Chess Online: Play & Learn

Major flaw: it does not recognize en passant, in the puzzles and the Arcade games. Emails to Support bounce. ? Nice features. But forces you to start at the weakest bot. But, I worked my way up and beat it at 2750, once so far. The analysis is nicely presented, giving you the chance to find the best moves for either side. One issue: if I choose Play The Computer, I can opt for Black, White, or Random. Now, if I play the bots, I get a streak of playing only W or only B. Please make this random.

Great app that seems to evolving. I like that I can choose between Stockfish and LC0!
