I was going to suggest near the start of the tournament having pool/mini-leagues for the first round, like Kirian is suggesting, but realised it would obviously be a 'next year' suggestion as it's pretty complex. So, uh... yeah. Suggestion is here now.
You could split people into leagues of, say, 8 people, with 1 month for games and the aim to play everyone four times, twice as first player and twice as second. Then have some tiebreakers in place and have the top two progress into a knockout tournament like our current one. There are a few obvious advantages and disadvantages of the system, which I'll summarise Advantages first:
- You can group players by timezone for the leagues. That way, people won't be pushed to play awkward times until 3/4s of the players have been knocked out, which makes things a little more pleasant. While it wasn't a huge concern, I wasn't exactly happy having both my rounds 1 and 2 being at -7 hours from me.
- Everyone gets to play 7 opponents, 4 times each, at minimum. That's 28 games in the tournament, no matter how well or badly you're doing.
- The results of the leagues can be a lot fairer as there are more games (and more opponents) to tier players on.
Of course, there are some disadvantages:
- You have to organise 7 different games with 7 different people. That can be a bit difficult, although having a lot more time available does mitigate it a bit
- There's potential for 'slingshotting' players through the system. By which I mean two people can conspire to get one extra wins (unlikely but possible), or once a player has guaranteed they're through, they might not worry about their other games and play suboptimally or even not turn up, knowing they can take the loss, which unfairly rewards players who play later in the sytem
Personally, I think the advantages outweigh the disadvantages but of course it's up to you guys to choose what's best.
I'd also prefer a single (main) league per year, but I'd also quite like some lower level leagues just for fun, e.g. a level <20 league.
