Marguerites: a piece combining the powers of Grasshopper, Hamster, Sparrow, Eagle and Moose
Grasshopper (G): Hops on Q-lines over any one unit (the hurdle) to the next square beyond. Q-hopper would be a more sensible name.
Sparrow (SW): a grasshopper which pivots 135' (to either side) at the hurdle.
Eagle (EA): a grasshopper which pivots 90' (to either side) at the hurdle.
Hamster: moves like a Grasshopper but deflect 180o on passing over the hurdle.
Moose (M): a grasshopper which pivots 45' (to either side) at the hurdle.
Okapi: a piece combining the powers of Knight and Zebra
Zebra (Z): a (2,3/3,2) leaper, e.g. a1>d3 or a1>c4.
Neutral piece (n): A unit with this characteristic may be regarded as of either colour by the side whose turn it is to play. Neutral pawns promote to neutral pieces.
Koko Chess (Contact Chess):a move is legal only if the arrival square is adjacent to any piece, this applies also to the capture of king.
Maximummer: Black must play the geometrically longest move or may choose from among longest moves of equal length, distances being measured from the center of each square. Diagonal and oblique distances are measured from the orthogonal coordinates by using Pythagora’s theorem (take the square root of the sum of the squares of the orthogonal distances). All other orthodox chess rules apply.
