You may or may not know this but Go, Paduk, Qui-Chi, and Igo are all names for the same game. It doesn't matter what you call it, these names are all used in reference to the game of GO. Go is used in English, Paduk (or Baduk) is Korean, Qui-Chi is Chinese, and Igo is Japanese.
So don't be confused if you hear someone say Paduk, or maybe Igo. They all mean the same thing! GO!
