I would like to solve this situation: A player purchases 6 months of Brain Rook membership, starts several thousand games and after the membership expires, he doesn't renew it because he still can play already started 2500 games [for example]. It is not fair to other users.
My proposal is: After 14 days of expiration, 10% of started games (randomly chosen) over the pawn limit will be forfeited every day.
