Chess Cards
by Edward Lovett
INTRODUCTION
I found the essence of this game in Sid Sackson's A GAMUT OF GAMES, Hutchinson & Co. (Publishers) Ltd., Second edition 1982. It is the first game discussed (entitled MATE), and played with a particular subset of 20 playing cards from a regular deck.
According to Sackson: 'In Hanover, Germany, in the year 1915, G. Capellen published a small booklet entitled "Zwei neue Kriegspiele!" (that is, "Two New Wargames!" ). Sackson infers that the timing was not right for the emergence of new war games "..while the reality of World War I occupied the center of the stage", as the booklet subsequently passed into obscurity. One of the games in the booklet was MATE, the heart of this article. 1
Note that this card game is not a game of chance; there is a unique playing mechanism to eliminate the 'luck of the draw' no matter how the cards are dealt.
In this game we have:
I have added the concept of using 'Chess Cards' in place of regular playing cards to give the game more of a chess 'flavour'. Further, the concept of 'foreplacing' a card (as specified in the original article) has been replaced by a more general concept of 'sacrificing' cards, and minor changes have been made to scoring, terminology and gameplay. I would refer the reader to the original article in Sid Sackson's book if a more definitive comparison is required.
Other than these 'cosmetics', it is G. Capellen who deserves
credit for the mechanics of this rather unique and interesting card game.
The Chess Cards for this game consist of a set of 20 cards comprising 5
piece types (Queen, Rook, Bishop, Knight and Pawn), each in 4 suits (Black,
Red, Yellow and White). The King is imaginary, but subject to 'threats'
by the Chess Cards in play.

1The other game was called Free Chess, and noted to
be a 'chess variant', although no rules were specified
in Sackson's book.
GENERAL PLAY
Lacking a card of the same suit, the opponent must then reply with a card of the same rank (that is, piece type), for example queen countering queen, bishop countering bishop etc. This card, the opponent's 'reply', is placed face up in front of him.
Failing to have a legal move in reply to a threat is deemed mate and the game credited to the player with the initiative.
The player who played the highest piece type (within a suit), or the highest suit (when piece type is played) has the initiative and leads for the next move.
Piece rankings are (from highest to lowest):
Queen > Rook > Bishop > Knight > Pawn
Suit rankings are (from highest to lowest):
black > red > yellow > white
For purposes of scoring a mate, each card is considered to have a value as follows (note that the particular suit is irrelevant for scoring purposes):
Queen=11 Rook=10 Bishop=4 Knight=3 Pawn=7
In case of a draw, neither player scores.
In its most elementary form (that is, no sacrifices have taken place), the
value of the mating-card is multiplied by the move number to obtain
the score:
Score = Mating Card Value x Move Number
For example, mating with a knight on the first move: Score = 3 x 1 = 3.
Mating with a Queen on the 10th move: Score = 11 x 10 = 110.
Note that, in advanced play (see below), additional parameters are used to
calculate the score.
At the conclusion of the first game, the players cards are exchanged, and another game is played with each player now playing with the other player's cards (note that this effectively eliminates the luck of the draw and makes the card game one of pure strategy).
The player who was the non-dealer of the first game opens the second game.
Playing two games as such constitutes a match. It is the player who has
accumulated the greater score at the end of the match that is deemed the
winner. The difference between
the two players scores at the end of the match may be used as
a relative measure of victory.
Note that games can be played quite quickly; a match typically lasts
< 30 minutes.
ADVANCED PLAY
As befitting her role as the most powerful piece in FIDE chess, the card-queen has a special privilege associated with her; on playing a queen, the player may announce 'Queen's Privilege' (an optional move) in which case the queen must be followed by another queen, if that player possesses one; if not, he follows with a card of the same suit. Note that this privilege can have a dramatic effect on the outcome of a game - please refer to the sample games section
To sacrifice a card, a player announces at the beginning of his turn that he wishes to sacrifice a card; he clearly shows it to his opponent and places it face down in front of him. The card does not enter into play. The player must then make a normal move.
The opponent at this or any subsequent time, also has the opportunity to sacrifice.
Sacrificing cards has strategic value and allows the greatest possible extraction of score from play. However, sacrificing too many cards inevitably leads to mate by your opponent!
Examples of play are examined in the
sample games section, but for the moment, let us consider some
calculations of score when sacrifice(s) have taken place
as we will need to understand this in relation to
the discussion of overmate which will be considered shortly.
The player who has sacrificed a card(s) and succeeds in giving mate has the
multiplying number of the move increased by one for each card
sacrificed.
(A common motif, when you know that you can force mate,
is to sacrifice a card just prior to delivering the mating card).
For example, a mate given in the seventh move by a bishop would
score as follows:
Score = 4 x (7 + 1) = 32 for one card sacrificed,
and
Score = 4 x (7 + 2) = 36 for two cards sacrificed.
Note that the 'multiplying number of the move' (the calculation
that occurs within the brackets) = move number + number of cards sacrificed.
Please note that these are but trivial examples of what may be achieved.
If players sacrifice different numbers of cards and the game proceeds to the point where the player who has sacrificed the greater number of cards has run out of 'cards in hand' to play, he must (and can only) use his last played card for all subsequent turns (depending on how many cards the opponent still holds) until the game is resolved.
I would refer the reader once more to the sample
games section for illustration.
The term overmate pertains to the situation where a player who has
sacrificed one or more cards succeeds, (by employing his 'last played card'
as mentioned above), in giving mate and the 'multiplying
number of the move' is then calculated to be greater than 10.
Remember that the 'multiplying number of the move' is incremented
by '1' for each card sacrificed, i.e.
'multiplying number of the move' = move number + number of sacrificed cards.
Thus, if a player has sacrificed, say, 2 cards and succeeds in
mating on the tenth move, his 'multiplying number of the move'
is going to be greater than 10 (10 plus '1' for each card sacrificed).
Anytime the 'multiplying number of the move' is calculated to be greater
than 10, this situation is known as overmate and
attracts further bonuses.
The overmate number
(see table below) is the number of units above 10; in the previous
example, the overmate number would be 2.
Overmate Number | Score is Multiplied by |
1 | 2 |
2 | 3 |
3 | 4 |
4 | 5 |
5 | 6 |
Since there is a maximum of 10 moves per game, and since each card
sacrificed must be followed by a 'normal move', then it follows that
a maximum of 5 cards could possibly be sacrificed by a player in a game.
Theoretically then, if move 5 by Player A was a Queen, and
mate was given on the tenth move by this player, he
having played his fifth card also as his sixth, seventh, eighth, ninth and
tenth cards, then his final score would be:
Score=mating card value x (move number + number of sacrificed cards)
x bonus
= 11 x (10 + 5) x 6 = 990 (theoretical maximum mate score), although it has
yet to be demonstrated that this can be achieved in actual play.
Please refer to the sample games section for an example of overmate.
All sample games have pictorial and text-notation representation.
PLAYING SUGGESTION
Initially, or whenever space allows, players may place their cards face-up in a row in front of them, ordered in suits and pieces if desired, so that all cards are in view during play.
