Why -36 on 1/2-1/2
Почему при ничье у меня снято 36 баллов
If this is a bug, it's a useful one: we can see the engine evaluation (the engine is asked for a best move and evaluation, and "claim draw" is not a move).
Because your rating is provisional - if you play some more games, your rating becomes more stable and will change less drastically after one game.
You can't post in the forums yet. Play some games!
