Earlier quoted context omitted.
I find it odd that all my friends & coworkers in the tech industry have ended up on chess.com instead of lichess. Even beyond the fact it's totally free (and free of ads), the architecture itself is super interesting: https://lichess.org/@/thibault/blog/starting-from-scratch/NI... It must be one of the best examples of a very large scale implementation of features that are simple and easy to understand
What are the differences? I'm not familiar with lichess, but chess.com has tons of bots at various levels that you can play against, and you can have one game per day analysed by stockfish for free (more costs money). I think that's a pretty good deal.
Maia is great, probably more human than the chess.com bots.
