diagonal: Liechtenstein had been host for thousands of chess players from over 50 countries all over the world through these years. The Liechtenstein Open Tournament in the Middle of Europe started its history in 1983 with 56 participants and a brilliant victory of Viktor Korchnoi (8.5/9), who won next year as well (two entries, two clear wins). Zenon Franco won in 1986.
The last edition in Triesen in 2014 was won by Sebastian Bogner, then Germany, ahead of renowned Pete Doggers <Mr. ChessVibes, today Mr. Chess> who was walking around in Liechtenstein with a smile on the face, achieving an IM norm: https://www.chess.com/blog/PeterDog...
Nona Gaprindashvili won the separate Senior Open that year, ahead of a bunch of male contestants :)
A cozy little tournament, a pity it does no longer exist. The Open Festival was an inherent part in the agenda of many chess globetrotters (for instance GM Farago or GM Rozentalis).
The number of participants reached nearly 200 players in its best years, mostly between 100 and 150 attending chess players p.a., with several FIDE titulars.
The 33rd FL-Open was announced for 2015, but did not take part due to financial and organisational issues (it became a personal war behind the scenes in the Federation). An edition for 2016 had been planned vaguely, but the series has collapsed now.
Another game from the very first Liechtenstein Open, then held in Mauren:
