Forced response

Lithel: I don't think White can win the capturing race here. Playing at B1 forces a play at W2.

[Diagram]

White's move, tied for liberties...

Lithel: After W2, black must play B3 to open up some liberties. Now the White group inside has 3 liberties left, the Black group has 3 liberties as well, and it's White's move, but Black has an additional advantage...

[Diagram]

White's move, tied for liberties...

Lithel: In this situation, playing at a now removes one of White's liberties. Approaching from the top requires the additional move at b though.

Mikesh: How about running at c?

[Diagram]

Fail from the bottom

[Diagram]

Fail from the top

Lithel: So if I'm reading this right, white is dead and black escapes. (B6 at a)

Mikesh: After W3 black may take sente and play elsewhere. White cannot play W5. She has to connect above W3 first. Otherwise B will capture there after W5 is played. So maybe W should take sente after B2 in the first place...


[Diagram]

What happens next?

LukeNine45: Good so far, but what if white extends down like Mikesh suggests?

[Diagram]

W still dies

ChrisSchack: The clamp is the best I can see, 6 at either 7 or 8 are obvious failures ... but it fails anyway on the throw-in.

LukeNine45: I moved this to the solution page.


[Diagram]

White's move, tied for liberties...

LukeNine45: In this situation, from above, what happens if white plays W1?

JoelR: Black plays B2. White cannot play at a, it's self-atari, and if White plays at b, it transposes into "Fail from the top"; Black need not play again.


[Diagram]

Black Connects

ChrisSchack: The clamp is the best I can see, 6 at either 7 or 8 are obvious failures ... but it fails anyway on the throw-in.

LukeNine45: This is what I had in mind and is quite close to what actually happened in the game.

[Diagram]

Black Connects con't

White can't connect because she would still be in atari.


[Diagram]

Getting some breath

togo: Why not doing the key play first, thereby catching two stones? White a can be answered with black b. White b would be sente, but it would be too in the first solution. Also in the first solution white can connect the two marked stones in sente after Black's first play.


[Diagram]

2nd solution?

ichundso?: what about this?

[Diagram]

follow up

ichundso?this is slightly worse because white can now capture this one stone, but it works too i think

ichundso? no, its the same since the marked stone can be captured anyways

[Diagram]

Failure

Bill: If B1, W2 is sente, threatening to move out. Then W4 saves the two White stones and captures Black's dumpling. W6 is a snapback.



[Diagram]

3rd solution?

mgelo: This could be even better for Black. After 3, both have 3 liberties, but W owes an extra approach move.

xela: This was the first thing that occurred to me when I saw this problem, but it doesn't work. See next diagram.

[Diagram]

snapback
