End Game Test Two Black Solution 1
  Difficulty: Advanced   Keywords: EndGame

[Diagram]
Diag.: Dia1

B1 is a nice tesuji. After W6, B7 seems to be the largest move, but...


[Diagram]
Diag.: Dia2

...after that, W1,3 are sente, after W5, W is going to win with about 1 Point.



--TuRen?

JanDeWit asks: In diagram 1, why doesn't white play her second move on black 5? The way I see it, black is going to have a hard time making life!

[Diagram]
Diag.: White 2 - Jan's suggestion

Black could just atari with 3. If white connects at 'a', black captures at 'b' (atari) or vice-versa. In any case, white's group has been 'punctured' by black 1 and white will have to pull way back to e.g. the circled point to defend. White may be better off answering black 3 with 'd' (black capture at 'a') and 'b' (black connects at 2 - he could play a ko), play 'e' in sente (black connects at 'f' and connect at the circled point in gote.

BTW - notice that if, after black 1, white plays at 'a' he is caught in damezumari by black 'b'. Black could (if I read correctly) also play 1 at 'd', but would end in gote (as opposed to the right answer).

--MortenPahle (10 kyu)

Thanks for the explanation! I'm only just beginning to get a grasp of situations like this around the edge (am I running short of liberties, who has sente/gote) and this a typical situation I'll have to learn to avoid/read correctly.

[Diagram]
Diag.: Diag A

Black 1 is good move because...


[Diagram]
Diag.: Diag B

Black can reduce White on the right in sente.


[Diagram]
Diag.: Diag C - ko

Black can then win by 1 point if he/she wins this ko. But...


[Diagram]
Diag.: Diag D

Instead, White should play like this. The result is a tie.

--Eyesore (8kyu)
