Originally posted by MalvinasJust an fyi, but with 20 players you only need 5 rounds to establish a winner (though this doesn't garuntee it will happen) as 2^5 = 32 > 20. Seven rounds is overkill unless you are going to have 2^7 = 128 players and even then due to draws you can probably have more than that.
I´m organizing it.
We´re 15 by the time.
I´m using Swiss Perfect to do the pairings.
