- Comment[The comments were made by I-Chen Wu. Jiang Zhujiu's comments
- \(marked "Jiang Zhujiu said"\) are also added. I still keep my comments
- which conflict with his. The purpose is that you can
- find strength difference between pro and amateur's comments. And I would
- like to thank MGT for a lot of help for making the comments.]

- Comment[S4 could be more
- interesting. It can get corner
- and intrude the white group later.
- Q9 could be another choice.]

- Comment[Good move.]
- ;W[pq]
- Comment[White can not help but
- take it. Otherwise, Black at
- R2 will give white a hard
- times.]
- ;B[oq]
- Comment[R2 could be a little
- better. Black can sacrifice
- the two pieces to get a little
- bit better thickness.]
- ;W[qr]
- ;B[qg]
- Comment[Good move again. Get
- territory and attack white at
- the same time. From this move,
- it is very tough for white to
- play.]

- Comment[A very flexible move.
-
- Jiang Zhujiu said he played here was because most Dan level players know this
- Joseki, and so he played this move to make it more interesting for black.
- chuckle :-\)]
- ;B[gq]
- Comment[I prefer J3 because it
- can get territory right away.
- Later, if white enters 3-3,
- black can play at C4. If white
- plays E4, black can play at D3
- to get corner. If white plays
- at D3, Black C3 should be good
- enough. Anyway, black will
- become more flexible around the
- corner.]
- ;W[hq]
- ;B[fr]
- Comment[F2 will give white a lot of
- ways to play. Maybe, E3 is
- better.]

- Comment[Black should play at O6
- to protect his group now. I
- guess black wants to get a
- thickness for the upper side.]

- Comment[It is better if black
- connect at Q15 \(move 105\). Then white's group dies, because black has one
- more liberty.
-
- Jiang Zhujiu said the same thing.]
- ;W[nj]
- ;B[hf]
- ;W[ln]
- Comment[White made a severe
- mistake for this. White should
- play at L6 or around K13. The
- three pieces are not big at
- all. After black discards the
- three pieces, white has a real
- hard time. You will see why
- white plays very strongely
- later.
-
- Jiang Zhujiu disagrees. He played here because a black move at N2 would
- reduce white's territory too much.]

- Comment[Good move. Otherwise,

- for going home. Also, after
- this move, black can get one
- more liberty by taking J10.

- Jiang Zhujiu said black should play at L2 instead.]

- Comment[Black should play at
- E17 instead. Then white has no
- chance to win the game. The
- following sequence is: W:C16,
- B:D17, W:C17, B:C18, W:B18,
- B:D18, and W:C16\(or B13\). If
- the last move C16 is omitted,
- Black C16 will be a terrible
- attack.]

- Comment[C12 could be able to
- kill the upper white group, but
- it is too complicated to be
- 100 per cent sure. One sequence is:
- B:C12, C11, D12, C11, E11, D13,
- B12, B11, B13. If someone
- finds this not working, please
- let me know. Thanks.]
