Have you done a points league? You know where, you go and play someone each week. Your score is how many points you kill. So.
1. The standings are based on how many points you score, not wins and losses.
2. Instead of having a scheduled opponent and having to find that person, you just play someone, someone you have not played yet.
3. No gambit needed,
All you need are kill points. Win loss means pretty much nothing.
4. If you miss a week. Catching up is easy just play two people that week.
5. point level, sets allowed, pieces allowed, and such can be decided when league is created.
