Acknowledgment: Much of what I know about Takemiya’s style is based upon
Master Play: The Style of Takemiya (2008) by Yuan Zhou, and I’ll rely heavily on this resource during this game. I highly recommend this book.
Summary of the Style: In the opening, the focus is on
quickly occupying key points and on developing a central moyo. Next, the focus shifts to
reinforcing the moyo and to repelling the inevitable invasion into the moyo. The game is often decided based on whether the invasion succeeds or fails.
Other characteristics of the style follow from the above. In order to be able to quickly occupy key points and to develop contours of a central moyo, one must
keep sente in the opening as much as possible. From this it follows that one should occupy free corners with
4-4 stones. 4-4 stones influence the center well and they are not overly threatened by approach moves (which means one can easily tenuki to take key points elsewhere on the board). The prevalent use of the
sanrensei formation in Takemiya style follows directly from this.

Furthermore, since the goal is to build a central moyo, one must obviously select josekis which result in
outside influence instead of corner or side territories. Moreover, since the moyo must be invasion-proof, one must focus on building
thick positions. This is a crucial point worth emphasizing. If the moyo lacks thickness--i.e. the walls have cutting points and other aji--the opponent will have no trouble taking advantage of these aji to destroy the moyo. Thus, one must select appropriate josekis, sacrifice stones (sometimes significant numbers of them), spend moves (later in the game) to
reinforce the moyo, and take other such measures to achieve the requisite degree of thickness.
Clarification: The central
moyo must be constructed naturally through the normal give and take of the game. It must not be forced, as this could lead to unfavorable exchanges which might be hard to compensate for. For example, playing a stone in the center of the board on move 1 is
not Takemiya style.

Considerations in Favor of the Style: Due to the properties of the edges of the board, corners and sides have many aji that one can take advantage of when invading. Thus, although the style calls for surrendering much of the corner and side territories in the opening, it might still be possible to do damage against these territories later in the game. Conversely, an
invading group cannot form a base inside a central moyo, so living inside such moyos is much harder.
Considerations in Opposition of the Style: The style calls for playing in the center, which
does not have well developed set patterns (josekis) from which to draw upon. Thus, it is often
difficult to know what moves Takemiya style requires in various positions. Moreover, although one must keep sente in the opening as much as possible, eventually one must switch focus to giving up sente so as to reinforce the moyo. Deciding
when to make a reinforcing move can be very difficult.
Furthermore, the style can be very
risky and requires strong fighting skills. Firstly, the player
must surrender a lot of solid territory to the opponent in the opening--which is an obvious risk. Secondly, the game of Go is stacked in favor of life instead of death--it takes less effort to gain liberties than to take than away (it takes 4 stones to surround 1 stone, 6 stones to surround 2 stones, etc.), so it’s
easier to live than to kill. Therefore, even though living inside central moyos might be harder than living inside moyos containing side or corner territories, obtaining
a living group inside the moyo might still be possible in many cases. Hence the risk and the requirement of being able to fight well.
