[net.games.go] 2nd try at life and death #3

lew@ihuxr.UUCP (Lew Mammel, Jr.) (02/15/84)

Here is the board again:

	   P  Q  R  S  T
	7  .  .  .  .  .
	6  .  O  .  O  .
	5  .  .  .  O  .
	4  .  O  O  @  .
	3  .  O  @  .  .
	2  .  O  @  .  .
	1  .  O  .  @  .

The problem is for black to save itself, moving first. I proposed
T3, but this doesn't work because of white-T2, which takes away the eye
at T1 . I thought black could get eyes at S3 and T2 but white prevents
this with T5. This threatens T4, but black can't play T4 because white
could then capture with S3.

Not having learned my lesson, I now believe in black-T2. This makes
an eye at T1 and defends the stone at S4 through the sequence, white S3,
bT4, wT3, bS2 (takes). This leaves eyes at T1 and (T3 or S3).

If white plays T4 black answers with S3, forming shared eyes at T1 and S2.

Good work, Lew.  I was fortunate enough to consider the one-two
point first, through no particular brilliancy of my own, but from
that work I mentioned previously: Go Proverbs Illustrated by
Kensaku Segoe.
Yes friends, it slices, it dices and it converts into a waterbed...

Anyway: "strange things happen at the one-two point".
I excerpt:


	K  L  M  N  O  P  Q  R  S  T
   10   *  .  .  .  .  .  *  .  .  .
    9   .  .  .  .  .  .  .  .  .  .
    8   .  .  .  .  .  .  .  .  .  .
    7   .  .  .  .  .  .  .  .  .  .
    6   .  .  .  .  .  .  .  .  .  .
    5   .  .  .  .  .  .  .  @  @  .
    4   *  .  .  .  @  @  @  O  .  .
    3   .  .  .  .  @  O  O  O  .  .
    2   .  .  .  .  @  .  @  O  .  .
    1   .  .  .  .  .  .  .  .  .  .

--------------------------------------

    Black = @    White = O

This example really shows to good things to remember.  First, White to
play and live.  Where does White move?  Secondly, if White is *silly*
enough to play P2, where should Black respond?  The interesting answer
to that comes from another proverb: "The enemy's key play is my own
key play".
