• We provide clocks and set it up for players.

  Time controls tell you how much time you have for each game.
  G90+30 means game in 90 minutes with a 30-second increment with each move. This means you get 90 minutes, your opponent gets 90 minutes, and with each move players get 30 seconds added to their clock.
