Final
Zhang vs. Guo

The final between Guo and Zhang is a rematch of the 1st Obayashi Cup final (played in 1992).

Figure 1: 1-50

The game really gets going around 19 with Guo's rather unusual early invasion (Enda sensei would continue to build with A for example but meanwhile mentions that this doesn't condemn Guo's choice).

In a sharp fight Guo goes wrong at 57 enabling Zhang to connect his stones in good shape with 58 and furthermore leaves the option to start a dangerous ko at 74. This ko gives Zhang an important advantage in this game.

Under time pressure white makes a wrong estimation of the score by playing 122. Instead of this risky move, 129 would have been enough to win with a small but secure margin. The move played enables Guo to fight back aggressively with 129 and white is in serious trouble.

(further moves omitted)

After 167 the white corner died in exchange for some black centre stones. Black yet again takes a small advantage. At this moment both players are quickly running out of time and start to play at a speed which prevents us from writing down all the moves.

Many interesting battles follow, most notably white's invasion and reduction of the upper left black territory. Finally, a severe 1/2-point ko fight follows which indicates the players' excellent feeling for the score at that moment. It indeed seems to become a 1/2-point game either way until the moment Zhang blunders and puts a chain in atari. Guo thus conquers the Obayashi Cup 1995, for the 2nd time in its existence.
