Go / Weiqi Opening Lesson: B D4 Safe Reply

First line1. B J10 | W G17

Main mistake: cutting before counting liberties

Scan the record in three passes: first quote 1. B J10 | W G17; 2. B D4 | W Q16, then explain liberty count, connection, and sente/gote order, then use the guard checkpoint to separate the opening shape from the early habit that would overextend the position; only after that should the reader then open the closest same-game record note while the notation is still fresh.

Opening line1. B J10 | W G17

Black starts the opening plan from the lower-left corner; White takes the opposite corner instead of answering locally.

Level shapeReference note

For mixed-level readers, the record is intentionally short: it gives a reusable checkpoint around B D4 before the reader opens a level-specific lesson. Board cue: corner approach at J10, pincer at Q16, and cut point near C6. Rule check: liberty count, connection, and sente/gote order. The notation uses Go board coordinates with Black/White turns. The first two entries are 1. B J10 | W G17; 2. B D4 | W Q16, which keeps the explanation tied to first shapes, early routes, development order, and when an early threat is real.

American Go Association is the rule source to open first; use it for legal vocabulary before comparing this reference note.

Notation bridgeBlack/White coordinate notation

The B/W coordinate line is a reading aid: it anchors color, board point, and sequence. It should be read with liberties and connection before judging whether a move is a tactic or only a local shape note. In this lesson the first line is 1. B J10 | W G17.

Legal testa side extension, a shortage of liberties, and a cut that changes

A move places a stone on an empty intersection, then captures opposing chains with no liberties. Suicide, ko, and scoring details depend on the ruleset, so local lessons keep the rule claim narrow. For this page, apply it to a side extension, a shortage of liberties, and a cut that changes the next fight; one rule cue, one notation line, and one comparison.

Trap to watchcutting before counting liberties

The common trap is cutting or capturing before counting liberties. A move that looks forcing in a diagram may fail because the outside group has too few liberties or because the reply takes sente elsewhere. Here the reader's mistake check is cutting before counting liberties.

Commentary

First reading pass for Go / Weiqi Opening Shape: Safe Reply: Read the first exchange as a Go / Weiqi board-location test. The local cue is corner approach at J10, pincer at Q16, and cut point near C6, not a memorized opening name.

Main habit for Opening Shape: Safe Reply: pause before B D4, count liberty count, connection, and sente/gote order, and then test W Q16.

Mistake note for Opening Shape: Safe Reply: a forcing-looking cut can strengthen the opponent if the outside group has fewer liberties. The durable progress test is liberty count, connection, and sente/gote order.

Cross-game intuition helps only after the local rule is named. For this Go / Weiqi opening shape: safe reply page, that rule set is liberty count, connection, and sente/gote order around B D4.

The fragment has done its job when the reader can describe cutting before counting liberties in their own words and replay the first two entries.

The line beginning 1. B J10 | W G17; 2. B D4 | W Q16 is a composed teaching fragment for Go / Weiqi opening plan, built as a compact rules-and-record reference. It is not a tournament score; the page uses it as a mixed-level study-note example for rule and notation practice. The page-specific mistake check is cutting before counting liberties.

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 reference note stays an original teaching example, separate from outside scores, player metadata, and source commentary.
What to compare
  • Notation and turn order: 1. B J10 | W G17.
  • Position job and trained mistake: a side extension, a shortage of liberties, and a cut that changes the next fight; one rule cue, one notation line, and one comparison path; corner approach at J10, pincer at Q16, and cut point near C6; liberty count, connection, and sente/gote order check for the opening plan / cutting before counting liberties.
  • Image fit, source URL, license label, and whether the public image matches the same game family.
What stays outside
  • Outside scores, player metadata, event labels, table logs, SGF files, and database commentary stay outside the article body.
  • A public image is visual context, not proof that the composed move sequence happened in a real match.
  • A classic position anchor helps comparison; it is not a claim that this page reproduces that exact external record.

Classic lookup cue for Go / Weiqi

Use u-go.net Game Records as a real-record or position lookup context. This page remains a composed teaching fragment and is not a copied tournament score, named-player record, table log, or external database entry.

1Search by position type

Start with side extension shortage of liberties cut changes next fight rule. The goal is to find the same kind of board, tile, route, or threat problem before looking for an exact score.

2Compare notation shape

Use the sample 1. B J10 | W G17 to compare notation form, move length, and record density against external material.

3Check the trained mistake

Keep this mistake visible while comparing: cutting counting liberties. A useful outside record should make that decision easier to discuss.

4Keep lesson and outside record separate

Open u-go.net Game Records for real records or position context, but keep this lesson separate from copied match scores and named-player claims.

How to compare this fragment with external records

Use this as a reading route before opening external databases or classic-position references. The goal is comparison, not copying a real score into this lesson.

  1. 1
    Match the notation shape

    Start with Black/White coordinate notation and the sample 1. B J10 | W G17. Compare outside records only for notation shape before judging move quality.

  2. 2
    Anchor the same kind of position

    Use this page cue: a side extension, a shortage of liberties, and a cut that changes the next fight; one rule cue, one notation line, and one comparison path; corner approach at J10, pincer at Q16, and cut point near C6; liberty count, connection, and sente/gote order check for the opening plan Look for a similar board, tile, route, or threat problem, not an identical copied position.

  3. 3
    Read it as a reference lesson

    Compare record length, annotation density, and the trained mistake: cutting before counting liberties. That is how this page explains what a reference record is for.

  4. 4
    Keep lesson and outside record separate

    Use u-go.net Game Records for real record lookup. This page remains a composed teaching fragment and is not a copied tournament score or named-player record.
