First international chess tournament after World War II. Botvinnik won, receiving 1,500 Dutch guilders and a silver cigarette box from the Queen. A tablecloth was given to the best non-prizewinner. A picture of the Martini Tower in Groningen in a silver frame was given to the last place finisher. 12,000 spectators paid for admission to the event. 21 invited players showed up but only 20 players were allowed to play. The tournament did not want to turn away any foreign player, so it was between Prins and Euwe to drop out. One of the Russian players promised to invite Prins to an international tournament if he dropped out. He agreed, but the promise was never met.
