I HAVE ABANDONED THE ENDGAME AI

Rating Difference

Below is my comment on Discord, Engame AI:

There is a major flaw in the rating difference system of the Endgame AI. 

I guess that it is not a computer program bug but a conceptual mistake.

The rating difference can be set for the lobby so that the player does not see challenges that do not meet the player’s criteria. 

Unfortunately, this does not apply to challenges that the player creates themselves.

Thus, if I set the rating range -300…+300, everyone with a rating of -500 can still see and accept my challenge.

It does not make much sense because if I want to avoid players with a rating difference of -500, then I do not care who made the challenge.

Moreover, when others issue a challenge, the player can see the challenger's rating in the lobby and decide whether to accept it. 

That is, the rating difference works where it is not urgently needed and does not work where it is necessary.

Usually, the rating difference or rating range is set symmetrically to both the challenges of others and the player's own challenges.

I have stopped playing on the Endgame AI, too

It has happened twice on the Endgame AI: when I achieve a rating above 1900, two players with very low ratings in a row accept my challenge and beat me, significantly reducing my rating. Remarkably, such players with very low ratings have played very-very fast and precisely, so that I have been entitled to suspect that either they used a chess engine or they were anonymous top-grandmasters. 

I cannot speculate on the conspiracy theory that such targeted attacks have been organised by the chess platform itself. 

However, the platform has a feature that the rating range the player has set does not apply to the challenges the player is doing himself, which is obviously a weird feature that increases the possibility of such manipulations. 

In the case of the FIDE Online Arena, they even dared to punish the players who “too often” cancelled the games. “Too often” cancelling the game actually meant that the player’s challenges were too often accepted by known cheaters with low ratings. 

Anyway, I have stopped playing on the Endgame AI now, too. That new platform claims to be making great innovations in online chess. However, what I see are the same mistakes I have seen on several other platforms.
