On Saturday, Julian Assange posted on his Twitter account a picture of a chessboard, showing a famous chess position, without accompanying it with any text.
The move is actually from the famous game in 1918 between then-reigning US champion Frank Marshall and his Cuban rival, José Raúl Capablanca.
Marshall spent years planning an attack against Capablanca, who is represented on the chessboard by white pieces. However, the Cuban player managed to repel the attack and won the game.
Speculation has arisen on Twitter as to which color represents the whistleblower, and what he was trying to say with this cryptic message.
One user suggested that the position showed on the picture may indicate that Assange has left the Ecuadorian embassy in London, where has been staying since 2012 since being granted political asylum.
Earlier in the week, the Ecuadorian Foreign Ministry confirmed granting naturalization to Assange. At the same time, the British Foreign Office has dismissed a request from the Ecuadorian government to grant Assange diplomatic status.

Another interpretation was that for Assange the game is not over yet, but he "is in a strong position" to counter US efforts.
Other users pointed out that the position shown in Assange’s post suggests that three moves are needed to checkmate, raising another batch of theories about what this message may be about.
Since the beginning of the year, Assange has posted only three tweets, all of which are enigmatic, and have sparked a frenzy on social media.
