BP20 Both dots touching same bulb vs. dots on opposite bulbs.
(edit; present; nest [left/right]; search; history)
COMMENTS

All examples in this Bongard Problem are outlines of smooth shapes with a pinch in the middle and with two tiny black circles attached to the outside of the shape (tangent).

A shape with either dot tangent to the the valley section would be ambiguous.
