This thread was getting hijacked by an analysis of the Chen-Iyama game, so I split that off into its own thread. For that analysis, please see viewtopic.php?f=13&t=9359&p=152688#p152688

And thanks to Trout for starting and adding to this thread.

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 , makes the ko much larger, and white decided to ignore the ko threat to capture everything to the left side. Now the situation becomes a large scale life & death problem.

That's why black had to play first in the real game. Then saved a small tail first, before killing the corner at as a compensation of losing the group. The game was still quite close after this exchange.

but they're playing inside

Thanks for the analysis, macelee. Big trades are my favorite part of looking at pro games.

2/12, 2nd game;
Zhou Ruiyang defeated Tuo Jiaxi by resign.

Zhou Ruiyang vs Tuo Jiaxi 1:1
2/13 3rd game

2/13, 3rd game;
Tuo Jiaxi defeated Zhou Ruiyang by resign.

Tuo Jiaxi is new international champion....

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.
