Back on topic, I’m no chess player but I had chance to teach weiqi to a few strong chess players and from their own words they like most in go was
1 The use of intuition early, avoiding the books of opening for chess
They said intuition still exists in the middle game in chess, but almost disappeared in the opening, it was mainly a library fight
2 The open minded and friendly ambiance, not to mention the free and convivial teaching in go which is strongly opposed in their chess club (already said before)
Saying that chess is less complex for human as go is still a bit stupid (like the reverse too ofc) because I can’t estimate how much the different pieces and their (different) movement make it harder for a human and this is in balance with the pure combinatoric, giving an advantage for weiqi on the other side.
