Is there any chess site that allows you to train tactics by repeating some number of problems over and over again?
I think Chessable is pretty close to what you want. There are courses made usually by masters, some are free, some with a price. But you can create your own course and study it too. After you study something, you need to repeat the same problem after some time.
The repetition type has 3 choices:
- Chessable Spaced Repetition: It is a special repetition type where the time between repeats are getting longer and longer (like 1 day - 3 days - 1 week ...).
- Cyclical: Repeat times are constant (like 1 day - 1 day - 1 day ...).
- Custom: This needs Pro Chessable account, you can set the times whichever you like.
For cyclical, there is a note like this from Chessable:
If you are following the Woodpecker cycle, after you complete the first cycle and the exercises start popping up for review, you can now go and set a shorter cycle, which you can do, by changing the cycle end date again, to say, two weeks from the date at the end of your first cycle.
