After Kd4, death, destruction, and loss of eyeballs. Look at how white's pawn
is completly frozen. Look at the thing that will be holding back black's pawn
is its own piece. Maybe it's less obvious than it appears to me. Perhaps a
chess expert like Miguel or Vincent or Djorde can say if it looks obvious to
them. For sure, I would resign this position immediately, unless I was playing
a numbskull.
