Thessaloniki is said to be named after a half-sister of Alexander the Great. Fidé staged a recent Grand Prix there, with the surprising outcome that it was won by the Cuban grandmaster Lenier Dominguez Perez with 8/11, ahead of such luminaries as Gata Kamsky and Fabiano Caruana on 7½ as well as Hikaru Nakamura, Veselin Topalov, Peter Svidler, Alexander Morozevich and Vasyl Ivanchuk.
Dominguez was given a boost when Ivanchuk failed to convert a winning position in an early round. The blow to Ivanchuk’s morale sent him into a tailspin into last place with just 3½/11.
