I think you can only blame it on the date of the tournament. Singapore Open 2006 is just right in the middle. For players who want to play as many tournaments as possible from Philippines Open to Taipei Open will choose to rest Singapore Open because of it's date of the tournament. Players cant possible attend all 5 as this will be too tiring for them. (According to Thai Team ) I agree with Khelben that countries like Korea and China are using the Singapore Open as a platform to improve the rankings of their more "junior" players. I guess different teams have different opinions regarding this matter. I also disagree that Singapore fails to attract top players. Singapore Open has been a "class" and "quality" event for many years. Those who watched it will also know. For the past few years, it has been attracting many top players all over the world to participate in it. Only for this year,some players choose to give it a miss. Not that top players pursposely choose to attend a 4 star tournament instead of a 5 star one. I think the big problem lies in the date after all. Let's see what happen next year.
