Go / Weiqi Record Comparison: Corner Pressure with B D4

Use American Go Association to check legal vocabulary and Black/White coordinate notation before reading 1. B J10 | W G17.

Compare

Compare the rule cue in a side extension, a shortage of liberties, and a cut that changes the next fight; one visible plan and one tempting mistake; corner approach at J10, pincer at Q16, and cut point near C6; liberty count, connection, and sente/gote order check for the teaching comparison 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: playing a forcing-looking peep before checking connection shape.

Compare

Match 1. B J10 | W G17, 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; one visible plan and one tempting mistake; corner approach at J10, pincer at Q16, and cut point near C6; liberty count, connection, and sente/gote order check for the teaching comparison 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 Sui Dynasty Go board is the public visual reference for this Go / Weiqi page; For open-gallery context, the page adds Wikimedia Commons Sui Dynasty Go board, which gives readers a historical Go board reference, useful when all-level notes separate long-record context from modern study diagrams; used as game-material context before the reader checks the article-specific study diagram. The fit is contextual rather than exact: readers use it to recognize the game materials, then read the actual position from the study diagram.

Compare

Use the image for board, piece, route, tile, or surface context, then use the article diagram and 1. B J10 | W G17 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 J10 | W G17; 2. B D4 | W Q16 is a composed teaching fragment for Go / Weiqi teaching comparison, built for first notation practice. It is not a tournament score; the page uses it as a beginner study-note example for rule and notation practice. The page-specific mistake check is playing a forcing-looking peep before checking connection shape.

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 beginner lesson stays an original teaching example, separate from outside scores, player metadata, and source commentary.
