Gokyo Shumyo, Section 1, Problem 35 / Solution

[Diagram]

White lives

White 1 involves some sacrifice tactics.


[Diagram]

Main line

White sacrifices a stone at 1, and then proceeds making two eyes by capturing 2 and 4, sacrificing the marked stones.


At several stages, White can make a mistake.

[Diagram]

Mistake at move 7

It's tempting to protect the marked stones, but Black 2 makes it ko. If White connects at a, Black b kills unconditionally.

[Diagram]

Mistake number 2 at move 7

This exemplifies the proverb "Get strong at Gote". White dies in gote, the worst of all events, because Black can almost fill White's eyespace with a bulky five at any time.

[Diagram]

Mistake at move 5

At move 5, White can make more or less the same mistake. Black can start a ko at a or b.

[Diagram]

Mistake at the first move

Simply connecting is not good enough. After Black 4, Black will be able to almost fill White's eyespace with a killing shape.

[Diagram]

Mistake 2 at the first move

Maybe this 1 is a candidate that comes to mind. Black grabs the vital point at 2. If W3, then B4 blocks on the outside. If White plays at a to prevent the snapback, he dies in gote.
