Lots of love here for lichess, and it's well deserved. My son got into chess over a year ago, but when lockdown came I signed him up to Chess Kids, which is pretty good for children who are learning. However, he quickly migrated to lichess, and we've not looked back. It's been an absolute lifesaver during lockdown for my 8 year old son, he learnt an incredible amount from the site. Great tutorials, great puzzles, plus he gets to see some of his chess heroes like Carlson play live. It's a fantastic community. Plus, my son was able to learn pretty much everything, including how to write his own tutorials and how to analyse games, on his own without my assistance, which just demonstrates how good and intuitive the UI is.
