2021 Eastern Youth Open

Sunday, February 21, 2021. Online: AGA Tournament Room on KGS

What is the Eastern Youth Open?

The Eastern Youth Open (EYO) is a 4-round open youth tournament hosted by the New York Go Association (NYGA) for all young players at all levels. Starting in 2019, the EYO provides easy access to high standard formal tournaments. Due to the pandemic, players will meet each other virtually.  

Eligibility: All of the participants must be under 18 years old by the date of the tournament. There is no rank requirement to enter. Players with no rank may register as 25 kyu. All players must be current AGA, CGA, or MGA members. Players whose ranks at their associations are out of date, but have a solid KGS rank with at least 10 most recent games may enter. Pre-registration is required.

Note: Higher divisions will carry higher prizes. All the participants must at least register at their most recent rank. Players may register in a higher rank to challenge themselves. Sandbagging activity is strictly prohibited. The tournament director holds the right to ban players who register false information.

Non-refundable Commitment Fee: $15. The commitment fee will go to the administration, referee, and the anti-AI technical team in order to cover the costs to run and analyze selected games. We intend to provide the best tournament experience to all of our participants. The commitment fee will help the administration, referee, and Anti-AI technical team to prepare for their work in advance, and discourage forfeiting.



The top three players in all divisions receive certificates and trophies. In order to be eligible for a prize, all players must compete in all four rounds.

  • Final Standing: Final standings will be determined using the total number of wins. Tiebreakers are resolved using the Sum of Opponent’s Scores (SOS) and further by Sum of Defeated Opponent’s Scores (SODOS).

  • Punctuality: all players are expected to be on time. A player will forfeit the game if he or she is more than 15 minutes late. If you win by forfeit, please wait for the tournament director’s confirmation before leaving. Otherwise, the result is marked as a tie.

  • Result confirmation: The result of a game must be agreed upon by both players. If the game finishes normally, the winner MUST send a personal message to the TD on KGS, with the results being clearly stated.

  • Disconnection: If a player leaves without finishing a game, the opponent should report to the tournament director immediately. A disconnection that lasts 10 minutes or more will also result in a forfeit.

Anti-AI Rule: The use of AI is strictly prohibited. In the top division, every player is required to record video footage of every game to be made available upon request. The visual camera must capture (1) the full computer screen and (2) both the hands and face (sideview) of the player. If the video is not provided upon request, any decision made by the TD team will be final. We highly recommend players in all divisions to have a video record of the player. We will Golaxy (https://www.19x19.com/engine/index) and Leela Zero (https://github.com/leela-zero/leela-zero) to monitor the tournament. Top US and Canadian players, with an AI expert from Golaxy, will serve as the Arbitration Committee to make the final decision if the similarity of the entire game matches 50% or more. A similarity matching 70% or more is equivalent to professional play. The similarity matches 60% is equivalent to at least AGA 7d.

If you suspect that your opponent used AI, please complete the game as normal and report to the tournament director after the game. The tournament director may not intervene in ongoing games but may use the game records as evidence of the investigation. The tournament director could initiate an investigation with or without any reports received. If a player had been found highly suspicious, the tournament director reserves the right to dismiss the results and ban the player from the tournament. The TD team may then make the final decision based on the results of the analysis and historical game records of the player.

The registration deadline is February 14, 2021.
