Go/Weiqi/Baduk games for MSX
I've played myself the real game and some of the MSX incarnations, and I've to say that none of the videogame versions are really good antagonists 
. As it has already been said, computer AI for GO games is very complex, quite more than for Chess. There's actually a price of some milion yens ofered by a Japanese company to construct an AI capable of beating just an _average_ GO player. And as far as I know, it's still desert.
One of the other classic japanese board games that have MSX version is Shogi.
Cool, Skyblasc. I'm sure that an AI for go implemented in an MSX system cannot be tough, but I'd like to see it. And I think that an MSX would be perfect for studying tsumegos (life and death problems) or even for netplay using Internestor Suite. Anyone? 
I'd like to have some more info regarding these games. Anyone can provide me with more info/details/screenshots/whatever?
I'll insist: does anyone have more information regarding these games? I'd like to know more.
On the other hand, do you play go on Internet? My nickname is daedalian and you would find me both in KGS and IGS servers, although I'm pretty weak at the moment, about 17-18 kyu

Not much. Just that they tend to be veryyyyyy slow to play on, and being all of them japanese, the player interface sometimes makes it dificult to try to play even if you have GO knowledge ( some games use coordinates like chess games, other expect to point and click your movement, etc....). If you go to Generation MSX advanced search and use the GENRE drop_down menu to select Boargames you would find lots of GO/Hanafuda/Shogi/Kisei/etc....
I've played GO - real board- just a couple of times, and then expanded to other board games like Shogi ( more like chess) and even Hanafuda cards. But I'm really more into MahJJong where there are really great games in the MSX catalogue ( by Game Arts and even Konami for example)
By the way, the recent Rklok auction had ( maybe still are) some Go titles.

I tried on Linux versions of GNUgo and xshogi, but never managed to play online. I don't really feel confident enough 
As I said, I have not played GO very much, but if I try again I'll look for you in the servers

Any boardgame could be suitable for netplay, and if you rely solely in 2players game don't even need to program AI
Chess, checkers, domino, Go, Poker, whatever.... Just with a nice board picture and a little chat feature to talk to other players could be a great and simple software to do to use net possibilities of the Ethernet card
Back in the old days I heard Kuniji Ikeda talk about one or more amusement halls in Japan using Panasonic turboR computer for their Go games. Don't know if this was true though...
... another interesting sidenote, y'all know that Nintendo started off with producing handmade hanafuda cards, right? 
Well !!! Good to see that finally a good AI seems to manage the GO game. Even with the 9 stones handicap and being noted that _without_ it the pro GO player won 3 matches against the supercomputer, its a good news becouse i'm sure tha algorithm can *NOW* have a chance against average player without handicaps
