Yamashita-O

An example occurred in game 4 of the 2003 Kisei match Yamashita Keigo-O Rissei (B) (colours reversed). After the 3-3 invasion W1, B2 here was played, which is a textbook attempt to kill.

Yamashita-O (continued)

Yamashita, however, challenged his opponent to kill him, playing W3, W5, and W7. O Rissei then resigned, leaving us with a reading problem, given the exact placing of nearby stones.

It is the positioning of the BC stone that causes some killing lines starting like White a, Black b, White c to fail. It would be nice to have some pro-level analysis of that, though.
