Of course, I'm again late
But for the future, discussions, like for 2+2 Chess Open VII:
1) Double Elimination is just not for chess. Reasons can be different, 2 games are minimum, but since it's elimination tourney, 4 would be preferable. With blitz that would be too much luck, and with slower time controls - 2 games are just too much, and if it stays 1:1, luck blitz will be needed to play. Though, this makes too much luck for chess tournament. I didn't mentioned also very important fact about the luck in pairings. Having really strong player in "Losers" bracket (let's say, he wasn't able to play Rnd 1, or received a really strong opponent in Rnd1, who is debuting in 2+2, so will have a provisional ranking) will make one player to be busted of tournament just because of pairings - not fair
Or let's say, 2 players are far ahead of rest of the field. That usually means, that 3rd place will be not the strongest guy of the rest of the field, but just one of them, who didn't met both of these for longer time than others.
Plus, draw is very important part of a chess game. Excluding it would be just unfair IMHO.
Double Elimination Works perfectly for Starcraft, or Heroes III tourneys, but not for chess
It's usually perfect format to find the best one - but not for middle strength/worse players.
2) About the time controls... For me only two things are important - the longer it is, the better I play
My favorite time control always was 120+60+30 (mins). O.K., now I don't have such a time for friendly tournament, but 30 min games are just perfect. And I just very bad about the increment thing - in my times there was no such a thing, and it's very hard to get used to it.
So, I'd prefer 30+0, 20+0, or even 15+0. But I will play in 15+2 as well
Should I send registration letter by private message, or it is enough to say it there - I'm in
