A contest within the tournament

In the main double round-robin these four masters finished among the middle of the fourteen-player field — Marco and Teichmann shared fifth on 14/26, while Marshall and Leonhardt were part of the group tied on 12½. This extra all-play-all among them is recorded in ChessBase's Mega2024 as a distinct event ('Ostend2'), separate from the 182-game main tournament.

On its participants and structure it has every appearance of a play-off for the minor prizes, but the narrative sources consulted for Ostend 1905 do not describe its exact purpose, so it is presented here simply as what the record preserves: a genuine six-game contest, distinct from the main event, that Marco won.
