C[Eric's comments regarding E4\:

My immediate thought\:

This is way too slow.  (https\://senseis.xmp.net/?Slow)

Elaboration\:

White has put 3 net pieces in a 5-cell trapezoid.  It gives White the whole trapezoid, but still.  I guess https\://senseis.xmp.net/?Overconcentrated might be more accurate, but for some reason that was not my immediate reaction.

Consequence, which it took me a little longer to see\:

i4 now wins for Black, since F9 connects via E9 or E11.

Alternative\:

H3 connects to the A-edge, and looks much better to me.]
