I’ve been using chat gpt to study chess recently and have found it quite helpful. what I did is I asked chat gpt to give me all the most common lines of the ruy Lopez and then made it go into great detail on every line, sub line and variations. I played all the variations on an actual chess board and have learned a lot on it. I know that a lot of people find chat gpt very unhelpful when it comes to chess and I have found some mistakes in the lines like trying to move a pinned knight and so on but these only come in sub variations. but over all it has been very helpful and I even checked some of the lines that chat got gave me love by move with other chess websites and found the same main lines. I’ve found that I get basically a free course when normally they would cost a lot.I just wanted your guys opinion and thought on this matter.
