I've edited my previous post a bit to try to clarify some omissions to the rules of my Bloodline variant idea. [edit: I did a few minor edits to this end a bit later, too. P.S.: I now think 'Royal Succession' is a better name for this variant idea.]
Here's a diagram of a Black lone royal queen being final checkmated by White's K and 2 (clearly non-royal) queens, winning the game (don't know if this material balance is a forcible 'basic final checkmate', but I suspect so):
[edit: Note to self: it looks like it might often be too hard to end up with sufficient final checkmating material in a well-played game. Maybe I can salvage this variant idea if I ditch the royal succession rules and consider just mating a K as usual to be the game's objective (then rename, e.g. call it 'Squash Chess'; below is a 2nd setup I might use for it that uses only moderately stronger armies, perhaps, than in {6x6} Los Alamos Chess). A possible problem is that archbishops might often be traded fairly soon in a game:]
[edit: Here's a 3rd possible setup for Squash Chess that uses armies IMO about the same in value as the Los Alamos Chess ones, on 6x6 (I'd rate the colour-bound BD piece {i.e. moves as B or leaps two squares orthogonally} as worth approx. 5.47, or very close to a R in value, on this board, making for more interesting trades during games). A possible problem is that at times BD pieces might be traded quickly if they take an initial leap forward (if waffles were used instead, there could be a similar possible problem):]
