Gomoku Opening Patterns That Win
Gomoku opening patterns that win: the reliable Hanagetsu and Umezuki openings, safe first moves for casual players, and the mistakes that lose games before they start.
Gomoku openings set the tone for the entire game. A lot of beginners think the first player wins no matter what, but the real fight is in the first few moves. This guide covers the opening patterns that actually win: from the rock-solid Hanagetsu and Umezuki to safe first moves a casual player can use, so your gomoku strategy stops being a vibe and starts being a plan.

Why the first move matters
In Gomoku the first player has a built-in edge, which is exactly why rule sets add forbidden moves (double-three, double-four) for Black. That means your opening is not just where to put a stone but how to build a shape that threatens in two directions at once.
The two most reliable openings
- Hanagetsu (花月): a diagonal build that creates an early live-three threat
- Umezuki (浦月): a vertical or horizontal build with strong central control
- Both are winning openings in standard renju theory, meaning Black can force a win with correct play
Safe first moves for casual players
- Play near the center; corners give you less room to develop
- Build connected shapes instead of isolated stones
- Keep at least two directions open so you are never a one-trick line
Common gomoku openings mistakes
- Rushing a lone stone far from your group
- Ignoring the opponent's live three while chasing your own
- Attacking before you have a second threat to back it up
Best gomoku first moves in practice
- Occupy key points early, not just any empty spot
- Maintain threats in two directions at once
- Learn to read live threes and open fours; they decide who wins

FAQ
What is the best Gomoku opening?
For Black, Hanagetsu and Umezuki are the classic winning openings; for casual play, a centered, connected start is safest.
Do I need forbidden moves as a beginner?
Only Black is restricted by forbidden moves (double-three, double-four). As a beginner, focus on building two-way threats; the rules will make sense once you have lost a few games to them.
