Just stumble across an impressive ukiyo search site
http://ukiyo-e.org/

and they have some materials on go related paintings :
http://ukiyo-e.org/search?q=go+game

There even has paintings on go with associated erotica art !
This one on ukiyo-e.org
Same painting details from the british museum

The description is somewhat interesting :

Set of twelve small surimono-style erotic colour woodblock prints (and one duplicate), likening positions of love-making to strategies in the game of go; with printed wrapper showing a woman holding a tanzaku poem-card.

Thank you, those are beautiful!

Regards, Tom
