What is the best free software to analyze my openings?
In my opinion, AiChessCoach.net is an excellent tool for players looking to improve their chess openings. It's free to use and can analyze your latest 200, 500, or even 1000 games from platforms like Lichess and Chess.com. The site provides personalized recommendations for your openings and helps identify recurring mistakes, making it easier to focus on areas that need improvement. It's worth checking out if you're interested in honing your opening repertoire based on your own game history.
The site should be just fine. It worked for me just now. Did you have a problem to access it, @dapilian?

My bad! There was another website called AiChessCoach.com which confused me.
The report is awesome. Thanks for sharing with me! I appreciate it a lot.

For general analyzing you could use wintrchess.
Its completely free. The only downside is that it works slightly different from the chess.com engine but its only like 5-10% off. Just type your username, select chess.com on the options, click search games, and then click analyze.

Hello guys. I'm not a premium member so I can't use the chess.com opening explorer to see my stats in different openings. I download my chess.com games with this python script https://www.reddit.com/r/chess/comments/9ifkaq/how_i_downloaded_all_my_chesscom_games_using/ which is incredible. It gives a pgn file for each month. I used to analyze my games with Scid which worked perfectly well. But recently I'm having a lot of trouble with it. The program randomly crashes so I'm looking for an alternative. I looked up the internet and saw some names. Scid vs PC and Arena were among them. I don't know which one to pick. My intention is not to analyze each game individually to evaluate each move, but rather I'm looking for something that I can put in some moves after I import my games and see how many games I have won/ lost in that position. If you have any experience in using these SWs please shed some light. Thanks in advance.
