'DEF,LargeCV': A novel circular chess, Flipworld may not have erased all ambiguity about transit through its six Nexus cells(triangles), but there will not be the ridiculous bottleneck of Conveyor Chess or In the Bin. RNBKQP get two additions, weak Tocop and strong Starman, which could be explained better. The inner circuits will have most of the action. Really the Nexus, or tunnel, or lift, is not common to both Topside and Flipside, because player specifies which it is on if a piece stops there. Tesselations mixed square- and triangle-boards, like Round Table Chess, stretched topologically to over-all roundness, can play better than hexagonal ones once rules clarify. Games would be brief here for reason of traps, trades, errors.
