🎯 Forks, Pins & Skewers – Tactical Basics
These three tactical ideas — forks, pins, and skewers — appear in every level of chess. They are among the first patterns that beginners should learn to recognise and create. Mastering them will immediately improve your ability to spot threats, set traps, and defend effectively.
♞ Forks – The Double Attack
A fork happens when a single piece attacks two or more enemy pieces at the same time. Knights are particularly dangerous because they can jump to attack multiple squares at once, but queens, bishops, and pawns can also deliver powerful forks.
Forks often win material because your opponent can only defend one target. Common examples include a knight forking a king and rook, or a pawn advancing to attack two pieces simultaneously.
How to spot forks:
- Look for pieces on the same colour of square (e.g. both on dark squares) that could be attacked from a single point.
- Search for unprotected or overloaded pieces near each other.
- Keep your pieces coordinated so that they cannot be forked easily.
♗ Pins – Holding a Piece in Place
A pin occurs when a piece cannot move without exposing a more valuable piece behind it. Bishops, rooks, and queens commonly create pins along diagonals, files, and ranks.
For example, if a bishop attacks a knight that stands in front of its king, that knight cannot legally move — it is “pinned.” If the piece behind is not the king but still valuable (like the queen), the pin is called a relative pin.
How to use pins effectively:
- Pin an enemy knight or bishop to prevent it from moving or defending.
- Apply pressure with other pieces to increase the power of the pin.
- Be aware of breaking the pin — sometimes your opponent can push a pawn or block the line.
♕ Skewers – The Reverse Pin
A skewer attacks a valuable piece first, forcing it to move and revealing a less valuable piece behind it. Whereas pins paralyse, skewers chase — the target moves away, leaving something to be captured.
Skewers are most often seen along open files or long diagonals, using rooks and bishops. A typical example is a bishop checking a king, with a queen or rook exposed behind it.
Recognising skewer opportunities:
- Keep lines open — skewers rely on long diagonals or files.
- When you check or attack a major piece, look to see if something valuable lies behind it.
- Use forced moves (like checks) to align your opponent’s pieces into a skewer position.
🧩 How to Practise These Tactics
- Set up training positions featuring forks, pins, and skewers.
- Pause your games briefly and ask, “What is undefended?” — that question often reveals tactical shots.
- Study miniature games where one simple tactic decided the outcome.
- Try to combine these ideas: for instance, pinning a piece before delivering a fork elsewhere.
💡 Key Takeaways
- Forks, pins, and skewers are the foundation of chess tactics.
- They occur frequently — even grandmasters use them to win material.
- Improving tactical vision starts with spotting these basic patterns automatically.
✅ Summary
Whenever you make or face a move, scan for forks, pins, and skewers. They often decide games at the beginner level, and recognising them quickly is a major step towards tactical mastery.
