+  | Nothing disappears in this game: captured pieces become part of the

+  | W >= 0, B >= 0 and W + B >= 1.

+h3 Captures
 
 p.
-  Simple moves are Ferz moves: one step diagonally.
   Captures work exactly as in Checkers: by jumping over a diagonally adjacent
   piece to land on a free square just behind.
-  However, the resulting situation is more complex. See below.
   If a capture is possible, then it must be played; in this case no piece can
   be introduced on the board.
+  If after a capture another is possible with the same piece, it must also be
+  played — except if that implies turning at 180 degrees.

-  Let us consider each unit as a compound entity containing W white pieces
-  and B black ones (initially W = 1 and B = 0 for white units,
-  and vice-versa for black).
-  Captures can then be described formally as follows.
-
-p.
-  As white:
-  If W1/B1 jumps over W2/B2 at square S2 to land on S1', then
-  W1/(B1+1) arrives on S1' and W2/(B2-1) remains on S2.

   If W2 = B2 - 1 = 0, nothing remains at the captured unit location.
-  As black: exchange W and B above.
+  As black: exchange W and B.
 
 p.
   In other words, each unit is a stack of friendly and enemy pieces, with
   friendly pieces on top. After each capture, the prisoners part of the
-  stack is incremented, while the "jailers" counterpart at the captured
+  stack is incremented, while the jailers quantity at the captured
   location decreases by one.
