Death in the descent?

There may be death in the hane, but White's descent adds more than one liberty. Black cannot approach from the left.

[Diagram]

Nice try

White wins the semeai.

The kosumi offers stout resistance.

[Diagram]

Black dies

(B9 at black+circle)

B3 looks reasonable. But after W4, what can Black do? W8 is atari, leaving Black no time to make a second eye. Through B10, Black is dead.

Anonymous: But ,otoh, in this variation, black has at least 5 liberties (blocking 10 forces 12 at left of 6 to destroy the second eye) and win the semeai...

Bill: Are you talking about the previous diagram? W8 captures the Black dumpling, so that there is no semeai anymore. Black just dies.



[Diagram]

Shape, but ...

B1 makes shape, but ...

[Diagram]

White still wins

W2 is a sacrifice to prevent B9 at a.

The block perhaps offers stouter resistance.

[Diagram]

White crawls in

Black now has a few choices.

[Diagram]

Black dies again



[Diagram]

White wins again (i)

(B5 at W2)

After B1 makes an eye in the corner, W2 - B5 is a squeeze. The placement of W6 prevents ko.

[Diagram]

White wins again (ii)



Black can prevent the squeeze by connecting.

[Diagram]

Black connects, but . . .

After W7 does Black stand a chance? If B6 at W7, W7 at B6.

Can Black prevail against the descent?
