Vision and focus seem to be fading with age
Something has been growing wrong with my chess play, occurring more frequently. I've been making one-move blunders: putting pieces en prise, leaving pieces en prise, not playing mates in one. Naturally, it means I'm not seeing more two-movers, too — I've been falling to forks like a beginner. Since it's happening increasingly, I think it might be that my chess vision is deteriorating with age like my eyesight. It's scaring me.
