I adore chess.

Alexander Alekhine: “Chess for me is not a game, but an art. Yes, and I take upon myself all those responsibilities which an art imposes on its adherents.” – Quoted in: Daniel James Brooks (2013) Poetics. Book 1, p. 72. #Art #Chess
Me too, although I’m terrible at the game.
I did once beat a FIDE Master, but it was in a 0 1 game (10 seconds with 1 second increment) and I lagflagged him 🙂
