As far as I know
As far as I know, I’ve never written specifically about chess. I don’t (yet) have a post dedicated entirely to the game, why I enjoy it, or how I’m learning to play.
As far as I know, I’ve never written about backgammon either, or cards or ping-pong.
As far as I know, I’ve never written about the Korean restaurant I visited almost every Sunday in Korea, the soup I ordered, and the friends who often joined me. I’ve written about some of them, a few, but not all of them, not even close.
As far as I know, I’ve never written about the time I stood outside the pension office in Korea for 40 minutes trying to work up the nerve to go inside, figure out what I was supposed to do, and try to communicate that with the people I encountered.
As far as I know, you don’t know these things about me.
And these are just a few examples. When it comes to all these corners and crevasses, pockets of interest and insecurity I have, “as far as you know” isn’t very far, no matter how much I seem to share. And, regardless of whether you share or not, “as far as I know” about you isn’t very far either, as far as I know.
