Starting with the very first Russian AI Cup championship, the information about the names of the game participants was available to user strategy. In fact, when a boxer or a chess player preparing for a match, he studying his opponent in addition to general training. The participants of this championship also have such possibility. If someone has implemented efficient, but inflexible strategy, you can always take this into account and predict the behavior of such artificial intelligence by its name. Everything worked properly… up to some time.
The recent integration of accounts with the IT.Mail.Ru portal, among other things, added unexpected ability to change the username before an important stage of the competition and thereby confuse other strategies. Despite the fact that formally the use of such possibility is not prohibited, we consider it unsportsmanlike conduct. Therefore, the possibility to change your login will be frozen the day before the start of the Finals and recovered during the day after.
Of course, we will not ignore the opinion of the community and will remove the information about the user name from the API in the next year. However, this time the Finals will be played the way it’s meant to be played.
