Lesson board

Star point, approach, small-knight enclosure.

Lower-left corner

Black shape

The main Black shape for this lesson. It is balanced: Black keeps the corner base while developing toward the upper side.

White base

The basic recommendation from the lesson. It is low, solid, and easy for kyu players to remember.

Sequence

setup

Black 1 star point, White 2 small-knight approach

White approaches the star point to split Black's corner influence lightly.

The Double Gun pattern starts in the lower-left corner: Black begins from the star point, White makes the small-knight approach, and Black chooses the small-knight enclosure instead of blocking White immediately.

This is a balanced beginner pattern; the important skill is knowing when the local shape is already good enough.

Future follow-up

Modern attach: stronger-player follow-up

AI-era play often becomes more active with the attach, but the follow-ups require more calculation and judgment.

Keep it as a future lesson unless the student already has enough reading strength.

Future follow-up

One-space jump enclosure: related Double Gun family

The one-space jump enclosure is a related Double Gun family, but it is not the beginner main line here.

The small-knight enclosure remains the recommended first version for this lesson.

Endgame follow-up

Boundary block and crawl: save for endgame

The corner boundary is a large later endgame area, roughly in the double-digit point range.

Do not spend opening moves there while larger whole-board plays remain.
