How to delete account completely?

@SailingLutra I have been playing chess off and of for a long time and I've hit that point where I was so frustrated that I needed to walk away. I burned a couple good account names here at Lichess doing that. It was tough dropping, or in my case blundering, a bunch of games, and I can completely empathize with how you feel.

Eventually I realized I was more than my rating. Tying my identity to my Lichess rating was counterproductive, and prevented me from enjoying chess. When I returned to Lichess with this account I decided I needed to just enjoy the sport. No goals, no study plans, no hours of practice, only fun. I'm terrible playing 10+0 games, but for whatever reason I like it. I accept the fact I'll win a few games and probably lose 2-3x more. When I stopped caring about the outcome, everything got to be a lot more interesting and more importantly the games are much more fun.

Why playing if winning is not a goal? Chess is not for fun, it's a cruel game.

@Komokid Kind of off-topic, but there was a guy I knew in high school who beat me 49 straight games. I was never brave enough to play game #50 even though I came close to beating him a few times. I could get a winning position but then I would throw it away in the end game. He knew I was bad at the end game and that if he could last long enough he would catch a critical mistake and eke out a win.

@SailingLutra Why playing if winning is not a goal? I don't like to answer a question with a question, but why is "winning" the only goal? Isn't the experience valuable? We lose something in online chess when we're not face to face. I always loved playing in a casual setting, chatting with my opponent (probably another reason I like correspondence games). When I was facing a regular opponent we would joke around, try ridiculous moves, see if we could psych each other out. That interaction was more valuable to me than winning -- but winning was still very welcome. Chess is a game, the rules allow for winners and losers, but any one game you're playing can be more than that if you want it to be. You can explore a new opening, try a crazy combination, maybe chat with your opponent (not everyone is chatty like me). Don't let the game be only about winning.

Whatever you choose to do, whether that is sticking with chess or leaving the sport, good luck and safe travels.

Read the rules and do everything against them.
