Yuki Satsohi (W) vs. Chen Yaoye (B)
Commentary by Ma Xiaochun.
This year's Asian TV Cup takes place in Japan. The Chinese delegation includes Gu Lingyi, Kong Jie, and Chen Yaoye. After Gu Lingyi lost in the first round [to Kang Dongyun], China's hopes rested on Chen Yaoye.
This opening is not seen very often these days. White 8 uses ladder aji, and the situation changes. 13 is a ladder breaker. Regarding the tenuki at 14, although Black gets to make a double approach lower right corner, White's shape in the upper left is also quite good, and White can be satisfied.
White 20 is a good move. Perhaps 21 should be be at 222 (low two-space pincer of 18). In response to Black's cap at 23, White 24 calmly repairs the shape. This is typical of the Japanese style. After the 25-26 exchange Black lacks a good follow-up, so we look back at 23 as the questionable move. Playing directly at 26, leaving the aji of connecting at 24, would be better.
Black's retreat at 29 should be at 36 (closer one line), because this way Black 31 should continue in the center with something like 131 (L11).
White 34, attacking Black's thinness, makes things difficult for Black. This is blitz go, so there is no time for an exact reading of the position. Even though Black 35 feels like a good move, there is no justification for letting the one stone on the outside get cut off.
Black 37 and its follow-ups show an error in judgment. Black probably has no other choice but to play 39. 46 is a great move! Perhaps Black missed this move.
If White 50 were at 129, Black would most likely stand. Of course, White already likes the prospects of fighting in this area.
Both players had considered the variations between 55 and 73. A ko takes shape, but this is a two-step ko, an extremely painful result for Black.
In response to 74, considering the all-dominating ko, Black probably must endure the connection at 76. Through 104, White consumes the corner in sente. Black will face great difficulty in turning this game around.
106 moves out, but Black has no way to use his strength. Variations where White plays 114 directly (without 112) are very complex, and White was also probably uncertain. If Black plays 117 at 118, White descends at 117, Black blocks at 121, and then White can decend below 94 as a tesuji to extend liberties and then escape. As White captures one stone with 126, victory gets closer and closer.
Black 129 is the final contest. White 136 and its follow-ups are correct, and once again a ko takes shape.
The result through 161 is a loss for Black. If Black played the hane at 139 instead of 137, White would cut at 141, and the two Black stones would be trapped.
Black 163 tries to stake the game on this fight, but these hopes are not realistic, as White is not too concerned about letting this group die.
