+h3 Special moves
+
+p.
+ Castling is possible as in orthodox 8x8 game. The white king move to c1 or i1
+ (one square to the left of bottom-right corner) for large (resp. small) castle.
+ Same for black on the other side.
+
+p.
+ Promotion is mandatory for a pawn reaching the last rank. However, they can only
+ promote into a friendly piece captured (which is back on the board). If none is
+ available, the promotion on last rank is impossible and the pawn cannot move
+ (but still gives check).
+
+p.
+ Pawn promotion is possible (but not forced) on the two ranks before last,
+ only in an already captured (friendly) piece.
+
+h3 End of the game
+
+p As in the orthodox game, win by checkmating the king.
+
+p.
+ Note: I changed the author's starting position, to increase randomness
+ (and uniformize with other variants).
+ Thus the castling rule was introduced compared to the rules described
+ on chessvariants.com.
