Scoring

Good day. How to understand the accumulation of points in this game ?? http://ru.lichess.org/gIVv1pf7/black

White didn't move so he lost -> a decrease of his rating.

Black won -> an increase in his rating. His rating was provisional, that's why there's a huge increase in his points.

What does provisional rating mean? Here's your answer:
