Prologue: Pieces Gain Power from the Second Move

A single piece can move widely along a straight line, but to flank an opponent, a friendly piece on the opposite side is required. The value of a piece is not just its mobility, but also its ability to form a flanking line with another friendly piece.

Move the Relationship, Not the Piece

Moving one piece forward changes the lines of alignment with friendly pieces, the lines of exposure to the enemy, and the distance to the edge. Moving one piece alters two lines.

Essence of this section: Evaluate not only the safety of the destination, but also which pieces it can flank and which pieces it risks isolating.

Protect the Piece After Capture

If a piece successfully flanks an enemy piece and becomes isolated in the enemy’s territory, it becomes a target for a counter-flank in the next move. Compare not just the number of captures, but the connectivity of the remaining pieces after capture.

The entire formation after capture is a single move.

Essence of this section: Choose a move that keeps the captured piece active, rather than one that removes it from play.

The Opponent Sees the Same Lines

The flanking line you target may also be a rescue line or counterattack line for the opponent. Do not rely solely on your own conception; instead, consider which support points the opponent can remove in one move.

Essence of this section: Beyond a completed flanking, consider the opponent’s minimal move that could disrupt it.

First Volume: The Essence of Formation—Avoiding Isolation

Only when pieces have identical capabilities does positioning take on strategic value. Form a vanguard, a support point, reserves, and a blocking role within the formation.

Avoid Hasty Advancement Without Support

A piece advancing deep into the center expands its attack range, but if the line behind it is broken, it becomes surrounded. The vanguard must retain a retreat or reinforcement path.

Essence of this section: Focus not on the distance of advancement, but on which directions friendly pieces can join in the next move.

Distinguish Between Clustering and Rigidity

Closer pieces can defend each other, but they block each other’s straight-line movement. A good formation does not stick together; instead, it maintains the necessary gaps and space for movement.

Coordination is better than adjacency. Leave empty squares as pathways for friendly pieces.

Essence of this section: Prioritize the space between pieces over proximity, and protect the gaps where pieces can be repositioned.

Reserve Pieces Complete the Formation

Placing all pieces on the front line leaves no support when the enemy changes direction. A piece in reserve can shift to the opposite side of a flanking move, or to a rescue or blocking position.

Essence of this section: Distinguish between pieces that are idle and those that can operate in any position.

Second Volume: The Essence of Flanking—Dominating the Landing Point

A pincer capture is established when both sides of an enemy piece are occupied by friendly pieces or the edge. The landing point of the flanking move becomes the key objective.

Establish the Support Point First

Without a friendly piece on the opposite side, a flanking move is impossible. Before directly pursuing a piece, place a piece in a difficult-to-move position to open a line for the second piece. A flanking move requires two roles: a support and a mobile piece.

Essence of this section: Prioritize securing the opposite side of the target piece over chasing the piece itself.

Design the Lure to Include Escape Routes

When luring an enemy piece into a line, the enemy may escape after capture. Beyond the landing point, block the vertical and horizontal lines the piece could use next.

Traps close the exit, not just the entrance.

Essence of this section: Rather than luring the enemy in, ensure that the enemy cannot safely move after capture.

Two-Directional Captures Create Intersections

A single point where an enemy piece can be flanked in both vertical and horizontal directions is powerful. This is not a matter of chance, but of guiding enemy pieces into the same row or column and preserving the reach of the mobile piece.

Essence of this section: Do not pursue one piece at a time; instead, look for empty squares where multiple flanking lines intersect.

Third Volume: The Essence of Space—Center and Edges

The center offers multiple movement directions, while the edges act as walls and participate in captures. Neither is a simple safe zone.

The Center Holds Freedom of Transition

Pieces in the center can move in multiple directions and contribute to distant flanks. The center is more than a capture point—it is a transportation network. It is not just about occupying space, but about preserving the lines of friendly pieces.

Essence of this section: Focus not on how many pieces are in the center, but on how many directions the center can support.

The Edge is Both Shield and Blade

Under the adopted rules, the edge functions as a wall for flanking. Enemy pieces at the edge have limited escape routes and may be captured between a friendly piece and the edge. On the other hand, positioning pieces against the edge limits movement and can make defense easier.

When dealing with the edge, always consider the horizontal move first.

Essence of this section: Do not treat the edge as a safe zone; instead, evaluate who can use it first.

Empty Squares Are Part of the Formation

In straight-line movement, empty squares become part of the piece’s path. Being filled does not necessarily mean strength. By preserving one key passage, rescue and directional changes become possible.

Essence of this section: Beyond occupied squares, protect empty squares that benefit your own pieces.

Fourth Volume: The Essence of Blocking—Win Without Capturing

Under the adopted rules, victory is achieved not only by destroying all enemy pieces, but also by eliminating legal moves. Both capture and mobility reduction are considered equal victory conditions.

Reduce the Lines of Movement, Not Just the Piece Count

Instead of opening a line to capture, sometimes it is stronger to wait and close off all vertical and horizontal exits. Blocking is an invisible capture.

Essence of this section: Count not just the remaining enemy pieces, but also the number of legal lines each piece still has.

Courage to Keep a Stationary Piece Active

Pursuing a piece and removing a support piece frees the entire enemy force. A piece that does not move but traps multiple enemies is the most effective piece.

Essence of this section: Evaluate not only pieces that move and achieve results, but also pieces that remain still and restrict the enemy.

In Advantage, Do Not Increase Escape Routes

The side with more pieces should not exploit the enemy’s sacrifice to break formation. Maintain the blockade, eliminate the possibility of counter-flanking, and choose a certain reduction.

In advantage, narrow the encirclement.

Essence of this section: Choose a move that does not create new opportunities for the enemy, even if it means capturing fewer pieces.

Fifth Volume: The Essence of Victory—Deeply Engaging the Reconstructed Game

The lack of a single historical rule is not a weakness. By clearly agreeing on the adopted rules, players can deeply develop formations and victory strategies within that framework.

Begin the Game from Rule Agreement

Different board sizes, edge captures, victory conditions, and the presence or absence of a Dux all change strategy. Before the game, agree on the QuickGamesArena adopted rules.

Do not confuse reconstructed scenarios with adopted rules.

Essence of this section: Before debating ancient solutions, accurately share the conditions of this game.

In Disadvantage, Increase Connection Points

Do not rely solely on traps that return pieces to equal numbers. Create support points between distant enemy pieces, preserving multiple flanking possibilities. Do not allow the enemy a single safe reduction.

Essence of this section: When in difficulty, avoid fighting alone; instead, create problems in two directions.

Cultivate Principles from the Outcome

Because traditional patterns have not been established, observation is more important than assertion. Describe in words which formations lead to isolation and which empty squares determine a blockade.

Essence of this section: Do not treat new discoveries as ancient proverbs, but instead build upon them as modern, practical wisdom.
