+
+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 as many moves
+  as the opponent just played plus one.
+
+p.
+  If a move gives check, then the sequence stops here, but the opponent can
+  still play as many moves as would be theoretically possible.
+  Also, if a checkmate or stalemate situation occurs before the maximal number
+  of moves are played, the game ends.
+  There are no en-passant captures.
