2 Moves are potentially played in two times: move a piece,
3 and / or push or pull something with that unit.
6 Pieces have the same movement as in orthodox chess, but they cannot
7 take other pieces in the usual way. Instead of the normal captures, pieces
8 can pull or push other pieces, potentially off the board.
9 The goal is to send the enemy king off the board.
11 p Each turn, a player has the following options:
14 Move one of his pieces normally, then optionally pull something as an

32 The e2 pawn can move to e3 and e4 as usual. It can also slide diagonally,
33 being pushed by the bishop or the queen (which may or may not move along
34 this line afterward). It can also go to c3, being pushed by the knight from
35 g1; then the knight can move to e2, or stay motionless.
36 Finally, the pawn can "take the king": this is a special move indicating that
37 you want it to exit the board. Indeed it could be pushed off the board by the
