Exposing a Cheater in Chess Variants

I found a cheater who plays gothic chess with almost 100% of the best moves at depth 20 (most of them are under 20s). That cheater played minihouse with elo<1900 players to avoid being detected and become top 1 without losing a single game. In the minihouse games I use stockfish fairy to analyze, this guy always makes the best moves with a depth of about 30 in under 20 seconds. His account name is [Removed, KL. Public accusations are not allowed in the general forms.]

I tried playing a few custom games that guy created, and didn't have a single chance of winning, especially in capybara house, a variation similar to gothic but slightly changing the unit positions and adding crazy house rules, it still plays the best moves at depth 20 within 20 seconds without knowing that humans cannot play moves at that level even if they sit for a month to analyze (compared with cazyhouse, the ability to find best move must increase exponentially). He plays the minihouse less now, and the cheater moving on to other chess variations and continues his cheating career.

If you play some games and lose to this guy, you should know that you did not lose to the best players in the world like Magnus, Hikaru, Kasparov, ... but to a cheater!

At
To use fairy stockfish to analyze the minihouse game, you can go to this page, choose "Advanced" at bottom of the page and import varriant.ini with this content:
[minihouse:crazyhouse]
maxRank = 6
maxFile = 6
startFen = 2bnrk/5p/6/6/P5/KRNB2
promotionPieceTypes = nbr
promotionRegionWhite = *6
doubleStep = f

Then in "Name" field, you could choose minihouse and analysis games.
Some of sample games that I make analysis:

How do they use stockfish in variants?

It's really amazing to see cheating in variants.

I think he has cheated but did chess.com take action for engine use in variants???

Ask him to join the Discord Server where the inventor of the game (Ed Trice) plays. Also see if he can correctly "discuss his wins" with him. Maybe he will say something stupid and you can catch him.

Thanks, Gorgon_Slayer, but I don't use Discord.

I reported him a long time ago, but nothing happened, so maybe they didn't.

I can't find any varriant games that account has played.

I think there are some players who just try using engine or make other account to check what happens and how it goes. So I am not sure that you encounter with a fake account which was uses for testing or a real account.

That is also a problem. In this instance, first, I want to analyze the games that the account has played. From there, we can determine whether or not the account is cheating.

It is still possible to beat a Gothic Chess engine using strategy. Ed Trice has played some outrageous "losing" moves to get an engine to bunch up all of its pieces into one corner, then outplay it. Here's one game showing him allowing his king to get checked out into the open on the 4th
 rank and he loses his rook for a knight and his chancellor for an archbishop and kingside protecting pawns and lets his queen get pinned by a rook yet he still wins.

That’s fascinating to know! Have you had try this method yet? It would be interesting to see how it works for you. Is that a bullet game? That must be incredible if it's a Blitz or Rapid one.

I'm not sure what the time controls were but it certainly does not appear to be blitz. Ed has been playing the game since the year 2000. He's played Susan Polgar, Bobby Fischer, and Larry Kaufman, all GMs, all interested in his variant. Fischer even wanted to play Karpov in this variant back in 2006. There's a YouTube documentary about the match.

Please keep cheating accusations out of the general forms. Thanks!
