I left chess in 2012.
I did not touch it for several years.
Then I decided to test my strength in Internet blitz.
I started from scratch.
The board floated before my eyes, and my knee twitched.
Less than two months later, I crossed the grandmaster rating mark.
My opponents, among them lots of players with a big name, played chess better than me.
Surprisingly though, I knew more.
On a small island of chess theory, onto which I lured them, I was better oriented.
Much better About 30% of the game.
