Six stones on the third line live
Isn't B6 better than a?
White keeps sente
White keeps sente?
Five stones on the third line : B sente
variation: 6 at 9

Try this B sente for size.
Aim at the vital point first
When Black has six stones in a row, White can not kill the stones. - fails after .
Bill: doesn't look too good to me. How about white a or white b?
SGBailey: ' at a appears to be handled by ' between a and 6. There are potential throw-ins and other complicated stuff depending what path White wriggles with.
Bill: I think White can kill, then.
SGBailey: ' at b gets ' at a.
Bill: Right. :-)
seems to be White's best play.
Robert Pauli: No, torij was right.
Kevin?: Title says 'Six Live' but these sequences only show death or seki for black. Quite confusing.
Bill: The sequence that Steve and I discussed last had no diagram. I just put it in, along with another diagram for life. Besides, seki is a form of life.
Bill: No. is the key point. captures the stones.
Robert Pauli: should connect. This results in the seki shown here, with White keeping sente, not loosing it. That's certainly worth a point less.
Bill: But if Black now plays ?
Can someone show how to live or kill with five ?
Isn't this an application of the above? With 5, whomever has sente can effectively reduce it to 4 or expand to 6. No?
Slowman: How about this? (Please check it :-))
zephi? Unfortunately, 5 on the 3rd line dies even if b has sente. After 6, b can't get 2 eyes. (note: playing b5 one space to the left doesn't work either)
nachtrabe: Sure that isn't a seki?
kevinwm: The shape shown first is a sente seki for w. Playing 6 at 7 makes it death. Stones 8 and 9 below are miai for seki.
torij?: The gote move of 4 in SGBailey's diagram seems to be the wrong approach. Aiming for the vital point before playing a hane is key. Black has a difficult time answering this because 'a' becomes a ko and anything that doesn't reduce white's liberties will allow white to play 'b'.
