Been there! Once I lost ~120 points in one sitting 🤦 I was bored and was playing without being really engaged in the game - something that used to happen frequently. I stopped that behaviour and since then been only playing only when I feel my brain is ready, rather than playing every day or week. It's been working quite well for me.

As a kid I wasn't too bad at chess but stopped playing. Recently, i.e. some decades later, I created a lichess account and due to some successful tactics and a bit of luck I won my first three games and my (provisional) rating shot up to around 1900 and I was quite surprised and happy.

Afterwards I had the expected losing streak taking me down almost 500 points in only a handful of games...

All is well though, I'm studying a bit and am steadily climbing and should reach 1600 soon.

no points, but this reminds me of being in Curacao in late 2006 at Spanish Water on a sailboat. There was a popular bar and I would take my chess set in and look for a game. This one fellow offered to play and crushed me in about ten moves. We played again - same. That weekend we played some more and he handily won every game - I said he should play in tournaments and he laughed and said he did! A Master. As long as I'd buy beers, he was pleased to sit there and beat me all day long!
