This is a Go puzzle. The sequences of moves are from Shusaku's castle
games (famous because he went 19-0).

Note the overuse of "go", and the reference to Othello, the most
painful comparison a Go player can hear.
A solver would have to:
a) figure out that it's Go that's being talked about.
b) notice the title, and connect that with shusaku (easy enough,
search for "+game-of-go +invincible")
c) figure out that the games are from Shusaku's castle game record.
This should also be easy enough, since that's what Shusaku is famous
for, and the mention of "Castle" in the blurb.
d-0.5) find the main Go site. Kiran had trouble with this, thinking
that the name/password were for one of the Go servers.
d) find the records (the main Go site has them, they can take the
name/password from the blurb).
e) search the records for the matching plays. (mostly just work)
Good hint words: Honinbo, "the title is important", JanSteen, "An
The games are in algebraic notation, which skips 'I'. This isn't too
hard to figure out, if they use any of the usual Go clients to solve
the puzzle. The way game records are stored online, however, is as
letter pairs, and 'i' is used in them. This could be a source of some
confusion, but I'm not sure if it's worth worrying about.

The years are for when the games were played. I removed them just
before the hunt to make the searching through the records harder.
Unfortunately, this had the effect of making the puzzle much harder.
A) Without the years, the moves look like a long string of moves, so
people tend to get sidetracked into actually playing them. The
name/password in the blurb should have kept people from getting too
far down this path.
B) It's significantly harder to figure out who the clues are talking
about without the years.
The changes made it much harder, and only a couple teams solved the
puzzle. The take-away lesson is that I shouldn't have changed the
puzzle after test solving.
