Grandmaster Lothar Vogt
stayed in summer 1990 in the Hotel Holiday
in Thun, giving a simultaneous demonstration.
He was playing
against 40 Chess enthusiasts from the Bernese
Oberland.
On the picture he gave me his autograph.
Two hours later, he had to resign against me.
Also Hermann Linder, sitting on the left of
me,
defeated the Grandmaster.
