Gokyo Shumyo, Section 1, Problem 71 / Solution

Main line: Hashimoto Utaro
Variations: Nando, Dieter

[Diagram]

The 1-2 point


[Diagram]

Main line

After B5, White a is answered by b. This is an example of oi-otoshi.

[Diagram]

Variation at 2

B3 makes miai of a and b for life.

[Diagram]

Variation (ii) at 2

Giving away both 1-2 points seldom represents the main line. Black easily makes two eyes at the circled points.


Failures

[Diagram]

Blocking

B1 is a wasted move. In comparison to the main line, he falls one move short in answer to White's clamp at W2.

[Diagram]

Bending inward

B1 fails: W2 leaves a and b as miai to kill.

[Diagram]

Expanding

B1 expands the eyespace and again White answers at W2 to take away one eye. Next Black plays at what seems to be the vital point, but White has a nice answer up her sleeve. W6 makes miai of making a straight three at a and a false eye at b.
