[lxcgpaqx] Crazyhouse small endgames

Consider positions in crazyhouse or shogi in which the total number of pieces on the board and in the hands of both players, is very small, similar to chess endgames.  Such positions can never occur in a actual crazyhouse or shogi game because the total number of pieces remains constant from the beginning of the game.

With a small number of pieces, ground truth can be calculated with a tablebase.  Are there any interesting endgames?

This is different from tsume shogi, which assumes all the remaining pieces are in the hand of your opponent.
