Guess Who Won (7)

Thursday, March 6th, 2008

Tang Yi (left) was paired next against Lee Hanjin from Korea in Jeongganjang Cup.

Lee vs Tang

Tang won by 7.5 points. Here is the beginning of the game:

Lee vs Tang

It’s interesting to see:

  • the variation in the lower left: White prefers to build a thick position in gote with 14 and 16 nowadays instead of taking sente with 14 to the left of 9 and leaving bad aji behind.
  • how patient Black is with 33 (in most pro games I’ve seen Black attacks at 34 instead)
  • how Black plays 43 to “threaten to build a big go threat”: it’s not in itself a ko threat since the ko on the lower side hasn’t started yet, but if White responds to 43 in the upper left corner, Black can start the ko next and then she’ll have a clear ko-threat in the upper left.

Tang Yi is playing Yashiro Kumiko of Japan next.

Lee Hajin of Korea (left photo) vs. Manami Kana of Japan (right photo) in 2008 Jeongganjang Cup.

Lee Hanjin vs. Manami Kana

Answer: Lee Hajin won by resignation. Here is the beginning of the game: after move 55 Black has more territory but has one unsettled group in the center.

Lee vs. Manami

Interestingly, the game record (from Cyberoro) shows the last move as White’s - did Manami resign on her own move?

Lee Hanjin vs. Fan Yujing

Answer: Lee Hajin won by resignation.

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.
