Dieter's study of Otake game 6
The game is one between Otake Hideo, playing White, and the incomparable Takemiya Masaki. Although I've vowed to study Otake, who's one of my idols next to Kaoru Iwamoto, it is often said that Takemiya is the best pro to study, because he plays a very natural Go that is at least superficially easy to understand, even if there is a lot of depth in his moves. This game seems to confirm that, as it is a sweeping victory of influence over territory.
Takemiya of course* blocks at and makes the good haengma of a kosumi with keima. Otake dares not making more territory at the top and invades at right away. Follows the 4-4 point diagonal attachment joseki we all know, where the invasion group lacks a base and is under pressure. makes shape for that group immediately, allowing Takemiya to attack the lower left.
- Uberdude I wouldn't say "of course" block this side, indeed with Takemiya's kosumi it is common if not normal to block the other way, the idea being you ignore the 2nd line hane connect to take sente to play the point 7. That's when the white approach is move 6 straight after forming the san ren sei and 7 is thus empty. Here black already has 7 as white made a high Chinese, which I suppose is why he blocked this way as he doesn't need sente to get to 7 to form his big moyo.
It is very important to learn from Takemiya that he does not create central moyos always: if the opponent negates that construction, his moves are always aggressive enough to attack where the opponent had neglected to play. The lower left produces another well know joseki.
is an often underestimated kind of move: even if on the second line, it is very important for the thickness of either group. - induce , enhancing Black's eye space while attacking White's. Black neglects his left side group. This is probably because the upper right provides enough global influence. Otake plays a somewhat ugly peep.
This diagram is a battle for shape. White plays double hane, intending to play a hanging connection at next, but Black plays there himself, upon which destroys Black's shape by playing the vital point of the table shape. Otake obviously refuses to connect at a which would give an ugly empty triangle and strengthens his stones with instead.
But Takemiya is on a roll. His next attack comes at , splitting the left side. When White plays the somewhat vague , attacks the eye shape of the lower left and Otake grudgingly plays . Incidentally, I was surprised to see , taking even more territory, while I would think White can use some support for all that fighting.
Both players make shape in the battle zone, then Black pushes against White's corner to create another influential group.
We see in the lower left how White's eye shape is destroyed. is hence a bold move: apparently Otake feels he cannot allow even a 4th line moyo to appear, or maybe he thinks he is thick enough to play here.
With and Otake is giving Takemiya his favourite present: more influence. I must say I'm not getting it: White is not quite thick in the centre. exposes the thinness.
Up to , White creates a position at the right, apparently trying to turn the black group above it into a target. But Black has more pleasant business to address: sets up a splitting attack.
A bit of a strange interlude is provided by -. The 20-ish points at the bottom do not outweigh a central capture, so Black responds at . Even so, shows a clear intention of killing a group. is a beautiful resistance.
... as makes miai of a and b, the latter creating shortage of liberties. I find it impressive to see how Takemiya keeps things simple. He's in command and there is no need to resolve to ko. lives at the bottom and Black continues to attack the other white dragon.
is extremely thick. It seems Black has it all figured out. Indeed, with the third white group is under attack.
Black lures White into a small gap and splits it at . Next, is another surprising eye destroying move. Incidentally a does not split White, so all appears not to be lost. I cannot read this life and death problem, but I believe firmly Takemiya had it all figured out when he captured at move 141.
