| 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: |
| 12 | ul |
| 13 | li. |
| 14 | Move one of his pieces normally, then optionally pull something as an |
| 15 | effect of this move. |
| 16 | li. |
| 17 | Push any piece with one of his pieces, then optionally follow the pushed |
| 18 | piece. |

| 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. |

| 42 | a move, click on any empty square: this will send an empty move. |
