Jumping

In the following game, Red needs a ladder escape to the bottom ladder:

		a		b		c		d		e		f		g		h		i		j
1
2
3
4
5
6
7
8
9
10

Red can get this by going back — jumping — one row:

		a		b		c		d		e		f		g		h		i		j
1
2
3
4
5
6
7
8
9
10

Because now i8 is a working ladder escape fork:

		a		b		c		d		e		f		g		h		i		j
1
2
3
4
