Pinched checkerboard

Andy_0306uk also built this pinched checkerboard. The explanation is the same here as the bulging checkerboard I posted a couple of days ago, but since the dots angle the other way it seems to pinch in rather than bulge out. I think the previously featured one works better because it has both black dots on the white squares and white dots on the black squares. Here the plain white squares seem to break the illusion somewhat.
