From Peña Jaque to Casino la Unión
Club Ajedrez Jaime Casas was founded in Monzón in 1973 from Peña Jaque. Its first home was Casino la Unión, placing its origins in the city's civic life rather than solely in official competition.
The player remembered in the club's name belonged to an older local chess story. Born in Tamarite in 1902, Jaime Casas Cases lived in Monzón for roughly two decades and had won a candidates event before unsuccessfully challenging Spanish champion Ramón Rey Ardid; a local historical account places the club's foundation five years after his death.
Two clubs in one city
Jaime Casas should not be confused with Club Ajedrez Monzón. The Federación Aragonesa de Ajedrez lists them separately and regional competitions record them as distinct opponents, an important distinction because they share a municipality and can appear in the same coverage.
Spain's top division came to Monzón
The club's relationship with Spain's highest team division became especially local in 2016. Monzón hosted the national División de Honor championship, and Jaime Casas finished third.
The later path was not linear, but it was persistent. After eight consecutive top-flight seasons and one year away, the club won the First Division in 2024, returned to División de Honor, and retained its top-flight place in 2025; it also won the Spanish club team rapid championship in 2024.
Development through competition
Pedro Ginés provides the clearest example of the club's developmental role. In 2018, the year he became under-14 world champion, Ginés described joining Jaime Casas as a key factor; the club's technical staff added support for coaching and travel and gave him experience in all seven rounds of the Spanish team championship.
That youth pathway is also visible in Mateo Mendoza, a Spanish under-10 champion for the club who won the Aragón School Under-14 Championship in 2026. He belonged to the school directed by Mairelys Delgado, whom Monzón City Council identified as a Jaime Casas coach, while the completed 2026 regional season recorded both Jaime Casas and Jaime Casas B in different divisions.
