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.

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
38 bishop or the queen.

41 Note: if you don't want to play a second part in a move, just click on any
42 empty square: this will replace the second part by an empty move.

55 pieces can exit the board by themselves, possibly dragging another piece

84 The game ends when a push or pull action threatens to send the king off the
85 board, and he has no way to escape it.

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