+p.boxed.
+ Moves are potentially played in two times: move a piece,
+ and / or push or pull something with that unit.
+
+p.
+ Pieces have the same movement as in orthodox chess, except that they cannot
+ take other pieces in the usual way. Instead of the normal captures, pieces
+ can pull or push other pieces, potentially off the board.
+ The goal is to send the enemy king off the board.
+
+p Each turn, a player has the following options:
+ul
+ li.
+ Move one of his pieces normally, then optionally pull something as an
+ effect of this move.
+ li.
+ Push any piece with one of his pieces, then optionally follow the pushed
+ piece.
+
+p
+ | It seems easier to understand with some examples. For a detailed
+ | introduction please visit

+
+p.
+ The e2 pawn can move to e3 and e4 as usual. It can also slide diagonally,
+ being pushed by the bishop or the queen (which may or may not move along
+ this line afterward). It can also go to c3, being pushed by the knight from
+ g1; then the knight can move to e2, or stay motionless.
+ Finally, the pawn can "take the king": this is a special move indicating that
+ you want it to exit the board. Indeed it could be pushed off the board by the
+ bishop or the queen.
+
+p.
+ Note: if you don't want to play a second part in a move, just click on any
+ empty square: this will replace the second part by an empty move.

+ It is forbidden to undo a "move + action". For example here, white could
+ push back the black bishop on g7 but not return to d4 then.

+ Check: the queen threatens to pull the king off the board along the a4-e8
+ diagonal.
+
+p.
+ Note: castling is possible as long as the king and rook have not moved and
+ haven't been pushed or pulled (this differs from the chessvariants
+ description).
+
+h3 End of the game
+
+p.
+ The game ends when a push or pull action threatens to send the king off the
+ board, and he has no way to escape it.

+
+p.
+ The king cannot "take" on g4: this would just push the queen one step to the
+ left, and she would then push the king beyond the 'h' file.
+ There are no en-passant captures.
