8. FAQ
• What do the time controls mean?
The time controls tell you how much time you have for each game.
For example, G/90+30inc means game in 90 minutes with a 90-second increment with each move. This means you get 90 minutes, your opponent gets 90 minutes, and at each move 30 seconds are added to your clock.
• How many games/rounds?
The 4SS before the time control means there are four rounds or four games a player can play in the tournament. The tournaments are never elimination, so win or lose you can stay in the tournament.
