Thematic tournaments
Thematic tournaments are made up of thematic games which start from a pre-defined starting position, such as three moves into a King's Gambit opening. This allows players to play similar games and test each other in certain openings.
These tournaments are marked with a 'Set Position' icon on the tournament page, and the tournament title usually indicates the starting position of the games.
