There are some professionals there, but no top professionals. Aditya Mehta I believe is still on the tour as is Pankaj Advani. Noppon Saengkham made his return to the tour this year. Liang Wenbo is the highest ranking professional in the draw at world number 35, along with his compatriot Lu Haotian who I believe is the youngest professional on tour at 15 years of age. Also of note Dechawat Poomjeang, who was a media darling of the world championships, is also there. Can't forget Nigel Bond either, former world runner up and defending champion here.
I was a little disappointing to see no Canadian participation. Floyd Zieglar just won his 3rd national title and it would have been nice to see him or Jason Williams (runner up) test themselves against these guys.
Though it is strange that there aren't any top professionals participating.
