I'm doing the Chess.com lessons and I think they're pretty great, but aside from that. Books?
Also, what's a reasonable lofty long-term goal? I have a ton of experience playing poker but virtually none with chess until a couple months ago. I realize no one is becoming a master learning the game at 40, but I still want to find something to shoot for.
I'm learning chess at 40 after being inspired by The Queen's Gambit. I'm curious what you guys think is the best method to study/practice and improve for someone older?
