15 | The only difference with orthodox chess is the double-move rule, |
16 | but this affects the game a lot. | |

21 | At the very first move of the game, white make only one move - as usual. |
22 | However, after that and for all the game each side must play twice at | |
23 | every turn. There are two exceptions: | |

27 | If the first move gives check (maybe checkmate), | |
28 | then a second move isn't played. | |
29 | li. | |
30 | If no move is available after the first move, then it's stalemate | |
31 | and again, there is no second move. | |

34 | About the PGN game notation: when a side plays two moves in a row, |
35 | they are separated (in order) by a comma in the PGN. | |
36 | Example: 3.Na5,Bd3 e6,f4 (the two first are white moves, | |
37 | the two others are black moves). | |

47 | Capturing en-passant is allowed under certain conditions. |
48 | If the opponent moved a pawn allowing such a capture (once or twice), | |
49 | then (to take it) you must capture en-passant at the first move of your turn. | |
50 | After that, if (and only if) there is another en-passant capture available | |
51 | you can play it on the second move. | |

54 | Note: if a pawn 2-squares jump was made and then a piece landed at the |
55 | en-passant square at the second move, a pawn capture on this square | |
56 | takes only the piece. | |
57 | And, if a pawn advanced twice then en-passant capture | |
58 | on its first movement is impossible (the pawn is now "too far"). | |
