How many pieces do you typically need to play this game? The rules place no explicit limit in the size of the stack, although if a stack gets to be 8 pieces high, then it can't do anything other than leave the board, which puts an obvious theoretical maximum at no more than 64 pieces per side (4 checkers sets). I wouldn't be surprised if the actual theoretical maximum is lower than that.

I wonder if parametric definition (like a list comprehension) would be clearer... Interesting approach nevertheless.

  The 10x10 aspect of it appears to be because there's an invisible outer ring of "if your piece moves here, it is removed from the game" which wouldn't be possible with an 8x8 board that doesn't have an "outside". If you play the game, you'll see an 8x8 board.

  I wrote that .lud-file. There are 3 known issues with it: (1) The identity of a player's king is only updated after their own turn, not after each player's turn. (2) It is not always possible to suicide a stack that has the proper reach, because it might overshoot the mark (my code requires it to land exactly 1 step outside the board). (3) Suicided pieces are not removed if the resulting state has no uniquely talles stack of the current player's color. All of these issues are fixed in a new .lud-file written by someone else. (I usually write my own, but this is the second time the same guy has come to my rescue.)

I'd also love to know the upper bound on how long a game can be.
