How can your rating change even if you haven’t played any games? When an earlier tournament is submitted after more recent tournaments have been rated, we go back and recalculate all tournaments starting with the newly submitted one, explains Ratings Coordinator Jonathan Bresler. This may cause some ratings to move in non-intuitive ways. If there’s a path of played games from you to at least one player from the earlier tournament, your rating will change as a result of the newly submitted tournament. This ensures that the ratings system is not held up by delayed tournament reports. You can check your current rating here where you can also check the list of rated tournaments. You can also review your own tournament history or that of other players — in the American Go Association Go Database.
