Mate was originally published in the pamphlet "Zwei neue Kriegspiele!" (that is, "Two New Wargames!") by the German chess player G. Capellen in 1915 as Matt.
Mate is a game of perfect information played with a 20 card deck. It is played in matches of two rounds and rounds of two games. Players exchange hands between the two games of each round, which eliminates luck of the draw. A winning move or "mate" consists of playing a card that the other player cannot follow either in suit or rank. A point score for the game is calculated from the rank of the mate card and the total number of moves in the game (the more the better). The player with the most points wins the match.
Rules for Mate in Adobe Acrobat, formatted to fold into a 2.5" x 3.5" size that fits in a tuckbox with cards. I've distilled different sets of rules into the set I personally prefer. For more, see: http://forums.superdupergames.org/viewtopic.php?p=7411
This file contains a poker-sized card set (with back graphic, rules, and blanks) for Edward Lovett's slightly reworked rules of "Mate," called "Chess Cards" (http://www.chessvariants.org/cards.dir/chesscards/index.html). These are full-quality jpgs. Source files are available if you really want them.
Suit priority (in colour) goes from darkest to lightest and (by shape) from most edges to fewest. Feedback warmly welcomed. (Version 1.0)
