One of the greatest chess players, Lasker (ok, 27 years world chess champion) wrote a book on go. Does anyone know how good he was at go? My guess is the game was not well known in Europe at the time so he didn't have chance to shine.

Felix Dueball was the strongest player in germany at the time, and he (eventually) reached 2d.
There is a book about him (german though) by Günter Cießow: "Felix Dueball. Go-Pionier aus Berlin."
Although I read it, I can't recall reading about Laskers playing strength in it. But it might be in there, as it features quite a bit about Lasker iirc.

A game between the two:

Edward Lasker wrote a book on go and he was a strong Chess player. Emmannuel Lasker ( who may have been distantly related) was the World champion.

I assume the result, "S+1" means "Schwarz + 1", ie. Black wins by one point.

Edward Lasker was around amateur 1d in strength when he was in New York City. He and Emanuel (famous chess champion) were friends in Germany. There is a pretty good article on Wikipedia about Edward Lasker, with an extended section on go: http://en.wikipedia.org/wiki/Edward_Lasker Interestingly, Edward Lasker was one of the three founders of the American Go Association. His chess strength is often viewed disparagingly but it seems his rating, in modern terms, would be around 2500, that of a normal grandmaster.
