A collection of 140 recorded games labelled Muenster op in 1991. The historical field, winner, official standings, exact dates and total number of games actually played are unestablished.
This collection preserves 140 games recorded under the Muenster Open label in 1991. The scores contain 114 observed player names and round labels from one to nine.
The surviving collection
The complete historical field, winner and official standings remain unestablished, so these records are presented without a competitive table. A retrospective organizer history places the Münsterland Open in Stadthalle Hiltrup during 1991–93; it does not supply a full record of the 1991 event.
Dates and a short score
Most records give only the year. One round-seven score is dated 24 October, which is preserved without deriving full tournament dates. One legal three-ply White win survives; its physical-play status and full played length remain unknown.
