Hello Go fans,

    Yes, I'm still here. It's just with the three games I have been playing
via email it's been hard to scrape together the time for problems. Anyway,
here is the answer to problem #9. As you remember white was to play and live.

	A  B  C  D  E  F  G  H  J  K
   10   *  .  .  .  .  .  *  .  .  .
    9   .  .  .  .  .  .  .  .  .  .
    8   .  .  .  .  .  .  .  .  .  .
    7   .  .  .  .  .  .  .  .  .  .
    6   .  .  .  .  .  .  .  .  .  .
    5   .  .  .  .  .  .  .  @  @  .
    4   *  .  @  @  .  @  @  O  O  Y
    3   @  .  @  O  O  @  O  @  @  2
    2   .  @  O  O  .  O  O  @  X  1
    1   .  .  .  .  .  3  @  O  O  .

White = O  Black = @  Answer moves = 1, 2, 3, ...

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

    By playing at 1 white catches black with a shortage of liberities. Black
wants to play at X and make whites eye in the corner false. But if black
plays at X white takes the 4 black stones by playing at 2. Black can only
make the a move like 2 or at Y and take the two white stones. 

    In eather case, after black 2 white can then secure his weak point by
taking the cutting stone with 3. Please note that now X & Y are miai and
if black takes one white gets the other and lives.
