Answer: Lee Hajin won by resignation.

Lee Hajin

There a are a lot of interesting moves even if we only look at the beginning of the game:

  • Black 15 which is a new(ish) reply to White’s invasion at 12 (well, it stopped being new several years ago, but it’s “new” with respect to the English Go books)
  • The technique of playing kosumi-tsuke with 25, then directly attacking with 27 instead of defending on the right side - which of course makes a lot of sense in this case since Black is already very strong on the right side
  • The order in which 13 and 15 are played is puzzling to me: not sure what other choice does White have for 14 (maybe playing at 20? or jumping to the left of 17?), and how would that affect Black’s choice of 15.

    Hi Sorin, what do you think it is the counterpart of playing 14 in 20 instead of the played sequence?

  2. Sorin Says:

    Hi Nacho,
    If White responded Black 13 at 20 instead, the only consequence I see is that White would have less strength in the lower right (since Black could then force to the left of 10).
    In theory there is also a different effect on the ladders that would start in the upper-left, but I don’t see anything substantial for now.
