Progressive Chess is perhaps the most widely played of all variants. It is unique in that each player makes one more move-per-turn than his opponent has made: White makes 1 move, black makes 2 moves, white makes 3 moves, and so on. The game quickly reaches a 'critical mass' as each player's move rate continues to grow. Games are intense, and few last for more than seven successive turns.
Boards and pieces
Although the Progressive Chess concept can be applied to almost any variant, the game is typically played as a variant of
board and pieces.
There are three main variants of Progressive Chess:
Players alternately make a
of moves of increasing number: White makes 1 move, black makes 2 moves, white makes 3 moves, and so on.
When a player gives check prior to the end of a sequence, he forfeits any remaining moves. His opponent's subsequent turn is not truncated, so the number of moves allowed for any given turn, is only dependent on the turn number.
Pieces move in democratic
Each mobile piece must move once before it can move twice, and each mobile piece must move twice before it can move thrice, and so on.** (If a blocked piece becomes mobile in a later cycle, it may not make 'catch-up' moves.) A just-promoted piece is considered having moved. Castling counts as having moved both King and Rook.
A player may not expose his King to check during a sequence of moves, even if the check is only temporary.
A check must be nullified on the first move of a turn. Failure to do so is checkmate.
When a player gives check at the end of a
he forfeits any remaining moves in that sequence. However, this forfeiture does not effect subsequent sequences: He and his opponent will have the same number of moves in subsequent sequences that they would have had, had he not forfeited previous moves.
It is customary to number the sequences consecutively, according to their length:
is preferable to...
1. e2, e4
1. e2 e4, e7e5 f7f6
2. e7e5, f7f6
2. Ng1h3 Bf1e2 Be2h5+,
3. Ng1h3 Bf, 1e2 Be2h5+
I strongly urge players to adopt this notational system.
Italian Progressive Chess
There are a great number of Italian Progressive Chess tournaments:
Alessandro Castelli: Scacchi progressivi. Finali di partita (Progressive Chess. Endgames), Macerata-Italy 1997.
English Progressive Chess
This game is played regularly in Italy, USA and Ukraine.
Tony Gardner (USA) and Alessandro Castelli (Italy) co-champion - 1st International Championship.

Scottish Chess is the oldest of all progressive chess variants, probably originating in Great Britain (or possibly Scotland) just before World War II. The game is also known as Scotch Chess, Blitz Chess, Lightning Chess, Speed Chess, Avalanche Chess (which is also used for another chess variant), Scottish Progressive Chess, or just Progressive Chess.
The variant is very popular. Two email tournaments were held, one in 1992/1993, and one in 1996.
