Today's puzzle is of the very-freshly pzprxs-implemented Sumiwake, a fun twist on Heyawake I think a lot of you will enjoy! Also, this is a genre with black and white circles for clues, which means I'm legally required to do an antisymmetric visual theme.

Rules: Shade some cells such that no two shaded cells are orthogonally adjacent and all unshaded cells form one orthogonally connected network. There must not exist a vertical or horizontal line of uninterrupted unshaded cells that crosses more than one region border. White circles indicate that the surrounding 2x2 has one shaded cell, while black circles indicate that the surrounding 2x2 has two shaded cells.

Not a GAPP 101, but a helpful solving tip to those who may find this genre more intractable than others (with varying levels of detail provided in separate spoiler tags): White circles orthogonally adjacent to black ones are restricted because of the black circles having shadeds in a checkerboard pattern around them, fulfilling the white circle on the side facing the black one.
