Jaap van Oosterwijk Bruyn in the 1985 tournament report ^[1]:

The game of Schaak vs. Chess 0.5X was the shortest game of the tournament.

[Date "1985.10.??"]
[Round "6"]

exd4+ 16.Kxd4 O-O-O+ 17.Kc3 Qf3# 0-1

The author of Schaak, Alex van Tiggelen, one of the newcomers, was eager to show that this fast defeat was due to a freak and challenged Chess 0.5X to a second game. To his dismay this game was even shorter than the first one.
