The game is very exciting but rather difficult to understand. I'll see if I can create a few diagrams to explain a bit later.

I compiled the following diagrams from several Chinese sources offering commentary of this game.

The most interesting part of the first finale game in my opinion is the following:

starts a ko fight, ignoring ko threat :w3:

,

makes the ko much larger, and white decided to ignore the ko threat :b6:

to capture everything to the left side. Now the situation becomes a large scale life & death problem.

That's why black had to play :b4:

first in the real game. Then :w5:

saved a small tail first, before killing the corner at :w7:

as a compensation of losing the group. The game was still quite close after this exchange.

Tuo Jiaxi 3p will be promoted to 9p. He has been 3p quite a while even though he is among top ranker in China.

I believe Tuo was the top player overall in the Chinese weiqi league A division in 2013, so he's certainly among the first class of players in China.
