A skewer in chess is a tactic where you attack a valuable piece, forcing it to move, and capture the less valuable piece that was hiding behind it. It’s the pin in reverse: in a pin the valuable piece is in back, but in a skewer the valuable piece is in front, gets attacked, runs away, and exposes whatever was behind. That’s why it’s nicknamed the pin’s “evil twin.” Like pins, only bishops, rooks, and queens can do it.
Let’s unpack how skewers work, how they differ from pins, and how to keep your own pieces off the kebab.
The 10-second version
- A skewer attacks a valuable piece in front, forcing it to move and exposing a piece behind it.
- It’s a pin flipped around — valuable piece in front, not in back.
- The strongest skewers attack the king (it must move), winning the piece behind.
- Only bishops, rooks, and queens can skewer — the line pieces.
How does a skewer work?
Like a pin, a skewer needs three pieces on one straight line: your attacking piece, the enemy’s valuable piece, and a lesser piece right behind it. You attack the valuable one — often with check — and since it’s too important to lose, it moves out of the way. The instant it does, the piece behind is left out in the cold, and you grab it.
Here’s the cleanest example, a bishop skewer with check:
White plays Be5+. The bishop checks the king on g7 along the long diagonal, and the rook on h8 sits right behind. A check is non-negotiable — the king has to move. The moment it steps off the diagonal, Bxh8 captures the rook. The king’s high value is exactly what dooms the rook: it can’t just stand there and shield its friend.
How is a skewer different from a pin?
This trips up a lot of players, so here’s the clean version. Both line up three pieces; the difference is which piece is in front:
| Pin | Skewer | |
|---|---|---|
| Valuable piece is… | Behind (shielded) | In front (attacked) |
| What happens | Front piece is frozen | Front piece is forced to move |
| You win | The pinned piece (after piling on) | The piece behind (immediately) |
| Mental image | Treasure hiding behind a guard | Treasure shoved aside, loot grabbed |
The neat way to remember it: in a pin, the front piece is stuck (it daren’t move because it’s protecting the treasure behind). In a skewer, the front piece is spooked (it’s the treasure, so it flees — and abandons whatever was behind it). Pin = protect; skewer = flee. If pins still feel fuzzy, our full pin guide lays out the mirror image in detail.
Can rooks and queens skewer too?
Yes — any line piece can skewer. The bishop does it on diagonals; the rook and queen do it on ranks and files (and the queen on diagonals too).
White plays Rh1+ along the h-file. The king on h4 is in check, and the queen sits behind it on h8. Notice the lovely detail: the king is blocking its own queen from capturing the rook, so the queen can’t bail it out. The king has to step off the file, and then Rxh8 wins the queen — a whole queen for nothing. Rook and queen skewers like this are especially common in the endgame, when the board’s wide open and kings and queens get caught on the same line with nowhere to hide.
How do you set up and spot a skewer?
The skewer’s favorite hunting ground is wide-open lines. Here’s how to find them:
- Look for enemy pieces on the same rank, file, or diagonal — especially a more valuable one in front of a lesser one.
- The king-in-front skewer is gold. If you can check the king and there’s a piece behind it on that line, the king must move and the piece is yours.
- Use checks to force the issue. A skewer with check is unstoppable, because the front piece (the king) has no choice.
- Watch the endgame. Fewer pieces, open lines, exposed kings — skewers blossom when the board clears out. (Strategy and tactics work together here: trading down often creates the skewer.)
How do you avoid getting skewered?
Defense is mostly about not lining your own pieces up like sitting ducks:
- Don’t put your king and queen (or king and rook) on the same open line. That’s a skewer waiting to happen.
- Keep valuable pieces off long open diagonals and files where an enemy bishop, rook, or queen can take aim.
- Block with a pawn or minor piece if a skewer is threatened — interpose something between the attacker and your king.
- Defend the back piece. If the piece behind is protected, the skewer might just trade evenly instead of winning material.
- See it coming. Same as always — run the CCT scan (Checks, Captures, Threats) and notice when your pieces are dangerously aligned.
A fun bit of skewer history
The name says it all: a skewer is the kitchen tool you stab through a kebab, hitting everything in a line. The chess skewer does exactly that — your bishop or rook “spears” two enemy pieces along one line, the front one and the one cowering behind it. In some countries it’s even called a “thrust” or “X-ray attack,” because your piece’s power passes through the front target to threaten the one behind once the front piece scrams. Whatever you call it, the picture’s the same: two pieces on one stick, and you’re about to eat well.
Common skewer mistakes to dodge
- Confusing it with a pin. Remember: pin = valuable piece behind (frozen); skewer = valuable piece in front (forced to flee). Front-to-back is the whole difference.
- Lining up your king and queen. The most common way to get skewered. Keep royalty off shared open lines.
- Skewering toward a defended piece. If the back piece is guarded, you win nothing — check that the loot is actually loose.
- Missing endgame skewers. When the board empties out, kings and queens roam open lines. That’s prime skewer territory — stay alert.
Key takeaways
- A skewer in chess attacks a valuable piece in front, forcing it to move and exposing the lesser piece behind it.
- It’s the pin reversed: valuable piece in front (skewer) vs. behind (pin).
- The strongest skewers hit the king — it must move, so the piece behind is lost.
- Only bishops, rooks, and queens can skewer; they thrive on open lines and in the endgame.
- Avoid getting skewered by keeping your king and valuable pieces off the same open rank, file, or diagonal.
