Good evening, everyone. I'm a bit shocked because I played with a cheater in a team tournament, and I had suspicions, but now this situation has escalated to the point where my team won't play against a team that cheats. Report them immediately to the organizer of the team tournament. Also, after watching the cheater's replays for a few turns, I was surprised by how easily he defeated Go in the early stages of the second week, even with two interruptions (due to a message about a neighbor's repair), and then confirmed the report. Now I feel bad. I ask that measures be taken to prevent this from happening to other players in the future. Thank you.
