@EdLee:

Your solution for #1 is correct. Looks like you're still investigating the other two, so I won't comment on those.

@Lanrose:
Your solution for problem 1 is correct.

For the second problem, continuing from your last diagram, if white captures the stone...?

For some reason I thought this would be a Ko fight but I see that white will just play and live.

While driving though i was able to come up with this sequence

[go]$$B same as before
$$ | . . . . . . . .
$$ | . X X X X . . .
$$ | . X O O O X X .
$$ | 2 O 4 6 . O X .
$$ | 8 1 3 5 O 7 . .

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


I don't know if this is the best sequence for black but it at least forces a ko fight

Anyway, the solution for this one should avoid both ko and seki, since there is a way to kill directly.

Problem 1

[go]$$B
$$ | . . . . . . . .
$$ | . X X . . . . .
$$ | . O X . . . . .
$$ | . O X , . . . .
$$ | 1 X O X . . . .
$$ | 2 O O X . X . .
$$ | . a 3 . . . . .
$$ ----------------[/go]


White can't play at a for a second eye due to a shortage of liberties

Problem 2
Click Here To Show Diagram Code
[go]$$B
$$ | . . . . . . . .
$$ | . X X X X . . .
$$ | . X O O O X X .
$$ | a O . c . O X .
$$ | . b . . O . . .
$$ ----------------[/go]


This reminds me of this problem Bill Spight posted a while back. But there's a crucial difference; if black hanes at a here and white decends at b, the resulting shape is dead instead of alive. That suggests to me that black can do better than ko in this problem and that c is a key point.

Here's my answer:
Click Here To Show Diagram Code
[go]$$B
$$ | . . . . . . . .
$$ | . X X X X . . .
$$ | . X O O O X X .
$$ | 2 O 4 1 3 O X .
$$ | . . . . O 5 . .
$$ ----------------[/go]

Another possible resistance:

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


Problem 3 (9 points)


I think this clamp works:

[go]$$B
$$ | . . . . . . . . . .
$$ | . . . X X X . . . .
$$ | . . X O O O X X . .
$$ | . . X , . . O . X ,
$$ | . . . X O 3 . O X .
$$ | . X . X O 1 . O X .
$$ | . . . . 2 a . O . .
$$ --------------------[/go]


The hane at a is answered by the same 3.

If white tries this

[go]$$B
$$ | . . . . . . . . . .
$$ | . . . X X X . . . .
$$ | . . X O O O X X . .
$$ | . . X , b . O a X ,
$$ | . . . X O 2 . O X .
$$ | . X . X O 1 4 O X .
$$ | . . . 7 3 5 6 O .
$$ --------------------[/go]

The weakness at a and the shortage of liberties at b ensure white can't get two eyes.

Looks good for problems 1 & 2.

And, indeed, that throw-in poses an issue from problem 3 :-)

@Shaddy:
Not sure I get the causal implication with the "so" in your comment.

The diagrams you provided are correct, and ko is correct for the third problem - but I didn't quite get your comment. With 5@2, where are 3 and 4?

Not sure I get the causal implication with the "so" in your comment.

The diagrams you provided are correct, and ko is correct for the third problem - but I didn't quite get your comment. With 5@2, where are 3 and 4?


Sorry, I meant 3 @ 2. Then White makes the ko-mouth and Black gives atari.

So completely forgot I never posted solutions to the last 2 problems

Both possible variations though I think the first has white defending better. Either way white dies.

And a couple variations later I came to this conclusion.

Just in time, because I'm about to post the solutions!

You're looking pretty good here, except what about this?
