Note that 0.00 is an equal-material draw score or a draw by repetition.
-0.01 is a drawn tablebase game with white being down in material. IE a
drawn KR vs KRP ending.
+0.01 is a drawn tablebase game with white being up in material, as in a
drawn KRP vs KR ending.
Took a bit of time to see draw and a good bit of time to get off Ke8 which
appears to lose.
