e7 would have been an easy win for Black.  Black defends both bridges, uses D5 to get a switchback along the 1-edge, and climbs to G6 from a 2nd row ladder along the 11-edge.]

However, due to D5, it looks like this won't be enough for White.]

Since C7 can't be foiled, this looks extremely good for White.]
