Ladder
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.
a | b | c | d | e | f | g | h | i | j | ![]() | |||||||||||||||
![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | |||||

![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() |
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.

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
