QQQ

Post by Kirby »

Redundant was kind enough to inform me that my next post would be my 3000th on L19, and that I may want to do something unique. I'm not sure if it is anything that is that significant, really. It seems pretty arbitrary, to some degree.

But in honor of his conveying this information to me, this post was made simply because it will be my 3000th.

So in honor of 3000, 3k that is, I decided to post a 3k go problem (a "3kyu" problem - "triple Q" - or "QQQ", if you will):

$$ | . X O O . O X . .
$$ | X O . . O . X . .
$$ | . O . X O X . . .

Thank you, eh-hem san-kyu, eh-hem QQQ, to Redundant for letting me know about my 3000th post.

First instinct:

Click Here To Show Diagram Code
[go]$$ Black to play
$$ | . . . . . . . . .
$$ | . . . . . . . . .
$$ | . . X . X X . . .
$$ | . . . X 2 O X . .
$$ | . X X O 1 O X . .
$$ | . X O O 4 O X . .
$$ | X O 5 . O 3 X . .
$$ | . O . X O X . . .
$$ -------------------[/go]


But no, that's wrong, due to:

[go]$$ Black to play
$$ | . . . . . . . . .
$$ | . . . . . . . . .
$$ | . . X . X X . . .
$$ | . . . X . O X . .
$$ | . X X O 1 O X . .
$$ | . X O O . O X . .
$$ | X O . 2 O . X . .
$$ | . O . X O X . . .
$$ -------------------[/go]


So, presumably it's this:

[go]$$ Black to play
$$ | . . . . . . . . .
$$ | . . . . . . . . .
$$ | . . X . X X . . .
$$ | . . . X 2 O X . .
$$ | . X X O 4 O X . .
$$ | . X O O 3 O X . .
$$ | X O . 1 O 5 X . .
$$ | . O . X O X . . .
$$ -------------------[/go]


Although this is an amusing resistance too

$$ | . . . . . . . . .
$$ | . . . . . . . . .
$$ | . . X . X X . . .
$$ | . . . X 5 O X . .
$$ | . X X O 3 O X . .
$$ | . X O O . O X . .
$$ | X O . 1 O 2 X . .
$$ | . O . X O X 4 . .
$$ -------------------[/go]

Hey wait, <I'm> supposed to be 3k! Let's give it a shot!

If I'm right, it's shortage of liberties. This problem was far from obvious, but doable.

Nope! That's what I get for getting too confident in my answer! Perhaps this, then?

W can't make an eye on the right, and if W captures, black 'a' makes a shortage of liberties to deny the other eye.

@Jordus:
True, but then white still lives with some stones, even though black gets 4 stones. There is a way to kill all of white's stones. Be greedy! :twisted:
