How to Play: 10×10 International Draughts (FMJD)
A bigger board, more pieces
International draughts, overseen by the world body known as the FMJD, is played on a larger 10×10 board, again on the dark squares only. Each side begins with twenty men arranged on the four rows closest to them. The bigger board and extra pieces make for longer, deeper games with more room to maneuver.
Men capture in every direction
An ordinary man still moves one square diagonally forward. But here is a key difference: when capturing, a man may jump an enemy piece either forward or backward. This backward capture for ordinary men means threats can come from any diagonal, and a piece that looks safe behind you may not be safe at all.
The maximum-capture rule
Capturing is mandatory, and this version goes further: you must make the capturing move that takes the greatest number of pieces. If one jump sequence wins three pieces and another wins two, you are required to play the one that wins three. You count the whole chain, not just the first leap, before deciding which capture is forced.
Flying kings and winning
When a man reaches the far back row it becomes a king, and here the king is a flying king. It glides any distance along a clear diagonal in one move, and when capturing it can jump an enemy piece from far away and land on any empty square beyond it. A single flying king can sweep across the whole board, which makes promotion enormously powerful. As always, you win by capturing every enemy piece or leaving your opponent with no legal move.
