Pawn peculiarities

Pawns capture differently from how they move (straight move, diagonal capture).
There is no initial double-push, and thus no en-passant capture.
Pawns promote to a piece chosen from the set of captured pieces, or to Soldier when they reach last rank. -The chosen piece is then removed from this set.

General rules

It is not allowed to expose your King to check.
The game is won by checkmating the opponent's King.
Stalemate (no legal moves, but not in check) is a draw.
If your opponent only has a King at the beginning of your turn, and your king is not yet bare, you win. -This means that after you capture the last piece, the opponent gets one equalizing turn to recapture yours, -in which case it would be a draw.

XBoard interface issues

-When a Pawn can be promoted, XBoard first advances it as a Pawn to the promotion square. -Then it waits for you to complete the move entry by clicking on the piece in the holdings beside the board that you want to promote to. -Initially there are a number of Soldiers available in the holdings, -for when you should promote before any of your pieces is captured. -

Differences with FIDE

-There are no sliders such as Rook, Bishop or Queen in this game: -their distant moves have all been replaced by a single two-square jumping move. -In addition it is more related to Capablanca Chess than to FIDE, -featuring compounds of Knight and the pieces substituting for Rook and Bishop, -and the wider board to accomodate them. -There is no double-push on the Pawns (and thus no e.p. capture), -and promotion only allows you to regain back a piece that you lost before, -or one of the stocked Soldier pieces that do not occur in the initial setup. -

Strategy issues

-Elephants are confined to squares of a single color. -Having Elephants on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value. -

-As the three strongest pieces (General, Minister and High Priestess) are nearly equal in value, under-promotion is very common. -
