interesting  

I have to admit that I only considered hane to either side (a, b) and had thought of nice continuations for White.
The original idea was to build up strength (leaning attack in order to reduce the black right side, e.g. L4).

I did not consider at all his quiet nobi c and took much time for playing this move [ext] http://www.dragongoserver.net/game.php?g=130113&a=move&c=kp, which is in line with the original idea of reducing the right.
Many other -unplayed - variants are very interesting.

[Diagram]
boring  

I found everything else better than playing the boring W1 (We would even be detrimental for the right side). The common sequence Wa, Bb, c-g-h-i-k-l-m etc. would be globally even worse).



  • Vs. 1 kyus:

Actually a good H4-game, which I evtl. lost by 12.5 points:

my previous move was inspired by a famous Sakata's move - move 120 of this game below:
[ext] Fujisawa Shuko - Sakata Eio (w)

Afterwards there occurs some nice shinogi/sabaki in our game, with lots of sacrifices after this move: [ext] http://www.dragongoserver.net/game.php?gid=33711&move=69

moves 1-10

moves 11-20, 19 = gong yi fei  

tderz: atari B2 is simply a fundamental mistake, has to be on B4. B6 is consistent with the overal situation (tengen).

[Diagram]
variation  

tderz: "Kong Jie´s teacher" mentioned that these B8 & B10 are so much easier and much better.
The corner is worth 20 points, the whites side 30 points, but only after reinforcing.
The conversation was in Chinese, he mentioned W9 is "gong4 yi1 fei1(?)" (that´s what my western ear heard, I have to look for the characters for the "gong".

My moves seem to want to reduce White´s influence lightly with cutting-sabaki, however with the big drawback that I compromise/damage my corner. During the game, I thought slightly about this var, but did not consider it to be my style - however if have to change my style then.

He asked me whether I understood, and was really happy when I repeated "gong4 yi1 fei1(?)". He really looked (unshaved, tired looking, eye-walls, almost drunk appearance) like the character (4?) in Hikaru-no-Go in vol. no. (?) who is called-in to punish people when cheating for money, just that he was wearing underwear. He seemed to be very strong in the fundamentals, he played many moves instantly and could explain my mistakes crystal clear with many proving variations.
If he later lost a semeai, it is more likely that he played everything on routine and did not expect me to go an unconventional way. Later he compared "German playing style" with soccer and praised my "stubborneness".

[Diagram]
moves 21-30  

tderz: black+circle, B2, B4 are a sabaki-technique, but it´s still all wrong, as explained above.
B6 should be at B7 as in the proverb.
W9 looks to me like a mistake by White (we did not discuss this, however it links up.).

tderz: Black failed to foresee the effective W3 - hence there is no (good) sealing-in of White's group.
Black cannot capture, only sacrifice.

tderz: B6 is wrong and can not be justified with the wish to construct a big moyo.
"Kong Jie´s teacher" mentioned that in Chinese, W7 is worth "32 points".
I knew that the Josekis with B7 lead to black corner territory, but this difference is indeed shocking.
Again, I have to adapt my concepts.

[Diagram]
moves 58 - 67  

tderz: B3 (sweep), taking White´s base is still wrong, despite that B5 is consequent (though it could be more to the left).
Did I forget the preferred continuation instead of B3?
B3 better at e, White will establish base, but still could block the center.

tderz: W2 is the 2nd invasion.
B3 and B5 are both bad.
Both have the sense of trying to kill and are superfluous.
Better to block from above.

unbelievable - White to move  

To my own defence for this groggy position (White is everywhere in the ropes), I must say that I pointed out a crucial error to Marc , otherwise I had captured the K10-13 stones in midgame, so I let him take back a move. Objectively this should not have been possible, but in a commentary, one is always playing against oneself.

As is apparent there is indeed a weak - correct to say 'dead' - cross-marked K16 group at the top edge (circled on GD - are not all Sensei markings possible?), which occurred after White was too greedy (wH16) near the strength and did not just escape. Also, the other cross-marked group is dead.

Black played a superb honte move at G9, creating the turtle shape (xx at H8-9) instead of allowing aji by e.g. G18.

The position is quite correct, I'm at present not very sure about the K2,3 stones, but the 3rd group is also not very stable, if Black would play R, then sente S threatens, whereafter Black could make the eye Q false by black P.

Where could White play now?
