Chess Tactics for Beginners: Forks, Pins, and Skewers Explained

A fork is when a single piece attacks two (or more) of your opponent's pieces at the same time. Since they can only move one piece per turn, they'll almost always lose one of them.

Forks can be executed by any piece — but the Knight fork is the most dangerous because Knights move in an L-shape that's uniquely hard to visualize. The Queen and pawn are also excellent forking pieces.

Example: The Knight Fork

White plays Nd5, simultaneously attacking the Black King on c7 and the Black Rook on f6. Black must respond to the check — and loses the Rook.

White plays: Nd5+
  → Attacks King on c7 AND Rook on f6
  → Black must move the King
  → White captures the Rook next move

Knight on d5 forks Black King (c7) and Black Rook (f6)

Why Knights are the best forking pieces:

• Knights jump over pieces — they can reach squares that no other piece can reach in a cluttered position
• Their L-shaped movement is the hardest to visualize, so opponents often miss the threat entirely
• A Knight on a central square (d5, e5, c5, f5) attacks up to 8 squares simultaneously
• Knights threaten two types of targets at once: distant squares that seem unrelated

Pawn forks are also powerful:

Example: White pawn on d5, Black Knight on c6 and Black Bishop on e6
White plays: d5-d6? No — try this setup:
White pawn on e5 moves to e5×f6 or d6 to attack both pieces

Pawn forks work because pawns are cheap — trading a pawn to win a piece is almost always worth it. Watch for positions where a pawn advance would attack two undefended pieces at once.

💡 Practice spotting Knight forks by working through the tactics modules in the course. Once your brain has seen the pattern a hundred times, you'll start noticing fork setups three or four moves before they arrive. See Module 4 (Tactics & Pattern Recognition) for structured practice.

A pin is when a piece can't move because doing so would expose a more valuable piece behind it to attack. Pins are uniquely powerful because they restrict your opponent's choices — sometimes for many moves in a row.

There are two types of pin: an absolute pin (the piece behind is the King — moving is actually illegal) and a relative pin (the piece behind is valuable but not the King — moving is legal but costly).

Example: The Absolute Pin

White's Bishop on g5 pins the Black Knight on f6 to the Black King on e7. The Knight cannot legally move — any move puts the King in check, which is not allowed.

White plays: Bg5
  → Bishop on g5 attacks Knight on f6
  → Knight is pinned — moving it would expose King on e7 to Bishop
  → Moving is illegal (absolute pin to the King)
  → White can now attack the pinned Knight with Nd5 or h4-h5

White Bishop (g5) pins Black Knight (f6) to Black King (e7)

How to exploit a pin:

• Pile onto the pinned piece. Attack it with another pawn or piece. The opponent can't simply move it to safety.
• Advance a pawn to attack the pinner. Your opponent might try to break the pin with a pawn (like h6 in the example above to chase the Bishop). Plan for this.
• Use the pin as a distraction. While the opponent is focused on the pin, build threats elsewhere on the board.

Example: The Relative Pin

White Rook on e1, Black Queen on e5, Black King on e8
White plays: Re1 (or Rook was already on e1)
  → Black Queen on e5 is pinned to Black King on e8
  → Moving the Queen loses the King to check — very bad
  → But unlike an absolute pin, Black CAN move it — at huge material cost

Relative pins are sneaky because your opponent can break them — but it usually costs them a piece or creates another problem. Always ask: "if they move the pinned piece, what do I win?"

💡 Pins are at the core of many opening systems. The Italian Game and London System both create pin pressure early. See Module 5 (Strategic Thinking) to understand how opening piece placement sets up tactical opportunities like pins.

A skewer is the pin in reverse. Instead of attacking a less valuable piece that shields something more valuable, you attack the more valuable piece first. It moves out of danger — and you capture the less valuable piece that was hiding behind it.

Think of it like a kebab: you stab through the big piece to get the smaller piece behind it. The big piece has to move (or it gets captured), and whatever was behind it gets taken.

Example: The Rook Skewer

White plays Re8+, giving check to the Black King on e8. The King must move — and White then captures the Black Rook on e5 for free.

Position: White Rook on e1, Black King on e8, Black Rook on e5
White plays: Re1-e8+  (check!)
  → Black King must move (say to d7 or f7)
  → White plays: Re8×e5  (captures the Rook left behind)
  → Result: White wins a Rook for nothing

White Rook (e1) skewers Black King (e8) — after King moves, White takes Black Rook (e5)

What makes skewers so effective:

• The opponent is usually forced to comply — if the attacked piece is the King, they must move it (it's check)
• Even with a relative skewer (Queen or Rook attacked, not King), the piece is often too valuable to sacrifice
• Skewers work along files, ranks, and diagonals — Rooks, Bishops, and Queens are all skewer weapons
• In endgames, King + Rook skewers are extremely common winning techniques

Bishop Skewer Example:

White Bishop on b2, Black Queen on f6, Black Rook on h8
White plays: Bb2-a1? No, consider:
White Bishop on a3, Black King on f8, Black Rook on h8... wait.

Simpler:
White Bishop on b2 attacks along the diagonal g7→f6→e5→d4→c3→b2
If Black Queen is on g7 and Black Rook is on d4:
White plays: Bb2-g7+ or adjusts position to skewer along diagonal

The diagonal skewer is trickier to spot because diagonals are less intuitive than ranks and files. But once you see how Bishops and Queens can "shoot through" pieces along diagonals, you'll start spotting them everywhere.

💡 Skewers are especially common in Rook endgames, which is why understanding piece coordination in the endgame matters. Module 6 (Advanced Tactics) walks through skewer patterns across multiple piece types with hands-on exercises.
