The Open Singles Championship Draw

[<<] [>>] by David Maugham at Cheltenham
29th June 2014 (AC - Championships)

The basic format of the qualification is a Burridge Swiss, in that once a player has got a set number of wins or losses (half the number of games to be played) they either qualify or can no longer qualify and therefore do not take part in the Swiss any more. Due to the way a pure Swiss works, it has been seen as being unfair that the people who win continually get stronger opponents, and also that a player getting an early loss in will generally play weaker opponents. As a consequence, last year we introduced the idea of pre-drawing the first six rounds, and doing so in a such a way that all the players got a mix of opponents whose grades averaged out to that of the average of the whole tournament.

The table below is the result of this pre-draw, with the first column being an alphabetical list of players, and the 6 subsequent columns being the people they will play in the first 6 rounds. Once these six round are over, the system will revert to a pure Swiss (i.e. people on the same number of wins will play one another), although there will be some attempt to maintain the Average Opponent Grade by pairing people to minimise the outliers.

The plan is to play 11 rounds, with 6 wins qualifying (and 6 losses going out), but there is always the possibility that circumstances (weather most likely) will conspire to reduce this.

Also, I should point out that the entire main event, including the Swiss, is mandatory Super-Advanced throughout (this is a change from the printed fixtures book, which was amended on the CA website in May). SA is optional if both sides agree in all the other events (doubles included), and I will almost certainly impose it in the semi-finals & final of all the events.

There are an odd number of players, hence there are some cross-round games, which will look like some people having two games in the same round.

Some technical details about the pre-drawn Swiss:

The average grade was 2197 based on the grades as at 20th June

The total range of variances of AOG from the AG was between -9.49 and 10.34

The standard deviation of the AOGs was 4.9
