Gokyo Shumyo, Section 1, Problem 71 / Solution

Main line: Hashimoto Utaro
Variations: Nando, Dieter

The 1-2 point

Main line

After Black 5, White a is answered by b. This is an example of oi-otoshi.

Variation at 2

Black 3 makes miai of a and b for life.

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

Blocking

Black 1 is a wasted move. In comparison to the main line, he falls one move short in answer to White's placement at 2.

Bending inward

Black 1 fails: White 2 leaves a and b as miai to kill.

Expanding

Black 1 expands the eyespace and again White answers at 2 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. White 6 makes miai of a straight three big eye at a and a false eye at b.
