Has Anyone Started Chess In Their 40s?

Hi, I’m a retired chess teacher (best ELO 2390.)

Korchnoi was still world-class at 60 and ranked in the top 100 at 70.

As peccavi said, you’re limiting yourself - there is a lot of chess knowledge in books.

Absolutely - you learn a lot from reviewing, especially with your opponent.

I’ve posted before here on improving at chess - have a look at post 6 in this thread:
