The Encyclopedia of Checkmates: 50+ Patterns You Must Know

You can have a winning position, but if you don't know the geometric pattern to finish it, the King might escape. Checkmates are shapes. The best players memorize these "Mating Nets" to spot them instantly.

🧩 Finish insight: You can't calculate checkmate if you don't know what it looks like. Missing a "Mate in 2" is the most painful way to draw a won game. Build your internal library of mating nets to close out games instantly.

1. Rook-Based Patterns

Pieces: Two Rooks (on 7th rank)
🧠 Hook: "Pigs on the 7th."
Two Rooks occupy the 7th rank (the "Sevenths"). One Rook checks the King, forcing it into the corner. The other Rook delivers mate. They devour pawns and the King like "blind swine."
The Kill Box 1400+
Pieces: Rook + Queen
🧠 Hook: "The 3x3 Prison."
The Rook is adjacent to the King. The Queen is one square away (diagonal). Together they form a 3x3 "box" that the King cannot escape. Usually happens when a King is trapped on the edge.
Pieces: Rook or Queen
🧠 Hook: "The Corridor."
The King is trapped behind his own wall of three pawns. A heavy piece invades the back rank.
Corner Mate 900+
Pieces: Rook + Knight (or Pawn)
🧠 Hook: "The Trapdoor."
A Rook delivers mate on the file (usually h-file) against a King trapped in the corner. The King's escape is blocked by his own piece (often a pawn on g7) and a Knight/Pawn covering the flight square.
Ladder Mate (Lawnmower) 100+
Pieces: Two Major Pieces
🧠 Hook: "Step by Step."
Two Rooks (or Queens) work together to push the King to the edge of the board, cutting off one rank at a time until mate is achieved.
Opera Mate 1100+
Pieces: Rook + Bishop
🧠 Hook: "The Masked Bishop."
Named after Paul Morphy's game. A Rook delivers mate on the back rank, protected by a Bishop on a long diagonal. The King is trapped by his own piece on the side.
Mayet's Mate 1300+
Pieces: Rook + Bishop
🧠 Hook: "The Fianchetto Killer."
Similar to the Opera Mate, but usually against a castled King. The Rook mates on h7 (or a2), supported by a Bishop behind it on the long diagonal.
Anderssen's Mate 1200+
Pieces: Rook + Pawn (or Bishop)
🧠 Hook: "The Corner Crush."
A Rook mates on the 8th rank corner, supported diagonally by a Pawn or Bishop.

2. Queen-Based Patterns

Epaulette Mate 1000+
Pieces: Queen vs. King + 2 Rooks
🧠 Hook: "Shoulder Pads."
The King is on the back rank, sandwiched between his own two Rooks (which block his escape like shoulder pads/epaulettes). The Queen checks from right in front.
Swallow's Tail (Guéridon) 1000+
Pieces: Queen vs. King + 2 Pieces
🧠 Hook: "The V-Shape."
The Queen checks the King right in his face (supported by another piece). The King cannot retreat diagonally because his own pieces block him in a V-shape.
Dovetail Mate (Cozio) 1100+
Pieces: Queen vs. King + 2 Pieces
🧠 Hook: "The Diagonal V."
Similar to the Swallow's Tail, but the Queen checks diagonally (contact check). The King's escape squares are blocked by his own pieces.
Damiano's Mate 1200+
Pieces: Queen + Pawn
🧠 Hook: "The Face Kiss."
A white pawn on g6 (or f7) supports the Queen. The Queen lands on h7 (or g7) right in the King's face. Often follows a Rook sacrifice on h8.
Lolli's Mate 1300+
Pieces: Queen + Pawn
🧠 Hook: "The Fianchetto Pry-Open."
A Pawn on f6 (wedge) creates a hook. The Queen invades to g7 or h6 to deliver mate. Similar to Damiano's but usually against a fianchetto structure.
Triangle Mate 1400+
Pieces: Queen + Rook
🧠 Hook: "The Geometry."
The Queen mates the King on the edge, supported by a Rook that is two squares away on the same file/rank. They form a triangle shape.
Max Lange's Mate 1500+
Pieces: Queen + Bishop
🧠 Hook: "The Support."

