Gokyo Shumyo, Section 1, Problem 38 / Solution

Variation 1: an eye in the corner  

If Black answers at , White has to make miai of a and b for life.

Variation 1a (continuation)  

Demonstration of giving two eyes.

Slightly worse  

White can also live by playing at . Black removes the aji with and gets two points more compared to variation 1a.

Slightly worse, variation  

This looks frightening, but white can capture some stones. (Either a or ''b' next will win the capturing race.)

Slightly worse 2  

If White starts here, then a sequence similar to Variation 1a makes Black one point better off. Looking back at 1a, it would be as if White afterwards exchanged for , which effectively gives away 1 point.

Wrong  

White must be very careful not to play in reply to , because kills her.

Variation 2  

What about Black playing the monkey jump right away?

Variation 2 (continuation)  

White cuts at and after , Black can't play at a because of shortage of liberties. By the way, at would be a mistake.
