He needs a better fan.

b143 was the losing move.

Since this is the Ing cup, they used Ing style counting. I found a picture here http://www.tygem.com/news/news/viewpage ... &findword= of the counting.



First white's 8 points of komi are represented by putting 4 white stones inside black's territory. You can see them in the upper middle of the board. Both sides have exactly 180 stones, and they fill the board with their own stones. Then you can see in the upper right white's margin of victory -- 2 empty points and 1 extra black stone = 3 points. From some other pictures it looks likely that a referee did the actual counting procedure instead of the players.

You can also see the Ing clock and one of the Ing bowls which holds exactly 180 stones to make this counting method work.

The article points out several places Tang Weixing had chances to wrap up the match. Also it calls Park Junghwan "Alpha Park".

I hope there is an English commentary on this game soon. There aren't very many opportunities to see pros turn around a losing game against top competition!

I have a lot of respect for Park Junghwan, and I think he did a great job of making the game complicated. But my feeling is that it wasn't Park who turned the game around, but Tang

When asked about the game later by some reporter, Park simply responded, "It was all losing go," and had nothing else to comment.

Yes, Tang's play was probably the dominant factor. I'm still wondering what I could learn from a professional blundering away a win. Perhaps it wouldn't be as interesting as a game in which both players created a masterpiece, but it seems there might be a few lessons there I wouldn't find elsewhere.

Game 2,
Tang Weixing defeated Park Junghwan by 2.5.
** Park Junghwan was given 4 points penalty.

Park Junghwan vs Tang Weixing 1:1

game 3-5: 10/22. 10/24 and 10/26

dunno why people keep saying 2.5, komi is a whole number, how can you have a x.5 score?

Probably because that's what wBaduk or Tygem report (incorrectly, as you note). Although komi is 8 black wins ties so it is functionally equivalent to 7.5 komi (or 7.2 or 2e + pi/2).

It shows how flexible and adaptive go players thinking is...

Tang won by 1 point + 2 points of penalty. So in the end score was W+3

Could you clarify the whole penalty thing? Never heard about point penalties in Go (but I don't follow the pro scene much - so my only comparison is Chess where you can get a straight loss as a penalty but I'm curious how Go has a more granular system in place).

It is a special feature of the Ing rules timing system. In most games pros use a main time (e.g. 2 hours) and some number of byo-yomi overtime periods (e.g. 5 times 1 minute, if you move within the minute you don't use up that byo-yomi period, if you do you lose it, use all 5 and you lose on time). In the Ing cup you have some main time (2.5 hours?) and rather than byo-yomi you can "purchase" up to 3 (?) extra time periods of something like 20 minutes at a cost of 2 points each. It is not a penalty for bad behaviour or cheating or stealing the referee's tea or anything like that.

Not that Cho got penalized for that

Go Tang Weixing! Broke the unbeatable Park's winning streak. Now we have to wait till October for the conclusion...

That statement has been false (because fractional points can occur). I don't know at what point the Ing rules were changed to abolish these fractional points.

In the lower center, you see 4 white stones surrounded by black, this is the 8 point komi. Above that in the same black area you can see 2 white stones, that is the 4 penalty points Park had to pay. And in the upper right corner you can see white's margin of victory, 2 points of territory plus 1 black stone = 3 point win. Without any penalties Park would have won by 1 point, but instead lost.

Tang had 18 seconds left on his clock before he would have to pay his own 2 point penalty.

The time controls are 3 hours main time, plus you can purchase 2 extra time periods of 20 minutes but pay 2 penalty points for each one. If you use both of those you lose on time.

That is simply not true

Alternatively, the tournament director could elect to use regular byo-yomi periods instead.

I'm sure you meant to say 4 stones

edit: re: your game one post

No, actually, without the time penalty, Park would have won by 1 point. There was a 4 point penalty, so Tang won by 3
