[1] gives all the information I have, which includes the games. The tournament was played in the RAI-building, with Piet Bakker as the chief arbiter. Boey did not do as well as the previous year and ended on a disappointing shared 8th place. Schumacher played in the reserves section, where the final standings were as follows:
Reserves A: 1-2.Van Wijgerden & Boersma 7½ 3.De Graaff 5½ 4.Matzner 5 5-6.Witt & Holscher 4½ 7.Marcus 3½ 8.Ghijsen 3 9-10.Schumacher & Brinkers 2
