Paris 2005 Burzo-Motoki

  Difficulty: Intermediate   Keywords: Strategy
Motoki-Burzo 1-10  

Dieter: White is Cornel Burzo, Black is Noguchi Motoki. I know Cornel as the teacher of one of my friends. Against lower dan players, he can find the most amazing sequences. I found it very instructive how Motoki calmly dealt with his challenges. It looks very simple, almost as if I were able to play like this myself.

B7 is the 3-4 point, low approach farthest pincer. The usual pincer is at a. W8 looks very much like the 3-5 point, low approach, press variation. It is, to my eyes, a strange choice, since any wall will be neutralized by the far pincer. A two-space jump at b is more logical. I would be interested to know why Cornel chose to press. Incidentally, there are 4 pro games up to B5. White invariably plays W6 and Black pincers high (but one space more to the left, that is at a, one example being the first game of the 13th Tengen title match) in three cases.

Motoki - Burzo 11-20  

The W2-W4 combination reminds of a trick play described in Ishida's dictionary, but here the ladder doesn't work:

Motoki Burzo 21-30  

B1 calmly connects and leaves the choice to White where to suffer the damage. W6 looks like a big mistake. I think a would have been better but still advanhtageous for Black.

Tapir: White can either push at W28 (likely in sente) before drawing the attachment stone out with W20 - this seems to be a current line of play - or alternatively play W18 at a.

Motoki Burzo 31-40  

The marked Black stone makes it possible to send the ladder downstairs, instead of leaving bad potential at the upper right. (you can figure out the ladder)

Having the initiative with B3, I'm quite sure Black has the lead here. B7 painfully exposes the lack of real strength in White's position (I wouldn't have thought of it that way before seeing B7. One tends to overestimate the power of ponnuki sometimes).

The alternative  

dia. [0]: If W1 here instead of W6 two diagrams ago, there would be more aji in the ladder. Still, I guess capturing three stones is big fow Black, and his marked stone is not too affected.


(German: " ... oda jeta nich?" Just a joke for German speakers (esp. with Berlin dialect, can be erased)

The alternative-alternative (1)  

tderz: This is a geta and therewith better than a ladder..

Dieter: Yes, but I am not sure that the cut at W7 is desirable for Black.

tderz: That's why I labelled already the letters c to e. (Dieter: Yes I noticed, so we only differ in judgment) The evaluations of this white threat c to e will differ (black+circle or white+circle at circle is not yet played) from player to player.
To capture cutting stones in Geta looks attractive to me. Black has already cashed in, while White still had to come up with a plan to harras B8+black+circle in an effective way.

We could start a sub-page from here.

The alternative-alternative (2)  

tderz: If white wants to escape the geta, there waits another ladder a for her.
(A black atari at c would not be answered by d, rather by white a or b. Hence Black cannot set up the shorter & safer ladder b. (Bb-Wa-Bc-We(not Wg)-Bd-We
I do not have formed an opinion right now on which ladder would be preferable (depends on top right aji).

The alternative-alternative (3)  

tderz: White prevents the ladder ...
by directly capturing with W5,
however the connection at B8 threatens the geta B9-g again and White had to do the ugly push W9. (On the other hand, Black is divided into two groups, which might give White a chance.

The alternative-alternative (3)  

tderz: Seeing the direction of this ladder heading to the middle of the top-right black ogeima shimari, I might prefer the former editors original ladder in dia [0] above.
It will have less bad aji vs. black.
Black could still revert to the ladder of dia [0], but then B4 and B6 are aji-keshi.

The two ladders  

Dia[0]'s right edge of the ladder projects at the shimari at x, above's ladder at y.


Dieter: W5 @ black+circle. Still, there is a plain ladder, and White has sente. Better for Black, but no net. But I refer to the above diagram, where the net has the cost of the pincer stone being severely cut off.

Motoki Burzo 41-50  

W4 is an unusual but possible variation to the 3-3 point invasion. W6 looks like a mistake. Black calmly hanes at B7.

Motoki Burzo 51-55  

After establishing a safe position at the upper left, Black takes another big point at B5. One cannot help feeling that White is being pushed around.

Chin Si-Yeong (B+0.5) vs. Gu Li, Samsung Cup 2008  

Tapir: I like this line of play, because it demonstrates what is at stake with the simple push B21. Black can choose a wholly different game nothing forces Black to insist on living in the corner. In fact the corner is pretty small w/ only 16 points of territory.

Chin Si-Yeong (B+0.5) vs. Gu Li, Samsung Cup 2008 (B31 at black+circle, W32 at B27 etc.)
