Go / Weiqi Opening Lesson: B K4 Corner Pressure

Use American Go Association to check legal vocabulary and Black/White coordinate notation before reading 1. B C6 | W R14.

Compare

Compare the rule cue in a side extension, a shortage of liberties, and a cut that changes the next fight; a forcing branch, a quiet move, and a conversion test; corner approach at C6, pincer at Q10, and cut point near F3; liberty count, connection, and sente/gote order check for the opening plan with B/W coordinates, liberties, connection shape, sente/gote timing, and local fighting purpose; the article's notation sample is the first thing to keep stable.

Boundary

The rule source supports vocabulary and legality checks while this page stays a composed teaching fragment for Go / Weiqi.

Use u-go.net Game Records to compare record shape, source type, and the trained mistake: saving corner territory by giving the outside group too much thickness.

Compare

Match 1. B C6 | W R14, turn order, record length, and the position job before judging whether an outside record trains the same decision.

Boundary

Outside records are context checks; the move line here remains an original teaching example, not a named-player score.

3-4 point approach and local joseki comparison keeps a side extension, a shortage of liberties, and a cut that changes the next fight; a forcing branch, a quiet move, and a conversion test; corner approach at C6, pincer at Q10, and cut point near F3; liberty count, connection, and sente/gote order check for the opening plan connected to a stable board, route, tile, or threat shape.

Compare

Compare corner point, approach side, reply shape, local liberties, and whether the outside example is about connection, cut, or territory direction.

Boundary

The anchor is a lookup guide for study shape; it does not turn this composed fragment into a copied score.

Wikimedia Commons Goban board photo is the public visual reference for this Go / Weiqi page; Wikimedia Commons Goban board photo is the public-library context image for this Go / Weiqi lesson: it helps readers recognize a physical goban board reference for coordinate, empty-board, and shape-reading lessons; used as game-material context before the reader checks the article-specific study diagram. It is a source-traced reference image, not a substitute for the composed fragment or the page-specific cue corner approach at C6, pincer at Q10, and cut point near F3.

Compare

Use the image for board, piece, route, tile, or surface context, then use the article diagram and 1. B C6 | W R14 for the exact composed line.

Boundary

The public image supports context and license transparency; it is separate from the article-specific study diagram and move sequence.

The line beginning 1. B C6 | W R14; 2. B K4 | W Q10 is a composed teaching fragment for Go / Weiqi opening plan, built to slow down a dense branch. It is not a tournament score; the page uses it as an advanced study-note example for rule and notation practice. The page-specific mistake check is saving corner territory by giving the outside group too much thickness.

Compare

Use outside material to check B/W coordinates, liberties, connection shape, sente/gote timing, and local fighting purpose, source type, and position similarity before returning to the article line.

Boundary

Use SGF move trees, player metadata, commentary, or whole game files only as context checks; this advanced lesson stays an original teaching example, separate from outside scores, player metadata, and source commentary.
