Opponent copies your moves in daily chess tournament

Unless you are a professional your rating on this site shouldn't matter. Silly to play a game you're not enjoying because of a meaningless number.

Against a stronger opponent, it seems ok..

Against a weaker,..i would recommend surplace..not moving..

Is Occam's Razor anything like Gillete's?

The simplest is of the most elegant.

That also happened to me twice in my chess career

I'd suggest just report them they're just tooo annoying

It may or may not be cheating but it is unethical and extremely bad manners.

That's funny. I'm sure it's not cheating though. There's an old story where a hustler, or two of them, were trying to trick a GM like this but were out tricked by some move like en passant. I can't remember it in detail and don't feel like looking it up. There are ways around it. 

Was there ever a clear, definitive answer from a staff member/moderator to this question?

If you use conditional moves, you can get his clock running sooner in one of the games. Then use your vacation time in the other. Be creative. 

I understand how to avoid it, I just want to know if it is allowed. I am assuming it is, but I haven't seen a response from an official account.

Don't do it.

Obviously if your opponent chooses your favourite opening in one game, there's no reason you have to avoid that opening in the other game.  It will not be all that rare to play the same opening in two or more simultaneous daily games, and so the games may start with the same move.

But your moves should be your own.  You should not copy your opponent's moves in one game to play the same moves against them in another game.  You should not copy your opponent's moves from one game to play against a different opponent in another game.

This would be a form of cheating.  Additionally, you don't know where your opponent got their moves; if they were cheating and using engine analysis in their games, copying their moves could mean that you are also playing engine-derived moves in your games.

In daily chess, static resources such as books, databases, etc., are permitted.  This obviously means that you will often be copying historical games, at least in the opening - although you can only copy a historical game as long as your opponent also copies the exact same historical game.  But you have to figure out how to apply the information from those resources to the specific situation of your game and use them to come up with your own moves.  Your moves should be your own.

Chess is built upon "copying" and improving pre-existing variations.

Why would it be cheating? Up to what extent can you say it's cheating? Im sure every article, book and analysis nowadays is curated via engine checks, to prevent the embarrassment of publishing a piece with blunders and obviously to improve the quality of the article. So if anyone is using a reference for a position, chances are the lines he is reading about have already been put through Stockfish or the like. They are also "copying" them.

Do you think the variations in the most popular databases are not engine generated nowadays? Take Chessbase, for example. It's not unusual for them to advertise "thousands of analysed/commented games". When you go to the majority of those games, the only comments are just copy-pasted variations with absolutely ZERO human explanation. How do you think those variations have been generated? By hand?

You should not copy your opponent's moves from one game to play against a different opponent in another game.

That's not against the rules of the site, you are just making it up.

I'd like to see one ... It's an old menatlist/hustler trick to play copy-cat simuls, like the Derren Brown YT above.  It's pretty much guaranteed to result in improved ratings and you don't even need to know how to play chess, let alone be any good at it.

Some of you are misunderstanding my comment.

Obviously, copying historical games is legitimate.  You do this in the opening of every single game.  OTB and in live chess you can do this from memory.  In daily, you can use books and databases as a permitted resource.

But the question is whether you can copy moves from one ongoing game in another ongoing game.  If you have two games, one where you are black and the other where you are white, you can copy moves between the two games and guarantee that you score 50% even against far stronger opposition.  Effectively, you make your opponent play against himself, or you make two of your opponents play against each other.  A 600-rated player could score 50% against a GM-level opposition using this approach.  This renders the idea of competitive chess completely meaningless.

The rules say "All of your moves must be your own".  If you are copying moves from an opponent, you are not coming up with your own moves.

They also say "Do not get help from any other person, including parents, friends, coaches or another player".  Copying moves between games in the described manner is getting help from your opponent, even if you do so without their permission.

And again, if you copy your opponent's moves, you risk copying engine moves if they happen to be cheating.

I don't remember someone being banned for this specific reason.  It's probably happened, but I only see a small percentage of bans.

Yes, this is not an issue in OTB chess, as you won't be playing two games simultaneously unless you are a strong player doing a simul, in which case you are better than your opponents and have no reason to copy moves.

It's also not normally an issue in live chess for the same reason.  It's normally only an issue in a correspondence format such as chess.com's daily chess.

And you're right, a few moves won't normally get someone banned.  I've had simultaneous games that started with the same opening, simply because my opponent and I happened to want to play the same opening in both games.  The games diverged later in the opening.

this is one reason I have a "backup" opening in case my opponent decides to play my opening against me with opposite colors. helps to know more than one opening well even in blitz games so you can spice it up every now and then.

Invalid.

I can't see how this helps with someone doing the hustler copycat simul trick?  Regardless of your opening you end up playing yourself
