Also, I once played with a Korean exchange student in college, and quickly learned that the Koreans have a few subtle but significant differences in how they play. Some of the starting positions of the pieces were different, for instance, and the differences radically changed the strategy.
It might be worth mentioning that the pieces are typically round disks with chinese characters written on them to denote what piece it is; more valuable pieces are on larger disks. In the sets I've seen, the opposing sides were red and green, rather than black and white.
