Center‑First Openings
The central nine squares offer the best extension options in all four directions. Start near the center, then expand toward the side that gives the most dual‑purpose plays. Evaluate lines not only for immediate threats but also for how they compound into live‑threes and rush‑fours two moves later.
Before each move, do a four‑direction scan to forecast immediate threats for both sides. Record alternative lines and learn from post‑game analysis to improve opening consistency.
Threat Chains
A chain is a series of forcing moves designed to pace the opponent into limited replies. Pivot across flanks so your opponent can stop only one threat at a time. Structure chains to end with a decisive double‑threat rather than a single rush‑four.
Defense Priorities
Always block the square that wins on the next move for your opponent (open four, rush‑four). Only then handle potential double threats. If multiple wins exist, select the block that also disrupts secondary ladders.
Live‑Three vs Jump‑Three
Live‑three: three in a row with both ends open. Jump‑three: broken by a gap and needs a filler. Favor moves that can upgrade into two concurrent threats. Catalog examples after each game to accelerate pattern recognition.
Common Mistakes
Edge chasing and tunnel vision waste tempo. Re‑center the fight and contest critical diagonals. When behind, trade space for time and force clarifying exchanges instead of passive blocks.
Coordinates & Review
Record moves with (x,y) and mark turning points. Convert observations into checklists for future games. Use timed drills to compress analysis latency.
Ladders & Double‑Threats
Use ladders to shepherd your opponent into a path that collides with your pre‑built live‑three. When the opponent over‑defends, pivot to the opposite flank where their stones lack support.
Timing & Tempo
Sometimes a small block is worthwhile if it preserves the initiative on a more decisive line. Manage tempo by alternating probes and threats to keep the initiative.
Shape Library
Build a personal catalogue of micro‑patterns: -XXX-, XX‑X, -XXXX. Add snapshots after sessions and review weekly to internalize cues faster.
Endgame Patterns
Compress threats so the forced reply enables your next winning move. Recognize when to convert positional gains into concrete threats.
