ChessCarpenter: This mind numbing, brute force number crunching is the complete antithesis of why I play games. There's not an ounce of romanticism or sportsmanship to it. I suppose it has it's place in the realm of theory and understanding of games without chance in them. I'm glad to hear the numbers are so large as to make it more or less impossible to know every single outcome possible. There's other ways to do it besides knowing every move possible. A set of rules for each group of remaining pieces might use less memory, but I have the feeling that's not the case in this instance. Have you tried this approach? And then there's SMIRF Engine's point about just what good will such tables be if the game is already decided when it gets to that point? It's amazing that just having the extra 16 squares and the addition of four pieces on the board makes the numbers get so much larger. Regular Chess itself has very big numbers when one wants to count all the moves possible. What about the 10 × 10 board for Grand Chess? It uses the same pieces as Embassy Chess. Will the number be slightly more, or lots more? I'm thinking lots more. Though the restricted Pawn promotion might keep it down more than the unrestricted Pawn promotion of Embassy Chess.

What's a Chancellor and Archbishop? There's no game on this site with those pieces. Do you mean the Marshall and Cardinal or Janus? They are not new pieces. They're more than 100 years old.
