How to create custom tactics modules?

I would like to create / obtain custom tactics modules for my son (this is his account).  Two use cases so far:

1. Tactics arising out of games the correspond to his core openings as Black and as White.

2. Tactics that were present in online chess.com games that he played.

Is this do-able?

Not with the site's tactics trainer or tools.

I'm not aware of anything for 1 and I run all my games through local analysis and mark my own tactics, though the program I use, SCIDvsPC, has a method to do it (which I've tried using before, without much success).

Easy but time consuming. Have him play several games on this site. Then run the online computer analysis. It will say what his mistakes were. Screenshot the appropriate positions and write down the solutions. Fit the screenshots onto pages, print, and have him work through them daily.

Chess.com should enable this software. It would just have to loop through a database of games and look for all situations where a [ > 1 ] pawn advantage could be crystallized with proper play.  And present it a as a puzzles "pack."

That would take quite a few resources. I know they pull some of the Tactics Trainer tactics from games but from running manual evaluations and looking for tactics, it really isn't easy to pull out good ones.

Pretty sure Lucas Chess  will generate tactics quizzes based on games that you import; well first they analyze the game and then generate the quiz.  BUT this was 3 years ago and I haven't checked lately.  Seem to remember importing a block of games and then waking up to some custom tactics the next morning.  Let me run over there and see if it's still a feature...

Yep, it's still there...

thank you!

Glad to help.  Think I might put it on my "to do" list myself, so thank you for reminding me it existed.

I'm trying to do this myself. However, after I did a "mass analyze" and started doing the tactics i discovered that 1. some were too difficult for me an I wanted to remove them (I have 145) and 2. that each one wanted my to play out each variation to 10 moves, which I find to be far too long (i'd prefer 1-3 move combos). Does anyone know how to do either of these two things?

Edit: Basically, how can I curate the pool of moves that I want to train on?

Chesstempo has the ability to sort tactics by rating, opening, number of moves, number of times missed, etc. It's not the easiest site but is powerful.
