On the 50th anniversary of Groningen (1946), the surviving players (Christoffel, Denker, Guimard, Najdorf, Smyslov, Szabo and Yanofsky) met in Groningen for a reunion tournament, the Staunton memorial 1996.

"It was not practicable to stage a five-round all-play-all tournament, but three rounds were played." ('Najdorf: Life and Games' by Tomasz Lissowski, Adrian Mikhalchischin, Miguel Najdorf; p 253.)

There are only a few games in the database. I've uploaded the missing ones: Najdorf vs Guimard, Szabo vs Najdorf, Smyslov vs Guimard, Guimard vs Christoffel, Denker vs Yanofsky and Yanofsky vs Szabo, and await their appearance.

Hebert Pérez García has uploaded his memories of this event to youtube (commentary and interviews in Spanish):
