I’d like to start a discussion of Tesuji by James Davies.
This is an experiment. Can we have a book club discussion in the forum that doesn’t give away too much of the content of the book? In that vein, I request that if you participate, please really get legal access to the book and read it. Let’s post in the spirit of fair use. That said, some diagrams will be necessary to facilitate the discussion.
My notes follow.
Chapter 1. Reading
This chapter shows an exhaustive reading example that involves reading up and down a possible move tree. That looks well beyond my abilities, and I guess the point is that knowing tesuji can help us when the reading is too hard.
I don’t follow the two moves in a row comment in the following quote. He’s not talking about ko, so how does one effectively get two moves in a row somewhere?
“you lose much more by having a lot of stones captured in a sequence that fails than by letting your opponent defend where you could have destroyed him. In the latter case, while your opponent is defending you get two moves in a row elsewhere on the board”
Can someone show an example?
Chapter 2. Capture the Cutting Stones
I’ve encountered many of these ideas before in working problems, but I like having them put together by theme. I’ll have to work through these repeatedly to really get them, I think.
The cross-cut tesuji in particular seems to be over my head. I don’t know how to think about it. I realize that somehow the initial move threatens both the diagonal connection and the 2 point jump on the third line. I see lots of stones with just two liberties in the diagrams. I see a sacrifice stone. I see a double atari. I think that grasping this will definitely improve my game.
I lost track of how many of the final ten problems I got right. It wasn’t an impressive percentage, however.
