuban Reynaldo Vera lecturing about Capablanca
Two five-round Swiss tournaments were played for the U-1900 and U-1600 categories. Javier Ríos Maldonado and Abner Silva Rodríguez were the winners. Finally, a blitz tournament wrapped up the festival. Once again, Yuri González took first place after scoring 8 out of 9, and was followed by Reynaldo Vera and Alex Yermolinksy, who collected 7 points each.
Full results: B group (U-1900), C group (U-1600) and Blitz
