ITALIAN PROGRESSIVE CHESS

This game is the most popular Chess Variant. A great number of tournaments of Italian Progressive Chess are organised:

RULES
    FIDE chess rules are in effect, with the exception of what follows
  1. The two players alternate series of moves of increasing length.
    White starts playing 1 move, black plays then a series of two moves, white plays then a series of three moves and so on.
  2. Series are a whole and no restriction is made on the kind of moves that can be made in a given series, with the only exception explained in the following point.
  3. A check can be administered only with the last move of a series.
    Similarly an opponent's check must be defended with the first move of the new series, In particular, if the only way of parrying a check has the effect of checking immediately the opponent's king, the game is lost (progressive checkmate).
  4. The en passant capture is allowed only when the three following conditions are satisfied:
    1. the to be captured pawn was pushed two steps ahead in the previous series and not moved further;
    2. the capture takes place as first move of the series.
    3. the square where the capturing pawn move is unoccupied.
  5. If a player has no legal moves available and it is not under check, even if this occurs in the middle of a series, the game is a draw (progressive stalemate).
  6. If no pawns are pushed or no captures take place for 10 series in a row, the game is a draw unless one color can prove a forced win.
Notation: it is customary to number the series consecutively, in relation with their lenght; so, for instance, 1. e2e4 2.e7e5 f7f6 3. Ng1h3 Bf1e2 Be2h5+ is preferable to 1.e2e4, e7e5 f7f6 2.Ng1h3 Bf1e2 Be2h5+, etc.. All players are strongly invited to adopt this convention. Games in article by Jens Baek Nielsen.
