1) NOTES. Some problems in the http://ru.lichess.org/training have more than one solution. The system treats an alternative solution as a bug.
It would be cool to add notes to the problems. or send email to the moderator to fix the issue.
For example:
http://ru.lichess.org/training/4523
it does not matter who "eat" the white knight at the step 3, but the sytem does not accept the e8 rook for some reason.
2. HOW does the rating works?
Why I receive +18 for a 1step solution? And receive +6 for 3-4 steps solutions?
