C[Black has an escape fork at j2, but no obvious way to use it. 

Black's a3 does not serve as an escape for 4th row ladders. 

The a3 escape trick only works for 3rd row ladders.

Also, a3 is not sufficient for a foldback underneath.

Manbe jumping at d4 would work.]

C[Jumping to d4 may have worked at this point. See next variation to see how it might have played out against Mohex.]
