Has your chess piece ever moved by itself?

The game only does what you explicitly ask it to do, a network issue would stop all requests. I didn't look at the pre-move code details when I looked at the code a long while back.

Perhaps if the move is rendered client-side in your browser, but is validated over a network? Guessing there like anyone else here, but moves are explicit requests to the server and from the server.

Have you had the same issue with different keyboard and/or mouse? Perhaps there is a fault in the device(s) that sends movement signals?

Folks do tend to invent wild fantasies around stuff being hacked and they're the target of it, but the real world news is that most people are not worth the effort. A lichess site is already niche, but the skill required to hack lichess effectively is a bar very high that low-level account takeover is not only a waste of time but serves no point.

It likely isn't anyone external messing with the accounts of this site
it likely isn't someone targeting someone
It is likely a problem local to the person having it and they haven't troubleshooted it effectively, so imagination is taking over to silliness :)

If you can replicate it, please do so and send to lichess support. It could affect all of us if it is a true bug. If it only affects you, then it is likely just you.

Yeah let’s be honest why would a hacker(who can probably do something more valuable with his time) hack someone’s account and mess with them?
Like what is even the point?

Once, during my opponent’s turn, I picked up my rook on the flank with the mouse and hovered it over a planned square to see if the move would work. When I tried to put it back, I accidentally dropped it on a different square, which caused a mistaken premove. I didn’t notice at the time, so when the piece moved automatically on the next turn, I was shocked. Later I realized it must have been my own misclick that caused it.

Look I know this sounds funny, crazy, or a conspiracy theory, but it is true. I am not saying I am important enough for someone to mess with me specifically. But in other online video games there are hacks to let's say auto-aim so someone doesn't miss, etc. The strange thing about my incidents is it only happened with 2400 & up players who were about to flag out during tournament bullet. Maybe those specific players had some type of hack mode ability to move their opponents' pieces in the last seconds so they don't lose. Heck maybe there is backdoor code that was installed in this site program when it was created? Just a theory. That is why I was asking if it happened to any other players on this site...

Yes, but my chess set was haunted.

Unfortunately, I did not write down the games where my piece moved by itself. If it happens again, hopefully not, I will make a note and report it to the website administrators.

When you're playing a chess hustler, be careful not to look away because your queen might move by itself and place itself en prise!

That is funny,.. I have played a chess hustler over the board one time & he supposedly accidentally knocked a couple of pieces off the board reaching for the clock. When he picked up the pieces he conveniently didn't replace one of my pieces. So yes my piece disappeared / moved off the board :) it wasn't a hack it was a hustle :)

I'm not saying I am important enough to be hacked or messed with, I am suggesting someone or a few players may have some type of cheat mode to move an opponent's piece when convenient for them to win... just a theory from what I experienced... & I wrote this post to see if it happened to anyone else on this site,..

When I see my pieces move by themselves, I know it's time to sleep..

& if anyone thinks my theory is far fetched...

There was an incident a while back with an online poker program; where there was a real-world scandal involving the online poker site Ultimate Bet, where a "superuser" account was created to see opponents' cards. A similar incident also occurred at Absolute Poker. The events unfolded in the mid-2000s and came to light in 2007. Programmers created a "superuser" account with the ability to see all opponents' hole cards in real-time, giving a few players a massive, unfair advantage.

Maybe a program was created to move an opponent's chess piece, to gain an unfair advantage??
