A TACTICAL SHOT

In the Chess King's rapid game Micromaster - Sudav (11 July 2026), I had white pieces and a lost position. Black had two extra pawns.

Suddenly, Black made a naturally looking move 27...Ra8-b8??

See the diagram below:

White to move

Do not mess with me. Black has a weak back rank and his King has no vent-hole. White has the open e-file and a pawn on the 6-th rank. And White has an intermediate move...

The analysis of the game can be seen below:

BLOCKED PLAYERS LIST OF THE CHESS KING

The blocked players list of the Chess King's Playing Hall:

1. Allows seeing the challenges despite the block;
2. It is also not really private. 

It is a major flaw.

If I do not want to play with someone, I shall block that player. However, I do not want to declare it publicly.

Currently, I see the challenges of those I have blocked and also those who have blocked me.

Worse, when clicking on the challenge, the player sees a message that the opponent has blocked the player.

Worse, the player is not informed beforehand that the blocked players list is not entirely private.

All this in sum makes the blocked list dysfunctional and also communicative, contributing to provocations and intrigues.

If the platform Chess King continues to maintain such weird features, I cannot regard it as a solid chess platform.

Post Scriptum

Chess King's blocked players list has the following features:

1. If you have blocked the player A, you still see A's challenges and you are even able to accept them and play again against, say, a recidivist hooligan or cheater. 
2. If the player A has blocked you, you still see A's challenges but you cannot play: instead you receive a message that A has blocked you.

Chess King's Support has the following features:

1. The Support does not support you. 
2. The Support never answer your emails.

It is difficult to follow who are these people responsible for Chess King. Finally, I managed to find out that the grandmaster Alexandra Kosteniuk is probably responsible for that disgusting mess.

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.

LICHESS IS FULL OF CHEATERS

I will stop playing on Lichess because, over the past few days, more than half of my opponents have used a chess engine (either occasionally or for the entire game), and Lichess seems unable to do anything about it.

PS

Then, I tried to play again on the FIDE Online Arena. As they announced, they had given me back some rating points I had lost against the cheaters.

It is nonsense. They gave me back the rating points of one or two games, while there have been tens of reported cheaters.

Moreover, they have awarded grandmaster titles (AGM) to some of these players who cheat in every game, from start to finish. They are simply mocking people.

Then I played a couple of games there, and again someone managed to make 24 very precise moves in 2 minutes, in a tactically complicated, unknown position.

I do not understand why they call it an online chess arena owned by FIDE.
