Charles Gilman's solution is duals, and I think he would say compounds of duals are the better piece-types. Camel is Knight's dual and the compound Gnu, an old problemist piece, triangulates, like all duals. In fact, there are many Gnus in 'ECV'. Zebra's dual is Zemel(1,5 leaper) and the compound of the duals is called Zebu, another triangulator, good for planning moves, and you just start thinking of those squares together. However, these augmented piece-types are for boards 10x10 at a minimum and mainly 11x11, 10x12, 12x12. Since ''when gap widens'' weakens, they need to be compounds oblique -- in Chessboard math we exclude Bishop-diagonal being radial from ''oblique.'' http://www.chessvariants.org/index/displaycomment.php?commentid=2322 This started the original thread mid-2008: http://www.chessvariants.org/index/displaycomment.php?commentid=17586 Edit Form You may not post a new comment, because ItemID FatallyFlawedMM2 does not match any item.
