Obviously, it is fast and handy
Is chess technology resulting in better players?
I like to play bots because it's convenient and I can make moves as fast or as slow as I want. I can also experiment with different variations.
I don't like when a bot makes an obvious blunder and so it's not a substitute for playing against a human. I also find my accuracy improves when I'm playing a higher rated bot or human. But, sometimes I want to speedrun a game with a bot while I'm on the bus and only have a few minutes (but can pause at any time).
I think playing a bot will still help you practice calculating moves and reducing the number of blunders.
Now that I can halt a game and ask what the next best move is I should be in a better position to learn chess than a person from 30 years ago who relied on books. In those days I had no way to test an idea. But from what I have read, new chess stars arise from innate abilities, not learned analytical skills. Does using a Chess Bot improve skills?
