What this record looks like
This intermediate Gomoku finishing pattern uses 8 entries to compare two plans: Black J8 looks natural, but White I9 changes the timing test. Board cue: center stones around H8, open-three lane I8-J8, and defensive point I9. Rule check: open three, broken three, open four, and double-threat timing. The notation uses Gomoku grid coordinates. The first two entries are 1. Black H8 | White H9; 2. Black I8 | White G8, which keeps the explanation tied to promotion, capture timing, territory closure, final route efficiency, or safe hand completion.
Position cue
a split attack lane, a repair stone, and a defense that works only once; two candidate plans and a turning point; center stones around H8, open-three lane I8-J8, and defensive point I9; open three, broken three, open four, and double-threat timing check for the finishing pattern
Unique asset
A self-authored SVG study diagram for this Gomoku finishing pattern marks center stones around H8, open-three lane I8-J8, and defensive point I9. It is paired with Gomoku grid coordinates beginning 1. Black H8 | White H9; 2. Black I8 | White G8. The public reference image pub-gomoku-pro-board gives readers an open-gallery board or piece reference for the same game family.
Gomoku rule check
Check this before the outside record: read 1. Black H8 | White H9, name the rule source, test the position cue, and keep the mistake visible.
Open Renju International Federation / RenjuNetRenju International Federation / RenjuNet is the rule source to open first; use it for legal vocabulary before comparing this intermediate record.
Grid coordinates let the reader mark exact stones and threat lanes. The notation is only useful when read with the threat type, not as a plain list of occupied points. In this lesson the first line is 1. Black H8 | White H9.
A legal move places a stone on an empty point. Threat reading then depends on open threes, broken threes, open fours, double threats, and any rule-family restrictions in force. For this page, apply it to a split attack lane, a repair stone, and a defense that works only once; two candidate plans and a turning point; center stones around.
The common trap is blocking the visible four while missing the open three or double-threat behind it. A record example should name the hidden second threat, not only the final five. Here the reader's mistake check is blocking the visible four while ignoring the open three behind it.
How to read this lesson

Grid-coordinate threat notation
Read the sample as a threat-reading study line, not as a formal Renju tournament record or proof of a solved opening.
1. Black G8 | White J8Beginner Gomoku records identify open threes, broken threes, and the one block a reader must not miss.
Intermediate records compare the visible four with the quieter move that keeps a second threat alive.
Advanced records layer threats, forcing moves, and conversion timing so the reader checks both immediate and hidden lanes.

Common Mistake

Commentary
First reading pass for Gomoku Finish Pattern: Shape Lesson: Match move one Black H8 | White H9; move two Black I8 | White G8 to center stones around H8, open-three lane I8-J8, and defensive point I9. Then name the open three, broken three, open four, and double-threat timing check before reading any branch.
The finish pattern: shape lesson teaching point is not volume of moves. It is whether Black J8 still works after White I9 is named.
The tempting move changes the board now, but a stone can look aggressive but fail to force if it does not create an immediate open three or open four. In this fragment, that difference is visible at Black J8.
A player importing habits from another board game should slow down at center stones around H8, open-three lane I8-J8, and defensive point I9. The safe bridge is open three, broken three, open four, and double-threat timing.
Exit test: quote move one Black H8 | White H9; move two Black I8 | White G8. Then explain why blocking the visible four while ignoring the open three behind it was tempting before opening the next same-game record.

Study Questions
- Which edge detail in 1. Black H8 | White H9; 2. Black I8 | White G8 first reveals the finish pattern: shape lesson problem?
- What would change in this finish pattern: shape lesson record if the reply White I9 arrived one move earlier?
- In the finish pattern: shape lesson position, which candidate around Black J8 is tempting, and what part of open three, broken three, open four, and double-threat timing makes White I9 punish it?
- Gomoku: How would you explain the open three, broken three, open four, and double-threat timing check to someone who only knows chess or checkers notation?

Public reference: Wikimedia Commons Pro Gomoku board image is the public-library context image for this Gomoku lesson: it helps readers recognize a physical Gomoku board reference, matching pages that explain real board reading and stone placement; 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 center stones around H8, open-three lane I8-J8, and defensive point I9.
