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

-h3 Basics
-
-p.
- At the very first move of the game, white make only one move - as usual.
- However, after that and for all the game each side must play twice at
- every turn. There are two exceptions:
-
-ul
- li.
- If the first move gives check (maybe checkmate),
- then a second move isn't played.
- li.
- If no move is available after the first move, then it's stalemate
- and again, there is no second move.
-
-p.
- About the PGN game notation: when a side plays two moves in a row,
- they are separated (in order) by a comma in the PGN.
- Example: 3.Na5,Bd3 e6,f4 (the two first are white moves,
- the two others are black moves).

-h3 En-passant capture
-
-p.
- Capturing en-passant is allowed under certain conditions.
- If the opponent moved a pawn allowing such a capture (once or twice),
- then (to take it) you must capture en-passant at the first move of your turn.
- After that, if (and only if) there is another en-passant capture available
- you can play it on the second move.
-
-p.
- Note: if a pawn 2-squares jump was made and then a piece landed at the
- en-passant square at the second move, a pawn capture on this square
- takes only the piece.
- And, if a pawn advanced twice then en-passant capture
- on its first movement is impossible (the pawn is now "too far").
