    Time controls tell you how much time you have for each game.
    G60;+5 means game in 60 minutes with a 5-second added with each move. This means you get 60 minutes, your opponent gets 60 minutes, and at each move there is a 5 second added to the players' time.
  • How many games/rounds?
    This is a round-robin tournament. Every player in each quad will play against all the other players in the quad for a total of 3 games.
