A ladder is a situation in which both players move perpendicularly to an edge making a straight unbroken chain. The attacking player's chain is almost always further from the edge. Here is an example of the ladder starting from b4 and c3.
Red (vertical) to move. In this situation red has a sure win due to his ladder escape on j3. Of course he can start another ladder playing a4 but in that case, blue has a ladder escape on b2.
Pre-ladder formations
Ladder handling
There are three ways for the attacking player to "win" in a ladder situation:
- Making use of an existing ladder escape piece
- Creating a new ladder escape with a Ladder escape fork
- Cornering
