Most likely because you were cheating, or at least playing so suspiciously that the automated systems thought you were cheating. What were you doing that game?
We must have a certain degree of mercy for those cheaters. Without their engines they probably wouldn't even know how to tie their shoes.
At the time the question was posted I didn't see any mark on their open account. Today their account is closed.
On Lichess if a player either intentionally or accidentally opens an analysis board with an engine while playing, even if it is an accident Lichess declares "cheat detected" and ends the game. I do not know whether Lishogi functions the same way.
I played with this player and lost points. I hope the points will be returned through the management, like in chesscom.
@Beniiro If a game with a cheater lies too far back in time, the system doesn't reimburse you your points. But you are lishogi's strongest player, so I imagine that it takes only a few minutes for you to get back to your old rating. I honestly look up to you, you're awesome!
@GermanPlayer Danke schön for your comment. I once have visited shogi club in Dusseldolf, and everyone is kind, so I have a great impression to German shogi community.
It is easy for Japanese player to practice shogi, but far difficult for foreign players. I'm always respectful to you all.
