Unfortunately, the Corona pandemic put a stop to almost all live tournaments, and in 2021 the third edition of the International Open of the Club Caissa Guatemala went online as a 7 round Swiss tournament with a time control of 15 + 10, played on chess.com.
But the tournament was just as strong as the previous editions. 96 players from 19 countries took part. Among them were 13 grandmasters, including stars such as Lázaro Bruzon, Eduardo Iturrizaga, Cuban champion Carlos Albornoz, and many more.
Dutch GM Roeland Pruijssers (2561) won the event with 6.5/7. Second place went to the German GM Ilja Zaragatski (2522) with 6.0/7, while GM Sandro Mareco (2629) came in third with 5.5/7 and the best tie-break.
