No.881, 882 by Erich Bartel – Interesting promotions in a play controlled by Madrasi RI & Alphabetic Chess. (JV)


Definitions:

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.

Alphabetic Chess: The squares are considered in the order a1, a2…a8, b1…b8, c1 and so on to h8. At each turn, only the unit standing on the square which comes earliest in this order may move. However check and mate are normal.

Madrasi: Units, other than Kings, are paralysed when they attack each other. Paralysed units cannot move, capture or give check, their only power being that of causing paralysis. Madrasi RI (rex inclusive): the rule applies to Kings as well, so the two Kings may stand next to each other.

Nightrider(N): Operates along straight lines with squares lying a Knight’s move away from each other.

Gnu(GN): Knight+Camel. Can move like a (1,2) Leaper and like (1,3) Leaper.

Lion(LI): Moves along Queen lines over another unit of either color to any square beyond that unit. A capture may be made on arrival, but the hurdle is not affected.

Antelope(AN): (3,4) Leaper.

Root-50-leaper(RF): (1,7 or 5,5) Leaper – moves by the diagonal of a rectangle whose length is equal to the square root of 50.
