I believe this move is important for Black, since I don't see any other way for Black to make the ladder right from E9 work.]

Assuming Black can make the ladder right from E9 work - and I don't see any way for White to prevent that, against H5+J9 - this looks good for Black.]

This was my original idea with E7, but here it seems C10 will be a forcing move for White.]
