    [Invitation letter to Yunguseng Dojang]

    Hi all, It's In-seong Hwang 7 dan Go player in Europe.

    Please allow me to write some words to tell my emotion of announcing the 10th(double digit!) season.

    It's the 10th(!) season
    As the 1st season started in May 2011, it's been more than 3 years.
    It started with 17 members. And now, including the American version, we have more than 100 members every season.

    In the meantime, our Dojang has been developed a lot. We made the Yunguseng rating system, start managing matches, add the lesson video called 'This week's highlight' and providing the 'Personal Go report' from the last season. Ah right, one of our members, kindly made a program for practicing YD lessons! http://www.gopractice.fr/ Here you can join and practice problems that studied in YD lessons.

    This is not over I'll maintain developing YD program to help you improve and enjoy Go even more!

    You probably won't believe this, but I'm planning to run Yunguseng Dojang over 100 seasons!
    Well, it's just a beginning. If we apply this step to the game of Go, it just passed one joseki in a corner.
    So please keep our Dojang in your 'Go mind', and visit us when you have more time to enjoy and desire to improve the game of Go!

    About 75% of members renew their membership. Please check their comments on this program and teacher : http://ayd.yunguseng.com/teacher.html#comments

    hello
    I'm not a member of your school, but I greatly envoyed your free lessons, very clear and informative.

    I just watched the last one and some tsumego attracted my eye:
    it's in "Tips for solving Tsumego in real games" (http://eyd.yunguseng.com/lectures.html) at time = 52'

    In this problem you say that the general principle applies (minimize first), but I had some doubts and found that it works only because of white's shortage of liberties (which, of course can be the case in any go problem).

    However, I found this position interesting and duplicated it here (but without the shortage of libs):
    (EDIT: the new lib is at Q4. right-click + click "show variations" to see available variations)



    tips-for-solving.sgf

    It seems that in this case, black must not minimize first, but rather play the vital point first.
    Am I correct?

    Hi,

    Thanks for your post!

    You are right. After I saw your post, I checked the problem again and found a mistake.

    It's true that there's no way to kill the group with B the minimize way first. And It's not depends on the liberty A because White can live anyway(White can play R2 instead of R1 in the first variation).

    But here's the interesting stuff. Even C doesn't work too :p
    If Black plays C, White will answer T2 and save the group with two eyes. So it means it's already an wrong problem that there's no way to kill.

    First of all, I'm sorry for this wrong problem. I remember that I brought this problem from Xuanxuan Qijing or Gokyo Shumyo, the old and famous Tsumego book. So I didn't doubt that it's an wrong problem.

    Thnaks again for your post!

    Kindly,
    In-seong
