Z-Chess is a cross between the game of GLE'X and conventional chess. Two GLE'X boards put together - overlapping in the middle - make up the playing field. Conventional chess pieces - with the addition of a second Queen - are used to play the game. The goal, just like in the ancient game, is to capture the opponent's King. The strategy is similar as well, however, the nature of the Z-Chess board requires the pieces to move differently. The Rooks are more powerful than the Queens, resulting from the way they move. A single Rook attacks all 77 'squares' when other pieces are removed from the board. The 'squares' actually are circles at the intersections, same way as on the GLE'X board.As of March, 2002, over a thousand of Z-Chess games have been played by conventional chess Master Jamie Crosby, FIDE-Master Laszlo Bekefi and Expert Zoltan Bartok in Salt Lake City, Utah. The conclusion of the masters: Z-Chess is a breath of fresh air for the many tournament chess players tired of over-analyzed openings. - BoardGameGeek
