I've never been a serious chess player, but I can imagine you can study it forever. I just read that the chess columnist for The Guardian has been doing that job for 70 years! It does not surprise me that some kids are really good. I see some doing music stuff online that is beyond me. I'll just be the old man they can beat.

I didn‘t know that about The Guardian, I will check it out. I remember that The Scotsman used to have a chess column so good I was reading it when I lived in Dallas before everything was online. Maybe we can play a game at our next meet-up!
