Armstrong Cup

The Armstrong Cup is the oldest Irish team league competition and has been played every year since 1888, perhaps giving it a claim on the longest running chess competition in the world. The Club is named after William Armstrong BL (1849-1899) who presented the cup in its first season It is organised by the Leinster Chess Union and is division one of the Leinster leagues. Each team comprises 8 players, and the league comprises 12 teams. Each year the bottom two clubs are relegated, and the top two clubs from the second division Heidenfeld Trophy are promoted. As well as being graded by the ICU, games in the Armstrong Cup are submitted for rating by the International Chess Federation FIDE.

In 1971 the League was divided into top 6 teams who played each other home and away, the remaining teams formed the new division two named the Heidenfeld Trophy with the older Ennis Shield league competition becoming the third division of the Leinster leagues. In the early 1980s the LCU experimented with having a preliminary round and then dividing the league into 2 section however it returned to the league format.
