as 棋手, we can talk a lot on the systems ..... the rules are there for 2010 Singapore Open, no one is forced to join, as 棋手, we should just hope that the systems are better and better over the years. It is very unfair to 赛务 if any 棋手 plans to force a change in rules at this eleventh hour. The main duties of 棋手 is just to concentrate on the games now and let 赛务 to worry about the systems.
as 赛务, they have to tackle the issues ....... for those problems appear in 2010 Singapore Open if any, they have to review them and plan to have better systems in future.
The recent concluded Vietnam event with 9 + 2 and 9 + 1 systems for the Top 4 and next 4, I believe they have their reasons for using the systems too.
x + 1 systems are used in China too.
The generation of such discussions just one day before the competition is very very unfair to the organisers especially when the rules are released for many many days by now.
