I found out I had a really old account, now which one do I delete?
Here's the kicker: I made an account earlier this year which was when I really began to play chess, as previously I knew how the pieces moved but had never really played the game. I started at the trashy elo of 200 and, over these months by slowly learning openings and most importantly how to blunder less (because as it turns out, even if you "know openings" you still blunder pieces very easily, so the tip people often give that "you can totally just memorize two openings and reach 1k bro" seems to me like it's completely false unless you have the experience and developed attention/board vision to not blunder during said openings), I have reached now ~700 elo.
However, when I went to play on my phone after some time inbetween without playing (and somehow unlearning all I knew — I was like almost 600 and went back to playing like a 350) I logged onto chess on my phone by just choosing the email I usually use, thinking that was my account, but the account I previously had played on was on a different email. I just played on like normal, slowly recovering my elo which is how I got to the current almost 700.
But this means I am technically multi-account. According to the rules, I shouldn't have 2+ accounts. So I'm guessing I should delete one of them? What do I do here? Should I delete one of my accounts and stick to the other one?
