Four stones on the third line die  

Black tries to expand his eyespace with B1 and B3, but White plays W2 and W4 and Black dies. B3 at a or B5 is met with W6.

Bill: This appears to be White's best play, leaving a possible seki. See [ext] Segoe's sequences.
Editor comment: Seki is a kind of unconditional life. (Six live)

Six stones on the third line another try  

Another attempt. Black is still alive. A is correct, B seems inferior. For continuations see Analysis page.


Five in row

Obviously black needs sente to save her stones. After Analysis it seems that black can unconditionaly live. Diagrams here shows one possible solution.
