The tournament was divided into two sections: the Championship Tournament and the Masters' Tournament. The first section was for players who had won an international tournament. The Championship Tournament took place in the Casino of Ostend from 16 May to 14 June 1907. Dawid Janowski, Siegbert Tarrasch, Carl Schlechter, and Frank Marshall accepted the invitation, while Emanuel Lasker and Géza Maróczy declined and were replaced by Amos Burn and Mikhail Chigorin.
