In equilateral triangular boards, Queen is broken down into Rook and Bishop, and there are the expected more than one Bishop binding(details under review). Rook always starts a move across a side, and Bishop the cell just beyond the accepted Rook side, she between his pathways so to speak. Rook and Bishop move parallel in the same direction. Eventually Rook could get to that Bishop's path-spaces one and all along the ways, but that Bishop never could get to that adjacent Rook's cells. Two opposite Bishops pairwise never will cohabit. For example, number 5^3 as 1;234;56789;10,11,12,13,14,15,16. Then Rook at 17 moves along 18,10,6 to 3 if four-stepping. Bishop from 17 would go -10,5,2,1. All four longstanding fundamentals are there, but Falcon more than the others needs practically at least 6^3. As well, more effective for 7^3 and up would be long-range leapers (4,0), (4,1), (4,2), (5,0) etc. as the boards enlarge. Of course all those have arrival cells beyond Knight and Falcon and between Rook and Bishop. There is not the dual subdivision per quadrant between Rook and Bishop of straightforward smoothed-out squares and rectangles. Instead, all the ''oblique'' ones have the full set of spaces between Rook/Bishop and Rook/Bishop, 120-degree separated, to themselves in any given notional move from a same hypothetical starting triangle. It is better to study the concepts on at least 8^3. In off-Chess science, as noted before, whether squares or triangles, ''oblique'' just means directions not Bishop-like and not Rook-like. So for instance in squares, along the Bishop diagonal is not oblique, as supposed to be in math. Edit Form You may not post a new comment, because ItemID ChessboardMath11 does not match any item.
