The Coup in International Draughts: Your First Combinations

A coup in draughts is a combination — a short, forced run of sacrifices and captures that ends with you clearly ahead or with a man crashing through to become a king. Coups are the most satisfying thing in International Draughts, and the good news is that the basic ones follow patterns you can learn. Once you know the shapes, you start seeing them on the board. Here is how coups work and the beginner patterns to start with.

How every coup works

A coup uses the maximum-capture rule as a remote control. You offer one or more pieces; the opponent is forced to take the biggest capture; and that forced capture marches their pieces off the squares you needed cleared — or lines them up for a sweep. Because they must play the maximum, they cannot wriggle out. The whole thing is calculated in advance, from the first sacrifice to the final count.

Two ingredients make a coup possible: a sacrifice you can afford, and a follow-up that is bigger than what you gave. If you give two and take three, or give one and promote a king, the coup is sound.

The breakthrough coup

The most useful beginner coup is the breakthrough: a sacrifice that forces enemy pieces out of the way so one of your men has a clear lane to the promotion row. You give a man — sometimes two — the forced captures pull the defenders aside, and your surviving man walks in to crown. A new king on the 10×10 board, sweeping whole diagonals while the enemy men still crawl forward one square, is often decisive on its own.

To spot one, look at the squares between your most advanced man and the far row. If a well-timed sacrifice would force the guarding pieces to capture away from that lane, you may have a breakthrough. Trace it: I give here, the maximum capture forces them there, and now nothing stops my man from promoting.

The lining-up coup

The second pattern uses the sacrifice to arrange the opponent’s pieces for a single big capture. You feed a man into a spot where the forced recapture places an enemy piece with an empty square behind it, right where your waiting man or king can start a chain. Now your capture sweeps through the row they just built. Give one, take three or four — that is a lining-up coup.

These appear most often when the opponent has crowded pieces together. A tight diagonal cluster is exactly the raw material a sweeping capture needs, so watch for the moment your opponent bunches up.

The two shapes often work together. A breakthrough that forces the defenders to capture can leave them lined up for a second sweep, and a lining-up sacrifice can clear the last guard off a promotion lane. Once you know both patterns, you start to see how one forced capture flows into the next, and short two-move coups grow into longer combinations that decide the game in a single turn.

Setting a coup up

You rarely get a coup for free; you steer toward one. Three habits make them appear:

• Develop toward the center so your pieces have the reach to deliver the final capture.
• Keep a spare man you can afford to give — a supported piece near the action that can be the sacrifice.
• Watch the opponent’s shape. Bunched pieces invite lining-up coups; a thin guard on the promotion row invites breakthroughs.

When you see the raw material, check each of your men to ask: if I sacrifice this, does the forced maximum capture help me more than it costs?

Avoiding the coup against you

Everything here works against you too, and losing to a coup you did not see is the most common way club games end. The defense:

• Treat any “free” piece with suspicion. A coup begins with a gift.
• Do not bunch your pieces into tight clusters where one capture chains through them.
• Guard your promotion row — do not let a single sacrifice clear a lane to your back rank.
• Before you make your forced capture, look one move further: what does taking the maximum let the opponent do next?

Practice the shapes

Coups reward pattern memory. The breakthrough and the lining-up shapes cover a huge share of what you will meet as a beginner, and once they are familiar you will spot them without calculating from scratch. Trace every capture on the board, yours and theirs, until seeing the whole forced chain is automatic.
