Essential Basics for Beginners Struggling to Beat Shogi AI
Published
While smartphones make it simple to enjoy games anywhere, beginners who just learned how pieces move often hit a wall where they cannot beat a Shogi AI. Pushing pieces forward aimlessly often invites a calm counterattack that shatters your camp.
The foundation for winning at Shogi is keeping a balance between solid defense around your king and building an attack to breach the opponent's camp. Before rushing into an assault, let us review how to build resilient formations and opening joseki principles.
Basic Opening Piece Coordination and Castling

Gote: 9a lance, 8a knight, 7a silver, 6a gold, 5a king, 4a gold, 3a silver, 2a knight, 1a lance, 8b rook, 2b bishop, 9c pawn, 8c pawn, 7c pawn, 6c pawn, 5c pawn, 4c pawn, 2c pawn, 1c pawn, 3d pawn
Gote in hand: none
Sente: 7f pawn, 9g pawn, 8g pawn, 6g pawn, 5g pawn, 4g pawn, 3g pawn, 2g pawn, 1g pawn, 8h bishop, 2h rook, 9i lance, 8i knight, 7i silver, 6i gold, 5i king, 4i gold, 3i silver, 2i knight, 1i lance
Sente in hand: none
To move: Sente
Last move: 3c→3d
Highlighted squares: 7f 3d
SFEN: lnsgkgsnl/1r5b1/pppppp1pp/6p2/9/2P6/PP1PPPPPP/1B5R1/LNSGKGSNL b - 3
This diagram shows a standard opening where Sente pushes the pawn at 7f on move 1 to open the bishop's line of influence, and Gote answers with the pawn at 3d. Securing wide influence for major pieces like the bishop and rook is the first step of an attack. However, if you focus solely on attacking and leave your king on its starting square at 5i, a counterattack can swiftly result in checkmate.
Moving the king to safety before initiating combat is called building a castle. The center of the board is prone to fighting and dangerous, so shifting the king toward the side and rallying gold generals and silver generals around it creates a sturdy defense that withstands sudden attacks. Only once your defense is secure can you attack with peace of mind.
- Clear paths for major pieces: Push pawns to let your bishop and rook move freely.
- Settle the king in a castle: Tuck the king away from the battlefield with golds and silvers to boost durability.
- Keep defensive pieces close: Keep surrounding golds and silvers focused on defense to minimize weaknesses.
- Mind overall balance: Avoid moving only attacking pieces; develop defensive formations simultaneously.

Using and Breaking Through with the Rook, the Core Attacker

Gote: 9a lance, 8a knight, 7a silver, 6a gold, 5a king, 4a gold, 3a silver, 2a knight, 1a lance, 8b rook, 2b bishop, 9c pawn, 8c pawn, 7c pawn, 6c pawn, 5c pawn, 4c pawn, 2c pawn, 1c pawn, 3d pawn
Gote in hand: none
Sente: 7f pawn, 2f pawn, 9g pawn, 8g pawn, 6g pawn, 5g pawn, 4g pawn, 3g pawn, 1g pawn, 8h bishop, 2h rook, 9i lance, 8i knight, 7i silver, 6i gold, 5i king, 4i gold, 3i silver, 2i knight, 1i lance
Sente in hand: none
To move: Gote
Last move: 2g→2f
Highlighted squares: 2f
SFEN: lnsgkgsnl/1r5b1/pppppp1pp/6p2/9/2P4P1/PP1PPPP1P/1B5R1/LNSGKGSNL w - 4
This diagram shows Sente pushing the pawn at 2f, aiming to break through along the rook file. The rook is the most offensive piece on the board, and pushing the pawn on the 2 file to pressure the opponent is a fundamental line of attack. Bringing a silver general forward from your camp to support the rook creates an even stronger offensive front. Coordinate pawns and silvers instead of charging forward with the rook alone.
In Shogi, when a piece enters the opponent's territory within the furthest 3 ranks (ranks one to three for Black), it can flip over to promote. When a move allows promotion, choosing to promote is optional; however, promoting a rook turns it into a dragon, upgrading it into a powerful piece that moves diagonally square by square in addition to forwards, backwards, left, and right. Breaking into the promotion zone to make a dragon breaks down the opponent's defense and brings victory much closer. Dropping captured pieces in hand back onto the board to coordinate with the dragon is also an effective way to attack.
| Phase | Objective | Caution for Beginners |
|---|---|---|
| Opening | Advance pawn ahead of rook | Watch enemy pawn and piece influence carefully |
| Middlegame | Support rook with silver general | Avoid isolated rook charges that get trapped |
| Endgame | Promote inside promotion zone | Make a dragon to close in on the enemy king |
| Fouls | Avoid Two Pawns (nifu) | Verify you do not drop 2 pawns on the same file |
