Eric\: Black is likely winning anyway, but i3 was an incorrect answer to the local tactics problem\:

Black's turn in area(j1,i2,i5,j5,k4,k1).

j9 would've given Black an escape for height-3 ladders.  This move k7 will leave Black with just an escape for height-2 ladders.]

C[Eric\: f8 is still a simple win, for the reason I showed 4 moves ago.

It appears Black eventually resigned without seeing that win, although other than that resignation, Black was still winning for the rest of the game.]
