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.
