I have created this position in some of my games as well because I play the Low Chinese a lot. I never tended to play the same move that Abyssinica and Shawn did, but I did sometimes. I more recently prefer to play either the large or small knight non-enclosure of the lower right.

I was surprised by ez4u's statistics because the upper star point move is very common in my games. I have also seen it in professional games since I tend to look for Low Chinese games on Go4Go - I just love that opening. The move was just done by Gu Li in the third jubango game against Lee Sedol (Gu Li won that game - although not necessarily because of that move). The moves are also discussed in Kato Masao's books and he gives professional game examples with that as well.
