No.989, 990 by Václav Kotěšovec – Two long serial miniatures. (JV)

Definitions:

Grasshopper (G): Moves along Q-lines over another unit of either color to the square immediately beyond that unit. A capture may be made on arrival, but the hurdle is not affected.

PWC: When a capture is made, the captured unit (except a King) is replaced on the square the capturing unit just leaves. A Pawn is immovable on its 1st rank.

Kangaroo (KA): Moves along Queen-lines like a Grasshopper, but over 2 hurdles (which may or may not stand on adjacent squares) to the square immediately beyond the second hurdle. A capture may be made on arrival, but the hurdles are not affected.

KoeKo: A move is possible only if the piece moved arrives on a square next to another unit.
