364463 enclosure
  Difficulty: Dan level   Keywords: Opening, Life & Death

Diag.: 364463 enclosure

This enclosure is often deprecated: the 3-3 invasion in it is in theory something Black can kill. But it is difficult, and in practice Black cannot rely on it.

Diag.: Yamashita-O

An example has just occurred in game 4 of the 2003 Kisei match Yamashita Keigo-O Rissei (colours reversed). After the 3-3 invasion Black 2 here was played, which is a textbook attempt to kill.

Diag.: Yamashita-O (continued)

Yamashita, however, challenged his opponent to kill him, playing 3, 5, and 7. O Rissei then resigned, leaving us with a reading problem, given the exact placing of nearby stones.
