I 'cheated'

@Depper-Dan I can see that Lichess haven't yet banned you, but you've to be careful about having other tabs open such as Engines, Analysis Board, because it could cost you your account.The best way to avoid stuff like this happening, is to close all tabs and browsers, except the one you're playing on.

Even if you HAVE cheated, it's ok, we all make mistakes, just learn from them

@Mahith1708 its not about the points. i dont care about rating basically at the moment. But i am just concerned about my studies and all the work i put in there...
@PurePremiumPenguin Yeah that might be a good sign... yes i realized that... i will be more careful with that. But its so hard if you get stalled with 1 move to go and you look at his clock...

Guys dont be cheat because your rating is going down the cheat is bad

#9 Just because you didn't play perfectly in that game, it doesn't mean you haven't cheated. You might've used the engine for some of the moves, but to remove the suspicion of cheating, played what you're thinking of.
I'm not saying you've done this, but this is the most common way things turn out when people cheat.

@PurePremiumPenguin Totally agree with you! That is an option. But why would i then post my problem?
I now played like 600 games on lichess and about 20.000 on chess.com (same username if you want to check) and i never had a problem.
What i dont like about all your comments is that you dont get to my question...
I mean yes cheating is bad and ruins the game!! Especially online!

But is there anywhere a contact of lichess (maybe a mail) where i can showcase my problem?!

#15 Yes, you can email Lichess, their email is " contact@lichess.org "

@Depper-Dan i believe you didnt cheated, next time becareful when you open tabs

@PurePremiumPenguin perfect! Thank you! I havent found that anywhere...

You should try not to open other tabs (especially analysis board) during a game or the computer will think you are cheating. Also, I'm pretty sure you don't get banned if it says cheat detected, you just lose the game.
