sneaky pete: <sp147> Saturday October 10; Sunday Oct 11; Tuesday Oct 13; Wednesday Oct 14; Friday Oct 16; Saturday Oct 17 and Sunday Oct 18. Playing hours were from 7 till 12 pm (some of the Dutch players may have had day jobs) with an adjournment after at least 40 moves if necessary. Monday and Thursday were rest days for the lucky ones with no adjourned games.Most games were played in 2 locations in Amsterdam, but round 4 (October 14) was staged in "The Zoo", Den Haag and round 6 (October 17) in Hotel Bristol, Rotterdam.
The round 1 one Van den Bosch vs Van Scheltinga was played on the first rest day (Monday 12) and the round 2 games Van Scheltinga vs Fine and Van den Bosch vs Landau on the second one (Thursday 15).
Prins had beaten Van den Bosch in round 1, "then the latter named (...) withdrew through indisposition and T.D. van Scheltinga came in to take his place, with such a score as he had. But Prins questioned the justice of some competitor having to meet a weaker player than the original starter, and withdrew; whereon Van den Bosch, now recovered, came back to the tournament, to make up the 8." Text in "..." from the introduction to the Chess Digest edition of Fine's book, quoted from the British Chess Magazine.
I suppose you already knew that the tournament was organised and sponsored by publishing company De Arbeiderspers (The Workers Press) and its newspaper Het Volk (The People), and that less than a year later, on September 1, 1937, Reuben Fine married miss Elisabeth Keesing, a journalist of the organising paper Het Volk. But maybe you didn't know that the marriage was written up on the front page of said newspaper under the heading <Queen's Gambit Accepted>?
I'll check my sources some more, to see if I can find any info about the dance contest on the second rest day.
