This is definitely one of Shuei's early highlights. I think it's an excellent game for 2-3 dans to study. There's constant fighting from the get go, and you can sense each player trying to find ways to show off all the tricks in their bags. The young Sanei & Shuei refuse to budge even into the endgame -- starting two ko fights that end in some big exchanges.

The cut at :b1:

is the most common continuation for this shape, however it cannot be played when White is locally strong (see marked stones). White can trap Black inside and kill him.

And the joseki keeps continuing after this...

Many of us have heard of the arranged game outcomes by professionals -- the intentional one point win, loss or draw. Shuei was no exception to this distinguished tradition, even in his early years. Below are a series of games Shuei played with Takasaki Taisaku, 'the 1-dan who played like a 3-dan.'

In 1872, Taisaku had come to Tokyo to request games from the iemoto families in an effort to earn a rank promotion. He scored favorably in his games against the Honinbo family, so Ito Showa arranged for him to have his promotion. However, Taisaku insisted on a 5-dan rank; but since it was too great a jump he was soon rejected. This became known as "Taisaku's unreasonable claim."

The reason for his request of 5-dan was because it was the rank at which one could live comfortably as a go professional in the post Castle Games/shogunate period. After his denial, he left the go world for seven years. The rest of his life can be found on the GoGoD database.

As for these games, in that 1872 period, Shuei manages to arrange one point victories for Black in all three of their games.

This game of Takagawa's is a good example of how he could whiz & flow around the board making exchanges, and a rare demonstration of his fighting strength.

I guess that looks good, but black still has to worry about white pushing out into the middle at a. I was also worried about something like this:

I guess that looks good, but black still has to worry about white pushing out into the middle at a.

If White captures, then Black gets to enlarge territory in the corner at the expense of White. (The territory is no longer balanced here.) Blocking with :b4:

to

is a fine way to play with there is a high stone or high position on the right.

If White doesn't capture, then when she pushes out there a bad cutting point at A. Defending at B will allow Black to play C, A, E and establish a group on the left, or play the strong fighting move at F wherein Black's uncaptured stone will burden White. Defending at A directly will allow Black a powerful turn at G. White G won't do much better.

Black can break through, and gets strong on the left side. But white is out into the bottom area, which is larger than the left side. Isn't this better for white than the joseki?

When looking at efficiency only White has broken shape. When looking at settled groups, only White is under attack. After :b1:

to

, White must make a narrow jump to :w4:

, while

is well-placed to continue pressuring from a variety of directions. Black's efficiency is very high and has gained a flexible position. The territory has simply switched.

It's a good example of being flexible with your territory -- not being too stuck on whose is whose; and making advantageous exchanges through natural movement of stones.

This is certainly one of the most amazing opening fights I've seen. The shape that emerges from the bottom right is incredible. Takamiya Masaki & Cho Chikun push each others' reading to the limit in this Final of the 29th Judan title. Less than a week later it appeared in a Korean professional game, then again three days after. We can tell immediately who was studying this game and how influential it was. Things quickly go awry as Cho initiates a then considered trick play of 9 to 11. I hope you'll enjoy it as much as I did. You can find additional commentary over this game in Go World Iss. 68.
