In the 16th century, it was common in Korea to play Sunjang Baduk.
From the early nineties on, through the efforts of the older master Cho Hun-hyeon and his disciple Yi Ch'ang-Ho, who by then overtook the professional Go scene, Korean Go or baduk has revolutionized the entire Go world, as well on the level of tournament results, as on the level of knowledge (opening theory, shape, style). The following pages describe different aspects of baduk.

 Source: 바둑 in English Wiktionary. For sound samples of the pronunciation of the symbols, see the IPA page in Korean Wiktionary – there /p/ sounds more explosive than /b/, /a/ is long and /u/ is a deep sound roughly as in English who. For a sound sample of the word, listen to 바둑 and baduk at forvo.com with headphones or good loudspeakers.

When encountering Korean tourists, I have mentioned Baduk, and they generally didn't get what I was talking about until one finally said: "Oh, paduk!" Today, I tried: "I play paduk in Korea using Internet" and all three immediately understood me. Moreover, one girl said: "yes, paduk is very hard" which convinced me that Koreans understand the game very well, even if they don't play it. ilan
madphage?: In my experience 'bah-dook' doesn't seem to be recognized by the Koreans I've met, whereas saying something like 'pah-doo' is recognizable.
iopq: It used to be romanized as "paduk." Does anyone know if the first sound is aspirated or voiced?
Sandra: Long story short: it is aspirated but there is one other letter that is even more aspirated (and an even bigger candidate for being romanized as 'p') and one that is less. So yeah, it sounds more like 'p' than any other western letter but there’s an even more 'p'-sounding Korean letter.
I've never heard of that. The standard description is that ㅂ (used in Baduk/바둑) is unaspirated; ㅍ is aspirated; and ㅃ is tensed and unaspirated. At the start of a word, all three are unvoiced.
Best pronounced word on baduk should be spelled bah-dewk. Never pronunciate it as bad duck. Koreans won't understand it.
PJTraill: I have added the IPA transcription from English Wiktionary (same as in Korean) and a link to their sound samples for their usage of IPA; /p/ and /b/ do indeed sound very similar to Western ears; unfortunately I could not find a Wiktionary article with a sound sample, but Forvo has it.
