It’s called Igo and it was invented in Korea. It has less unique pieces than compared to chess, yet is more complex than chess by a higher order of magnitude.
I mean, if you’re going to say that the name isn’t “go” (which is certainly a common English term for the game) AND that it was invented in Korea, then surely the name should be Baduk, the Korean term for it. Igo is the Japanese name. (and for what it’s worth, weiqi is the Chinese term.) Admittedly English-speakers mostly use Japanese terms for the game, like “atari,” “joseki,” “hane,” etc., but that’s more a historical accident than anything else.
The claim that it was invented in China is actually from baseless speculation from a flawed study published back in 1993 from a Chinese university tied to a government propaganda campaign and regurgitated in an essay posted in 2004 that someone cited on Wikipedia in 2014.
You’re both wrong. Given it’s combined age and complexity, there is only one rational explanation…
Do you have a source for that? I can’t find any information on it and every Go site lists China including the British Go Association
