Go Commentary: Lee Changho vs Won Seongjin – 24th Fujitsu Cup

Here is a game commentary of the recent game between Lee Changho and Won Seongjin, which we reported on recently in our article Lee Changho won’t play in 24th Fujitsu Cup.

Lee Changho resigns while winning

Lee resigned this game when he was winning, but even when Lee resigned, the game was almost finished, and Won already knew he’d lose the capturing race. It’s unbelievable that Lee misread an easy move.

Lee Changho is still the most famous and favourite player to many of Go fans, and it’s such a pity we can’t watch his playing in Fujitsu Cup this year. Most of Korean Baduk fans want him to be in the international tournaments without any qualifiers, and I don’t know if Korean Baduk Association makes an exception for Lee.

A controversial ranking system

In my opinion, Lee doesn’t have to play this qualifier game for the main tournament. The current ranking system in Korea is controversial.

What do you think?

Should Lee Changho automatically qualify for international tournaments like the Fujitsu Cup? Is past performance more important than a single knockout tournament? Will you miss Lee’s games this year?

    NO WAY. Lee lost to Won and Won lost to Lee Younggu. Since the seats for Korea are not unlimited what you’re proposing is something like taking out the winner and punishing him for winning(!)and then replacing him by one of the losers only because the later has more fans and was a great player. Is this sportmanship? Why do we have contests if the number of fans or the past fame are enough?

    Let’s decide now that the winner of Fujitsu Cup (or whatever other cup you want) is Go Seigen (you can replace the name) and stop any further contest. Is that OK in your opinion? 🙂

      Adrian, thanks for your comment.

      You make some good points and I’ll let Younggil clarify exactly what he was suggesting.

      However, I don’t imagine he thinks that we should just ignore the results of the Fujitsu qualifying tournament.

      Maybe selecting players based on domestic performance over, for instance, one year, would be more rigorous than a knockout tournament? How does the busy schedule of top pros affect the quality of the game? Is an additional tournament necessary for qualification?

      I don’t know the answers to these questions, but I think it’s interesting to ponder.

        Well … David, if the selection is made based on domestic performance over one year, then maybe he has no chance! ;-)Playing in that qualifying tournament was THE chance!

        Regarding my first statement, just check it and see that he has no title right now and the perspectives are not fine either: he is out of Siptan due to … well, guesss who? Lee Younggu (shall we punish him again? LOL). He is also out of KBS Cup. What about Maxim Cup? We will see within one week …

  2. I tried a lot of variation in the last part of the game, but it seems that white wins semeai there. Black always 1-2 liberty short. I guess mr. Chnagho got the right decision when he decided to resign the game. Can somebody send me the right sequence for that semeai. Maybe i got it all wrong.

    I think mr. Changho needs to play qualifying rounds to qualify in every tournament even though he is top and famous pro. If he really are strong then he will qualify for sure.


    • Hello,

      Infact, it’s a semai between eye against no eye. Black just have to play h7, k8, k9, k10, m11 and white has to play g9 and m14 to have a chance to approach, but it isen’t enough. Since white lost his eye, black dosen’t need to play f6 to f8, but white does.

  3. Bizarre error for a pro. Though I make it that black is winning the semiai by two liberties in the variation that Younggil gives – playing the duff atari at F8 costs 2 moves – have I missed something?
