-	TODO: explain, every turn twice except if check on 1st turn, or
-	very first move in game.
-	En-passant: possible in any order if 2 ep squares,
-	otherwise has to be the first move.
-	OK even if opponent moved his pawn at subturn 1.
+	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

-	PGN game notation: since there are two moves at each turn except on move 1,
-	a double move in the game is indicated as two comma-separated (ordered) moves,
-	as in 3.Na5,Bd3 e6,f4 (the two first are white moves,
+	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).
-	Sometimes a move gives check, or stalemate occurs after subTurn 1 :: just one move

+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.