3. Bishop & Diagonal Patterns

Diagonal Corridor Mate 1000+
Pieces: Bishop + (Own Pieces)
🧠 Hook: "The Long Diagonal Trap."
A specialized mate where the enemy King is trapped on the long diagonal (e.g., King on h8 or King on a1). His escape is blocked by his own pieces or the board edge, creating a "corridor" for the Bishop to snipe from a distance.
Boden's Mate 1200+
Pieces: Two Bishops
🧠 Hook: "The X-Factor."
A beautiful cross-fire mate. One Bishop cuts off the escape squares (d7/e8), while the other Bishop delivers the checkmate from the opposite diagonal. Usually follows a Queen sacrifice.
Double Bishop Mate 1200+
Pieces: Two Bishops
🧠 Hook: "Parallel Lasers."
Distinct from Boden's mate. Here, two Bishops control parallel diagonals side-by-side to force the King into a corner or edge and deliver mate.
Damiano's Bishop Mate 1300+
Pieces: Queen + Bishop
🧠 Hook: "The Diver."
Different from the famous Damiano's mate (which uses a pawn). Here, the Queen and Bishop coordinate, with the Queen often diving into the position protected by the Bishop from afar.
Balestra Mate 1600+
Pieces: Queen + Bishop
🧠 Hook: "The Scissor."
The Bishop checks the King on the side of the board, while the Queen blocks the escape squares (diagonal and vertical) without giving check herself.

🧠 Hook: "The Sniper Team."
A Knight sits on g5 (blocking f7/h7), while two Bishops slice across the board to deliver mate.
Réti's Mate 1500+
Pieces: Bishop + Rook/Queen
🧠 Hook: "The Self-Block."
Famous from Réti vs Tartakower. The enemy King is trapped by 4 of his own pieces. A Bishop delivers the final blow from a distance.
Morphy's Mate 1300+
Pieces: Rook + Bishop
🧠 Hook: "The Corner Trap."
The King is trapped in the corner by his own Pawn and a Rook. The Bishop delivers the mate from a distance.
Pillsbury's Mate 1300+
Pieces: Rook + Bishop
🧠 Hook: "Morphy's Twin."
Almost identical to Morphy's mate, but the Rook delivers the check while the Bishop cuts off the flight squares.

4. Knight, Pawn & Special Mates

Pieces: Lone Knight
🧠 Hook: "Friendly Fire."
The King is completely surrounded ("smothered") by his own pieces. A lone Knight jumps in to deliver checkmate. Often follows the "Philidor Legacy" sacrifice.
Anastasia's Mate 1100+
Pieces: Rook + Knight
🧠 Hook: "Knight shuts door, Rook walks hall."
A Knight on e7 (or d7) blocks the King from moving sideways. The Rook delivers the final blow down the open file.

🧠 Hook: "The Bishop Glue."
The Bishop pins the King's flight squares from a distance, and the Knight delivers the mate.
Pieces: 2 Knights + Bishop
🧠 Hook: "The Sea Cadet Trap."
An opening trap where White sacrifices the Queen to mate the Black King in the center of the board using minor pieces.
Pieces: Pawn
🧠 Hook: "The Little Guy Wins."
A mate delivered by a Pawn, usually when the enemy King is surrounded by heavy pieces but cannot move.
Stamma's Mate 2000+
Pieces: Knight + King (vs Pawn)
🧠 Hook: "The Pawn Traitor."
A rare endgame mate where the opponent's own side-pawn blocks their King, allowing a Knight to deliver mate.
Greco's Mate 1200+
Pieces: Rook + Bishop
🧠 Hook: "The Corner Cut."
A Bishop cuts off the g8 escape square. The Rook delivers mate on the h-file. Often relies on the opponent's g-pawn blocking their own King.

5. Basic Checkmates (Endgame Fundamentals)

Queen Mate Basic
Pieces: King + Queen vs King
🧠 Hook: "The Box Closes."
The most common endgame mate. The Queen forces the enemy King to the edge of the board, then the friendly King moves in to support a "kiss of death" checkmate.
Rook Mate (Box Mate) Basic
Pieces: King + Rook vs King
🧠 Hook: "The Shrinking Box."
Using the Rook to cut off ranks or files, shrinking the "box" available to the enemy King until he is forced to the edge, where the friendly King helps deliver mate.
Bishop and Knight Mate Expert
Pieces: King + Bishop + Knight vs King
🧠 Hook: "The W Maneuver."
One of the hardest basic mates. You must force the enemy King into a corner of the same color as your Bishop to deliver mate.
