What is this mental illness called? I lost 11 chess games in a row and started acting like this video below and got super depressed. And then right after that I won 14 chess games in a row and now I can't stop this god complex that I am instantly better, I am premoving every single move and even after losing points I'm like 100% sure that I'm about to win and then I win. Wtf is this mental illness called?
