The Dutch city of Rotterdam hosted a four-man vierkamp tournament in December of 1931. Among the participants were Edgar Colle of Belgium, Salo Landau of the Netherlands, Akiba Rubinstein of Poland, and Savielly Tartakower of France. The chess masters played double rounds (vierkamp) in what was a surprising upset of expectations. Landau, originally from Poland until his family resettled him in Rotterdam, finished clear first with wins against every other opponent. It was his first notable tournament victory and he would go on to be Dutch champion five years later. This proved to be one of Colle's last best performances in an international event since he would die from complications involving surgery five months later. Tartakower and Rubinstein both finished in the bottom of the standings which must have been surprising to the majority of spectators who were used to their exemplary chess play.
