I see from your recent puzzles, that you weren't kidding about liking to take your time:
Do you really spend that much time on each puzzle? Many of them show a full hour.
I opened a chess account before COVID started. Then while hibernated at home because of the world wide health issue, I wanted to learn to play chess. I spent many times on twitch and on youtube. I like to play classical chess to appreciate all the wonderful things that go on in the game of chess.
My learning procedure:
. Started to learn how to move the pieces
. Play with the computer because I don't feel the fear of screwing up (some times I play with people but I get beat up so easily. But I do play with HUMAN.
. One person on twitch has lessons on how to solve puzzles. I started to solve puzzles. He told me to do puzzle as if I am playing classical games to take my time because at my age will be difficult to try to rush things.
Is there any books you guys can recommend for me to improve based on my current rating? When I retire chess will be one of my hobby.
Thank you in advance.
